EN3 ? MINI WEATHERTIGHT OVERMOLDED CABLE ASSEMBLIES
243
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).
