Comus International Relays, Hg Wet Relays GUP.40005

Miniature mercury wetted reed relay with two form A contacts, designed for PCB mounting and fully encapsulated in a plastic case. The relay operates at a nominal coil voltage of 20 V with a coil resistance of 900 ohms, has a maximum switching voltage of 500 V DC/AC, a maximum switching current of 2 A, and a maximum carry current of 3 A. Contact resistance is 70 mOhm at 50 mV and 10 mA. It offers a minimum life expectancy of 1 × 10^9 operations at 1 V and 10 mA. Operate and release times are 2.0 ms under nominal coil voltage and Zener-diode suppression. Operating temperature ranges from -10 °C to 85 °C, and storage temperature from -40 °C to 105 °C. Shock resistance is 30 g for a 11 ms half-sine pulse, and vibration resistance is 10 g from 10 to 500 Hz.
