Nicomatic’s solution follows MIL-STD-83513 performance standards, meets the constraints of severe temperature environments, and can be waterproof if necessary. In terms of wiring, Nicomatic has received an “A” rating from Thales and complies with EN9100 and ISO9001 standards.

Axon’ Cable manufactures overmolded assemblies for any market. Axon’ Cable manufactures overmolded assemblies for any market. Axon’ overmolding provides robust and tailor-made mechanical protection, particularly for the cable/connector interface, which is traditionally the weakest point of cable assemblies. The experts at Axon’ can assist with designing the ideal solution for your needs by addressing a number of key considerations, including space-saving with custom shapes, strain relief, sealing (airtightness, watertightness), absorption of repeated flexes, provision of fixing points, protection of shielding termination (EMC), improvement of the overall look of the harness, integration of links or parts into the customer’s system, customized contact overmolding for higher performance compared to a standardized connector, integration of electronic functions (e.g. signal conversion) in cable assemblies, and customized interconnect solutions.
