Harwin adds female contact for Datamate connectors

Harwin has introduced a female contact for its Datamate connectors that enables significant increases in power delivery levels to be realised.

The T-Contact’s proprietary, six-finger design is machined from a single piece of beryllium copper. The contact raises the current capacity on compact 2mm pitch interconnection systems, with up to 8.5A per contact being supported. As a result, it further improves the size, weight and power (SWaP) parameters of the Datamate connector family, says Harwin and also addresses the growing need for engineers to increase power in modern, space-constrained designs.

The patented design employed in these components presents more contact points, enhancing their resilience to shock (100G) and vibrational forces (40G for six hours; two hours on each axis). The crimp barrels accept 22AWG wire and comply with IPC-A-620 cable harnessing specifications.

The contacts are also gold-plated in order to maintain reliable performance even in the most demanding of application environments, says Hawin, and allowing US military requirements to be met. It also means that a far greater number of mating cycles (up to 1,000) can be undertaken, extending the operation lifespan of connectors into which they are incorporated. Their operational temperature range spans from -55 to +125 degree C.

The T-Contact exhibits 60 per cent greater contact wipe compared to existing Datamate contacts – which improves the self-cleaning action and reduces the possibility of surface contamination arising.

Harwin also supplies a variety of dual-row housings with different jackscrews which are available direct from stock in a broad range of different sizes, from four to 50 position options.

 Target applications for the T-Contact are defence, avionics (control systems, radar, UAVs), motorsport (navigation systems, sensors, telemetry equipment), industrial automation (drives/controls, robotics, motion control systems) and satellites.

Harwin produces high reliability interconnect solutions that can deal with the most exacting of application demands – serving the defence, aerospace, space, industrial, oil/gas and motorsport sectors. Harwin’s global reach enables it to respond rapidly to customer needs, with sales offices and manufacturing facilities in the UK, the USA, Germany, France and Singapore.
