The ER412M4-26A/G is a DPDT non-latching, established reliability relay housed in a hermetically sealed TO-5 package. It operates on a nominal coil voltage of 26.5 Vdc with a maximum pick-up voltage of 18.0 Vdc and a coil resistance of 1560 Ohms. This ultraminiature relay provides a DC resistive contact rating of 1 A at 28 Vdc, with a maximum operate time of 2.0 ms and a maximum release time of 1.5 ms. Its all-welded construction, high shock and vibration resistance, and wide operating temperature range of -65°C to +125°C ensure high reliability in harsh environments. Due to its small size, low coil power dissipation, and good RF characteristics, it is ideal for high-density PCB applications, including T-R switching in radio transceivers.
