Tin-plated blade pin contacts and a latch lock fastening make this a free-hanging (in-line) connector suited for internal harnesses where the connector will be mated infrequently — the tin finish handles a few dozen cycles, not hundreds. The natural colour housing and dual wire exit feature simplify routing in tight enclosures.
The blade pin contacts mate with a matching Mark II header (sold separately). The dual wire exit allows the cable to leave the connector from either side, which helps when routing around obstacles.
