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
Switccraft’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).
