Datasheet Summary
Powered by GS/AI

The E405 is a hermetically sealed 4PDT electromagnetic relay rated for 5 A switching, designed for severe environment applications in aerospace, defense, and rail systems. It has a rectangular package measuring 20.6 mm × 20.6 mm × 16.3 mm and weighs up to 26.4 grams. The relay operates from -70°C to +125°C, withstands up to 200g shock and 30g vibration, and meets MIL-PRF-83536. Contact voltage drop is 150 mV initial and 175 mV after life testing. Coil variants include 12 VDC, with a resistance of 72 Ω ±10% at +25°C. The relay has 6 ms maximum operate and release times and 1 ms bounce time. Dielectric strength is 1,000 Vrms between coil and case for non-Mounting Code 5 variants. Insulation resistance is 100 MΩ minimum initially and 50 MΩ after life testing.
