EN3™ MINI WEATHERTIGHT
OVERMOLDED CABLE ASSEMBLIES

FEATURES AND BENEFITS

• Dual purpose handle provides flex relief and finger grip design for easy insertion and withdrawal.
• Available in both cord and in-line versions.
• 2 through 8 pin configurations.
• Superior leakage protection. Contact area is double-sealed for excellent moisture and chemical resistance.
• 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 copper case o-rings and gaskets.
• Thermoplastic rubber body simulates closed entry contact system to prevent probe damage or accidental loss of spring retention due to misaligned or bent pins.
• Housing rated UL 94V-O against flammability.
• Exceeds Coast Guard specifications for water tightness (CFR 46 Part 110.20).
• 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).
