Nemesis mini-circular connectors are up to 50% lighterITT Interconnect Solutions has detailed its new range of Nemesis connectors for equipment used in integrated soldier systems in a new Applications Note. With some military personnel deployed in theatres of war required to carry in excess of 45kg of communications, vision and other equipment, reducing this weight is a priority for defence procurement agencies. ITT ICS Nemesis design engineers have succeeded in reducing both the weight and size of Nemesis mini circular connectors to deliver a lightweight, small plan form, ultra-rugged interconnect product line which is sealed for harsh environments and incorporates mission-critical innovations for future solider applications.

Claimed to be up to 50 per cent lighter and 60 per cent smaller than the nearest comparable 38999 connectors and sealed to IP67 or IP68, ITT ICS's new Nemesis range features stainless steel construction for added strength and durability. Profiles have been dramatically reduced, down to the 'no-profile' Space Saver variant for wearable equipment with 'Ripaway' extra-fast decoupling action. Nemesis connectors remain fully sealed in both mated and unmated conditions and have an enhanced strain relief design to eliminate cable overstressing and ensure the integrity of cable sealing. ITT ICS's canted spring technology enables snap-on/breakaway coupling and decoupling, which also allows effective and 'tuned' disconnect with 360-degree EMI shielding.

For operational ease, Nemesis connectors are designed to be blind mated. Ribbed rubber overmoulding provides a secure grip in wet or harsh environments. A salt spray-resistant anti-reflective finish makes Nemesis connectors especially suited to marine environments and helps to ensure soldiers remain concealed.

There are three Nemesis product lines for modern soldier equipment - Water Tight, fully sealed to IP68 (20m depth), with ITT ICS's micro-twist pin gold contacts guaranteeing in excess of 2500 mating cycles; Super Clean and High Mating, both sealed to IP67 and featuring ITT ICS's durable industry-leading pogo pin contacts, which provide over 10,000 mating cycles.

Plating options are RoHS-compliant black zinc nickel or electroless nickel for future-proofing customers' investment in the light of anticipated MIL standard revisions.

Applications include power, data and audio interconnect functions for GPS systems, vision systems, computers, batteries and radios.
