Teledyne Impulse-PDM, is a distributor of underwater electrical connectors, cables, harnesses, and cable assemblies for the UK and European subsea market. We also offer a broad range of quality engineering services, including the Quickcure Molding System and related polyurethane materials.

DESIGN – our engineers design bespoke subsea connector and cable solutions for harsh environments, including military connectors and assemblies used on the T45 and Astute naval programs.

MANUFACTURE – wiring, encapsulation, and molding of underwater cables and harnesses. We manufacture the Omicron and Omega underwater fiber optic connectors.

TEST – We perform the following in-house testing of manufactured products, as required:

  1. - Insulation
  2. - Resistance
  3. - Capacitance
  4. - Inductance
  5. - Fiber optical signal loss testing
  6. - Dimensional inspection

PROJECT MANAGEMENT - The company provides total solutions to customers' connector, cable assembly and connectivity projects. Teledyne Impulse-PDM engineers will design, manufacture and test to prototype to ensure the final product supplied meets each project's specifications. 

 
The design engineering team can draw upon experiences ranging from atmospheric diving; remotely operated vehicles; deep sea photographic camera systems; bespoke housings for video cameras and instrumentation, to oceanographic sampling equipment. The engineers have also acquired diverse manufacturing skills and knowledge of hydraulics, pneumatics and injection molding.
