3.00mm pitch connectors and cable assemblies set benchmarks in power delivery
Claimed to set new benchmarks in power delivery in harsh, demanding environments, the M300 family from Harwin comprises robust cable-to-board, board-to-board and cable-to-cable power connectors. Available in three-, six- and 10-contact formats, the parts can be accompanied by a variety of cable assembly options (with lengths from 150 to 450mm supplied).
The patented four-finger contact design relies on a beryllium copper alloy construction to maintain connection integrity – even when these connectors are subjected to high degrees of shock, vibration, or other forms of mechanical stress, says Harwin.
The narrow pitch connectors have a 10A current rating, and are therefore optimised for use in systems where the performance expectations are exacting, but space constraints also need to be addressed.
A combination of stainless steel jackscrews ensures secure mating. Connectors have a mating cycle durability of 1000 mating/un-mating operations. A series of polarisation mechanisms prevent mis-mating, which includes the recessed ‘scoop-proof’ female contacts, while shrouded housing arrangement for the male contacts help protect them from sources of potential damage and a back potted rear aids cable retention.
The M300 series is halogen-free and RoHS-compliant and target motorsport, defence, factory automation, satellite, robotics, renewable energy and avionics projects. An extensive working temperature range is supported (spanning from -65 to +175 degrees C) and low outgassing properties contribute to performance when the connectors are deployed within a vacuum.
Harwin produces high reliability interconnect solutions for the most exacting of application demands, i.e. defence, aerospace, space, industrial, oil/gas and motorsport sectors. Over the course of the last 65 years, the company has continued to set new benchmarks in terms of innovation, automation and service, through ongoing investment in advanced equipment and the training of its staff. Skilled engineers have developed an array of ‘must not fail’ connector products, including the Gecko (1.25mm pitch), Datamate (2mm pitch), Mix-Tek (combined signal, power and coax) and high temperature M300 (3mm pitch) product lines. In addition, Harwin offers EMI/RFI shielding, a comprehensive portfolio of PCB hardware (spacers, links, bridges, terminals, test points) and a broad range of industry standard connectors.
