A comprehensive range of backshells with a rugged aluminium alloy construction and electroless nickel plating can be applied to new connector installations or alternatively for carrying out mid production modifications. Developed by Harwin for wire-to-board connectors, the metal shells make connectors more mechanically robust and provide EMI/RFI protection.

Incorporated into the female cable versions is a highly convenient attachment feature via which braid screening can be achieved. There is a large elliptical entry hole for braid placement, along with a choice of slotted or hexagonal jackscrews on either side for securing the connection (as well as providing strain relief). The male backshell is designed for panel mount applications and is compatible with both cable or vertical PCB connector styles. Full 360° EMI/RFI shielding is delivered once the male/female mating process has been completed. Working temperature range spans -55 to +125°C.

The new Harwin backshells can be used in conjunction with both the company’s J-Tek and its Mix-Tek Datamate connector product lines – with signal, power and coax cabling all accommodated. The combined Datamate/backshell assemblies are significantly lower in overall cost than equivalent Micro-D/backshell arrangements. Made to order, only low minimum volumes are required and there are very short turnaround times involved. Among the key areas where these items will be employed are aerospace, motorsport, industrial drives/controls, military communication, satellite systems, robotics and renewable energy infrastructure.
