EN3 MINI WEATHERTIGHT CONNECTOR SERIES GENERAL FEATURES AND BENEFITS * Great all-purpose connector weather or not sealing feature is required. * Superior leakage protection. Contact area is double-sealed for excellent moisture and chemical resistance when mated to Switchcraft's connectors. * Integral O-ring and gasket. O-ring is molded onto cord housing assembly and gasket is molded onto panel housing assembly to prevent leakage and eliminate need for additional O-rings and gaskets. * Reduced part count for reduced labor to assemble. * No Grommets. Cable clamp assembly features living hinges, which snap a onto and support the cable. * Thermoplastic rubber body simulates closed entry contact system to prevent probe damage or accidental loss of spring retention due to misaligned or bent pins. * Abrasion-resistant thermoplastic boot provides strain relief and accepts cable diameter .195" to .265". * Housing rated UL 94\-O against flammability. * Panel connector shell features a positioning keyway to prevent misalignments and a polarizing single D design for proper panel mounting and to prevent rotational movement. 2-18 pins. * Exceeds Coast Guard specifications for water tightness (CFR 46 Part 110.20). * Optional cap covers panel housing assembly when not in use. * Exceeds enclosure rating IP16/IP18 when not mated or covered and IP66/IP68 when mated or covered (IEC 529). * Exceeds enclosure rating 6P at 1000V when mated or covered (NEMA 250). MATING INSTRUCTIONS FOR A CORD CONNECTOR TO A PANEL MOUNT OR IN-LINE CONNECTOR First, align the notched keyway on both the panel mount or in-line and cord connector. Then, push the cord connector onto the mating connector. Grasp the coupling ring between the slots, push it toward the panel mount connector and rotate it clockwise nearly one half a turn. Continue rotating until you feel the coupling ring ride over the locking bump. This is the locked position. The cord connector is not securely in place unless this procedure is followed.
