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