Reliable connections.

You can rely on WISKA not only for the exciting exchange of ideas at the stand and at the stand party on Wednesday, 2 September 2026, from 5 pm. For years, the VARITAIN® reefer container sockets have been the market-leading solution for a reliable power supply on the high seas and in port facilities. The range of lighting and CCTV cameras enhances visibility on board and contributes to safe passage across the world’s oceans. Inspired by the first WISKA product – a cast brass cable junction box – the extensive range of cable entries and junction boxes is also consistently designed for use in harsh maritime environments.

Clear perspectives.

The range of WISKA cable glands in accordance with the VG standard is being expanded. New additions to the range include cable glands compliant with VG 88846-4 in Type B with VG earthing inserts, as well as in Type C without earthing inserts. Available in nominal sizes from M12 to M80 with type A strain relief. In the German Armed Forces’ equipment and information technology sectors, there is a demand for products that comply with this standard.

In the area of technical outdoor lighting, WISKA offers an impressive range of LED lighting that is particularly well-suited to refit projects. The LED floodlights include the LED Floodlight 5010 and the LED Floodlight 5000. The LED Floodlight 5010 offers a high luminous flux, is available in 1 x 220 W or 2 x 220 W versions and features a separate ballast. The LED Floodlight 5000 is available in four variants ranging from 1 to 4 x 40 W and is ideal as a replacement for traditional halogen floodlights. The range is complemented by the LED luminaire 4010, which enables the replacement of luminaires with fluorescent tubes and comparable MPL systems in engine rooms, corridors and technical areas. The LED searchlight rounds off the range. With a light output of 2 x 18,000 lm, IP66/68 protection ratings and features such as endless rotation, stepless speed control and Morse code operation, it offers maximum versatility and is conveniently operated via a remote control unit.

The highlight of the WISKA CCTV portfolio is the CS-S camera series, featuring a 360° pan-tilt unit, 512x zoom, 4-megapixel resolution and an operating temperature range of -30 °C to +55 °C. As part of its ongoing product optimisation and in light of global requirements, WISKA focuses on CE compliance, secure updates, vulnerability management and robust evidence for networked CCTV systems in the maritime environment.

All products are developed in-house by WISKA; the entire value chain is managed by WISKA. At SMM, WISKA will be exhibiting in Hall B6, Stand 212.

The achievement marks a major milestone for the company, which has progressed from its first EcoVadis assessment to Gold level in just three years. This rating places WISKA among the top 5% of companies assessed by EcoVadis worldwide at the time of rating.

EcoVadis evaluates organisations across four key areas: environment, ethics, labour & human rights, and sustainable procurement, providing an independent benchmark of environmental and social impact across operations and supply chains.

For WISKA, sustainability is embedded within the company’s culture and long-term strategy. The organisation continues to focus on balancing economic performance, environmental responsibility and social impact, supported by strong environmental management practices and continuous improvement across the business.

Tanja Hoppmann, General Manager and Head of Sustainability at WISKA Hoppmann GmbH, said:

“We are incredibly proud that our efforts to make WISKA more sustainable have been recognised with the EcoVadis Gold medal. This achievement means a great deal to us because it reflects the dedication and commitment of colleagues across the entire WISKA team around the world. Sustainability is something we work on every day, and we strongly believe that innovation plays a key role in creating better, more responsible solutions for our industry. This recognition motivates us to keep pushing forward, continuing to innovate and improving the way we operate.”

The EcoVadis Gold rating reinforces WISKA’s commitment to continuous improvement and responsible business practices.

Moments that connect.
Experience many exciting stations at the WISKA exhibition stand that will leave a lasting impression. Interact with the new products from the junction box and cable entry ranges – both classic and innovative! Be inspired and impressed by our clever solutions. There will also be celebrations. On 9 March, WISKA invites you to a stand party where you can relax and celebrate together after an intensive day at the trade fair.

Another highlight at the trade fair is part of WISKA's sponsorship programme: the hot air balloon of the Schleswig-Holstein Association of Electrical and Information Technology Guilds is located at the exhibition grounds (Agora) and takes visitors up and down. With this sponsorship, WISKA is sending a clear signal about its own origins and its commitment to the skilled workers of tomorrow.

Connections that are made to last.
This is ensured by the new COMBI^® 310 and COMBI^® 2516 junction boxes. With the new variants, WISKA's COMBI® series now comprises a total of 11 sizes, making the series even more versatile. The COMBI^® 310 junction box, a masterpiece, is compact and spacious with dimensions of 117 x 85 x 51 mm and features the typical COMBI^® design with a domed cover, which provides 10% more installation space. This box has 10 x M20 combined threaded and membrane entries as well as 4 rear entries. The new COMBI^® 2516 is now the largest version in the COMBI^® series. Measuring 260 x 200 x 125 mm, it offers significantly more space with a large clamping range of up to 25 mm².

The new 788 ESKV 32 cable connector offers perfect installation options in the smallest of spaces and enables two cables to be connected with ease. The 788 ESKV 32 is the updated version of the original PG version and is available with a 5-pole, 6 mm² screw terminal or with 5 WAGO 221-2411 terminals.

The COMBI^® 304 system is being expanded
There are now four products that enhance your installation in a wide range of areas. The COMBI^® 304 system from WISKA now consists of a rotary switch, a junction box, an LED light and a new socket! The closed type F socket, with IP54 protection, 4 x M20 combined threaded and membrane entries and dimensions of ø 82 x 76 mm, is the perfect addition to the system for providing a power connection in outdoor areas, e.g. for a robotic lawn mower.

We say goodbye to a beloved mother and grandmother who was not only the heart of the family, but also a formative part of the family business. As a longtime managing director and shareholder of WISKA, she helped shape the company over many years with her values and commitment. She lives on in our memories and stories – as a role model and inspiration.

“For us, sustainability is not an add-on, but an integral part of our corporate strategy,” explains Tanja Hoppmann, Managing Director of WISKA Hoppmann GmbH. “With this report, we want to show how we balance ecological, economic, and social responsibility.” 

WISKAs strategy is based on three key areas of action: 

Responsibility for the environment: Measures to reduce energy consumption and greenhouse gas emissions and to strengthen the circular economy. Responsibility for employees: Promotion of attractive working conditions, health, safety, and further training. Corporate responsibility: Transparent corporate governance and responsible action along the supply chain. 

The company is publishing a sustainability report for the first time in accordance with the Voluntary Sustainability Reporting Standard for SMEs (VSME). Participation is voluntary – but for WISKA, it is a clear commitment to responsible action and transparency. 

In the reporting year, WISKA implemented numerous initiatives, including:

• Bicycle leasing for employees to promote sustainable mobility.
• The development of a guideline for sustainable procurement and other internal guidelines.
• Introduction of bioplastics: The KA-BIO product range consists of renewable raw materials instead of fossil-based ones. 
• Calculation of the product carbon footprint of the first products and development of the first products with significantly lower PCF (cradle-to-gate).

Despite a 10% increase in sales, energy consumption was reduced by 9% and Scope 1 & 2 greenhouse gas emissions by 5%. These results underscore the company's commitment to climate protection and the continuous improvement of existing processes.

A particular milestone was the award of the silver medal by EcoVadis. This places WISKA among the top 8% of all companies assessed worldwide. 

“With the VSME report, we want to make visible what we stand for as a company: responsible action, measurable progress, and a willingness to continuously develop,” emphasizes Elske Kelm, Sustainability Officer at WISKA.  

“We are convinced that sustainability and economic success are not mutually exclusive, but rather mutually dependent,” adds Tanja Hoppmann. “With our first report in accordance with the VSME standard, we are making this claim visible.”

"It is a pleasure for us to see HSV in the 1. Bundesliga and to be able to be part of it. For us, this col-laboration is a strong sign of our connection to the north of Germany and our roots in Hamburg,‘ says Ronald Hoppmann, Managing Director of WISKA Hoppmann GmbH, which he runs together with his sister Tanja Hoppmann in the third generation. ’Many of our employees are loyal HSV fans who are enthusiastic about football and team sports. That's why we not only want to show our presence, but also create experiences: in the stadium, with our customers and for our employees and their families."

A clear commitment to Hamburg and the region
WISKA was founded in Hamburg in 1919 and is now firmly rooted in the north, with its headquarters in Kaltenkirchen. The partnership with HSV is an expression of this regional connection and the val-ues shared by both sides: team spirit, passion and consistency. For WISKA, this commitment is more than just sponsorship: it is an emotional commitment to Ham-burg, to the north of Germany and to the people who live and work here. ‘This partnership underlines our brand value of “ together”. Football is a team sport that brings people together – and that matches with our culture,’ adds Kristina Wilkens, Head of Marketing.

Outlook
As part of the partnership, plans include a presence at home games, events at the Volksparkstadion, competitions and joint content for the HSV and WISKA channels. In addition, WISKA also wants to offer employees and customers special experiences related to HSV – from free tickets to games to visiting the stadium together. As a family-oriented company, it is important to WISKA to involve not only its employees but also their families.

The Association of Technical Plastic Products honored the TriShot® ETKV 20, the first cable gland to be integrally manufactured using 3-component injection molding. The award was accepted by Dipl.-Ing. Peter Gehre, Head of Innovation & Development at WISKA, at the award ceremony.

"Since 1974, the TecPart Innovation Award has been awarded to outstanding and innovative technical products, modules and assemblies made of plastic. The expert jury evaluates

in particular, manufacturing finesse, plastic-compatible design and innovation in the component and process, such as the substitution of other materials," says the association.

About the TriShot®:

The TriShot® is the world's first cable gland to be used in 3-component injection molding. Their thoughtful design has helped to reduce material waste, energy consumption and assembly time, and to optimize production, while ensuring that the product meets the highest standards.

With an impressive 54.5% reduction in product carbon footprint compared to traditional cable glands, the TriShot® has an excellent sustainability record.

IP68 rating, built-in seal, excellent strain relief, large clamping range and short installation time are just some of the features that ensure the TriShot'®s performance in demanding conditions. Tested and inspected by a WISKA team of highly qualified designers and engineers at the WISKA Germany site.

"Our goal was clear from the very beginning: to develop a cable gland that excels in all areas – a product that meets the requirements of the future," explains Peter Gehre.

The management is also proud: "With its reduced CO₂ footprint, the TriShot® is part of the solution that we so urgently need to tackle climate change," emphasizes Tanja Hoppmann, Managing Director and Head of Sustainability at WISKA Hoppmann GmbH.

WISKA presents: the future of cable glands - TriShot®!
The TriShot ® is more than a cable gland, it is the result of continued drive to push boundries and possibilities. To be a pioneer and lead the way in 3 core principles: Innovation, Sustainability and Performance.
This cable gland is designed to perform. IP68 protection with or without cable/blind plug, quick installation, large clamping range (6 - 14 mm), built in seal, i.e. no inserts required and any cable type is sealed and with an impressive 54% reduction in product carbon footprint compared to conventional cable glands, the TriShot ® has an excellent sustainability performance.

Same quality, new origin: The WISKA KA series made from BIO-plastics!
The first product range from WISKA made from plastics that are no longer of fossil origin but are manufactured from renewable raw materials, so-called bioplastics. During their growth phase, the raw materials of these plastics absorb CO² and bind it throughout their utilisation phase. When our bioplastic products are used to generate energy at the end of their life cycle, they release only as much CO² as the plants used to make the raw material previously absorbed. The target is a closed CO² cycle that conserves limited resources.
