Designed for field wiring of sensing devices, this family of 8-mm, watertight circular connectors employs a patented penetration technique that eliminates the need for screwing, soldering or crimping- to assemble the connectors, users simply feed through the cable, insert the wire, and tighten the nuts.The connectors are available with 3 or 4 poles, in a straight configuration or with an angled socket, as well as with LEDs for indicating operating conditions.
