02A312HC2-0030 is a DC relay designed for demanding aerospace and military applications. It features a coil resistance of 300 ohms ±10% at 25°C, with a nominal voltage of 28.0 VDC, must operate voltage of 13.0 VDC, and must release voltage between 1.6 VDC minimum and 7.0 VDC maximum. The relay offers robust contact ratings of 10 amps at 28 VDC and 100 amps at 115 VAC 400 Hz resistive. Environmental specifications include an operating temperature range of -70°C to +125°C, vibration resistance from 10 cps to 2000 cps at 20 g's, and shock resistance of 50 g's at 11 ms duration. With fast operate and release times of 10 ms maximum and minimal contact bounce, this relay is suitable for high-reliability communication and instrumentation systems.
