Molded in a 94 V-0 rated, glass filled PBT resin, the polarized LEA Series housings incorporate a positive locking feature preventing accidental disconnection due to routing of wires or vibration. This series is available in two circuits only. The positive lock provides an audible click and is felt when mating the housing assembly with the mating header. The housing is notched on one side for ease of locating the pin 1 position.
