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 easily 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 94V-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.
* 2-8 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).
