WEATHERTIGHT CONNECTORS PRODUCT BULLETIN 541 EN3TM Series 9-18 Pins Switchcraft expands the EN3TM Series up to 18 pins. The EN3TM Series is a popular plastic connector series that meets a number of harsh weather environmental ratings. It's now available from 2 through 18 pins. The 9-18 pin versions are only available with solder terminals. The solder terminals come in two styles, straight or staggered. The straight style has equal length terminals, all facing the same way. The staggered version has the inner set of terminals longer than the outer set. Also, the staggered terminals face radially away from the center of the connector, to make soldering much easier. The 9-18 versions carry the same environmental ratings as the 2-8, which include IP66/IP68 and NEMA 250, when mated. Features and Benefits * Available in solder terminals only, either straight or staggered for easier soldering * Exceeds enclosure rating IP16/IP18 when not mated or covered, IP66/IP68 when mated * Exceeds Coast Guard specifications for water tightness (CFR 46 Part 110.20) * UL 94V-O rated material * Gold-plated pins and contacts to reduce contact resistance Specifications EN3P18M26S Materials Panel connector shells and contact locking disk: Thermoplastic polymer glass fiber, flame retardant Connector shell interior: Thermoplastic rubber Contacts: Copper base alloy gold-plated over nickel underplate Mechanical Shock: Mil-Std 202 Method 213B, condition K Vibration: Mil-Std 202 Method 201 Life: 600 insertion/withdrawal cycles (minimum) Electrical Voltage Rating (sea level): Tested at 600 VRMS Insulation Resistance: 100 megohms (minimum) at 77 F Contact Resistance: 5 milliohms (maximum) Current Rating: 3.0 Amps (#26 contact) Continued EN3C18F26 2 WEATHERTIGHT CONNECTORS PRODUCT BULLETIN 541 Specifications continued Environmental Temperature Limits: -40C to +65C (non-operating) Moisture Resistance: Mil-Std 202 Method 106F Insulation Resistance: Mil-Std 202 Method 302 condition B Thermal Shock: Mil-Std 202 Method 107G Salt Spray: Mil-Std 202 Method 101D condition B Ratings IP16/IP18 IP66/IP68 NEMA 250 (6P) CFR 46 Part 110.20 UL 94V-O Ordering information EN3 ___ ___ ___ ___ 26 ___ ____ Series Connector Type P - Panel C - Cord # of Pins/Contacts 9-18 Contact Style S - Stagger Solder Leave Blank for Straight Solder Contact Size 26 - #26 Gender M - Male F - Female See Engineering Design Guide or website for details on the complete EN3 product line.
