Datasheet Summary
Powered by GS/AI

The ETPS4F2CD is a hermetically sealed 4PDT electromechanical relay with a welded non-corrosive enclosure, designed for rail and aerospace applications. It measures 26.0 x 26.0 x 25.7 mm and weighs 77 grams. The device operates across a temperature range of -70°C to +125°C, with a maximum contact bounce time of 1 ms and a mechanical life of up to 500,000 cycles. It features a 36 Vdc coil with a resistance of 550 Ω ±10% at +25°C and includes internal voltage suppression. The relay supports a nominal contact rating of 1.5 A at 37.5 Vdc for inductive loads over 2,000 cycles and 0.6 A at 74 Vdc. Its dielectric strength is 1,000 Vrms between coil and case, with an initial insulation resistance of 100 MΩ min at 500 Vdc. Terminal plating is tin, and mounting is code 3 with #4-40 UNC threads.
