Since 1983 GISMA Steckverbinder GmbH has specialised in the development, design and production of underwater connectors. As an independant company managed by its owner, GISMA belongs world-wide to one of the market leaders in the industry.

The high-quality electrical and fibre-optical connectors are mainly used in the offshore industry, the ocean and marine technology. The range of products covers more than 5500 different connectors in 18 series – and the development constantly continues.

GISMA manufactures special products for the offshore industry which are designed for continuously increasing water depths which can easily be operated by ROVs. New systems for energy generation out of the ocean offer future markets for GISMA. With the completion of our new manufacturing facility in 2009, we reached a further milestone of our company history.

GISMA’s success is based on:

  • A high quality management system with DIN ISO 9001 (DNV) approval.
  • Consistency in meeting the needs of the customers.
  • Short, reliable delivery times.
  • Wide range of services from advising individual customers to delivering fully tested, terminated cable assemblies.
  • High competence in design, construction, production and marketing.

Thousands of GISMA connectors are used worldwide in numerous submarines, offshore and pump industry applications as well as in the research. Even special orders are carried out quickly and efficiently by GISMA’s own computeraided design department, tooling and ultramodern computer controlled machines for production.

GISMA offers an extensive family of standard connectors with contact numbers from 1-265, working voltages up to 12 kV AC and current ratings up to 1000 A for deep sea application down to 10000 metres. All types of optical fibres, single and multimode, can be assembled with GISMA connectors. Certificates of approval from well known test organisations, i. e. GL – German Lloyd and DNV – Det Norske Veritas are available.
