Datasheet Summary
Powered by GS/AI

The ES110B3ED is a hermetically sealed 1PDT electromechanical relay rated for 10 A switching, designed for severe-environment applications in aerospace, rail, and ground vehicle systems. It measures 20.6 mm × 10.4 mm × 16.3 mm and weighs 17 grams. The device operates with a 12 Vdc coil, has a maximum coil resistance of 90 Ω at +25°C, and meets MIL-PRF-83536 requirements. It supports a temperature range of -70°C to +125°C, withstands 30g sinusoidal vibration, and handles 200g shock (except Mounting Code 3 at 100g). Contact dielectric strength is 1,250 V rms at sea level initially, and 1,000 V rms after life testing. Operate and release times are both 6 ms max at 25°C. The part includes internal voltage suppression and features tin-plated terminals with mounting code 3.
