SCM Interface – Connector series 30

This 19-pole connector from GISMA series 30 was developed for use in oil filled SCM or eSCM housings. With a contact diameter of 1.5 mm the max. permissible working voltage is 400 V DC, the max. working current is 15 A per contact. The creeping distances are designed acc. to DIN EN 60664-1 VDE 0110, pollution degree III. To ensure oil resistance FKM / Viton is used for sealing. In the cable connecting area boot seals are utilised as an additional sealing barrier.

Due to the robust design using materials like stainless steel and PEEK the maximum pressure load capacity is 350 bar.


New wet-pluggable connector

With the further development of our Series 10 underwater wet-pluggable insulators, we have designed a wet-pluggable silicone insulator in series 30 for an operating voltage of up to 400 V at a max. operating current of 15 A. Each contact is sealed with a water-displacing, conical elastomer sealing. In addition the elastic lip seal seals all contacts to the water. The double sealing system made of silicone elastomer guarantees high functional reliability in the temperature range from -40 °C to +80 °C. Together with a solid end housing, we offer our customers a solution for extremely harsh operating conditions.


Downhole connector

As part of a research project, we developed the new Series 30 hybrid connector made of duplex stainless steel for use in oil wells. Fiber-optic, electrical power contacts designed for 3 kV / 40A and hydraulic connecting elements are integrated in the filigree and robust stainless steel housing. The size-optimised connector is designed with temperature-resistant PEEK insulators and sealing elements for continuous operating temperatures of up to 180 °C and an operating pressure of max. 300 bar. A new type of endbell guarantees reliable sealing to the special high-temperature cable.


ArianeGroup Supplier Award

We feel honoured to have been presented with the 2017/18 ArianeGroup „Supplier Award for Master Performance“ and are thankful for the trusting, collaborative and fruitful partnership. We will continue to provide our customers with innovative products and a wide scope of expertise enabling them to successfully realise their projects.



For tow cables we offer customized solutions based on our series 10, 22 or 40. To achieve a higher contact density, elastomer insulators can be combined with solid contact inserts for fiber optic and electrical contacts. If operating voltages above 1000 V are required, high-voltage resistant silicone elastomers are available. For each cable, we develop the appropriate end housings and integrate strain relief elements made of aramid or steel. We can use the following housing materials for the demanding designs: Bronze CW307G, 1.4404, 1.4571, 1.3964, 1.4462, 1.4501 or 3.7164. We manufacture special connectors according to customer requirements and adapt the connector perfect to the specified installation dimensions.


New module connector for fiber optic and electrical contact inserts

With the new Series 42 we developed a compact, robust and inexpensive module connector for fiber optic and electrical contact inserts. With the proven contacts from our modular system, we offer maximum functional reliability with attractive installation dimensions. The shortened endbell provides an industrial connector for a wide range of applications. We are pleased to offer the series 42 also with pre-assembled cable.


New robust power connector

The new and extremely robust power connector of series 61 is designed for applications up to 100 m water depth. With the gold-plated 22 mm contact in a silicone insulator, a permanent operating current of 700 A at max. 1200 V can be transmitted. The excellent contact lamella guarantees low contact resistance over several hundred mating cycles and guarantees functional reliability over a very long period of use. Due to it’s solid construction, the connector is particularly suitable for harsh industrial conditions.


Plug series 40 size 4, 8 contacts with hose

This new 90° angeled high temperature resistant hybrid connector series 40 size 4 is assembled with FKM O-ring seals and designed for a maximum ambient temperature of 130 °C. The robust and smart 90° adapter allows an easy hose termination with the standardized MK II interface.
The connector can be assembled with fiber optic and two different electrical contact designs.


Series 10 power plug

This power plug series 10 size 6 has one socket contact with Ø 14 mm. It is designed for operating voltages of up to 3 kV AC and a maximum current of 250 A. A special feature is the insulator, which is made of silicone.


Series 22 special pressure hull penetrator

This not mateable series 22 pressure hull penetrator for battery charge connection is 90° angled at the outboard side and has a moulding endbell with elastomere-boot. It has a reinforced locking nut and profile sealing rings. The cable cross section is 240 mm².


Mounting frame for junction boxes and measuring equipment for installation at seabed.

This robust underwater frame was designed to install junction boxes and measuring equipment at the seabed. Flexible cable guides can be adjusted to different cable specifications. By installation of interchangeable counterbalance weights an individual centre of gravity compensation can be realised.


Series 34

The series 34 miniature connectors with robust titanium housing are ideal for harsh environments and underwater applications, also if small design dimensions are required.

Due to the compact dimensions, this series is optimal for small sensor housing. Special welded versions are available. Under advanced environmental conditions, the longitudinally watertight PEEK insulator guarantees high operational reliability.

With the double o-ring sealing in the mating area, high long-term performance is achieved for different applications.


Series 40 with flexible endbell

The combination of the series 40 special hybrid connectors with and a flexible endbell allows to reeldivided cable sets.

The low attenuation level is guarantee in motion and also under high tension load.


Opening ceremony

GISMA extends the production area by 1300 m². After almost one year of construction, the new production hall was officially opened. This created the basis for further growth. Many thanks to the city of Neumünster, the team of architects, craftsmen, service providers and our employees, who have contributed to make the project a success.


Series 64

The service plugs series 64 are designed for easy handling of the charging process of submarines. To cover a wide range of applications the modular pilot contacts are exchangeable. For an easier connecting operation of the eight power cables the connector is equipped with receptacles on the rear side. In addition the entire housing is made of insulating material to protect the operating persons.
