The ER412DM4-26A is a high-reliability, non-latching DPDT relay in a hermetically sealed TO-5 package, featuring an internal diode for coil transient suppression. It operates on a nominal coil voltage of 26.5 Vdc with a maximum pickup voltage of 18.0 Vdc and has a coil resistance of 1560 ohms. The relay's 2 Form C (DPDT) contacts are rated for DC resistive loads up to 1 A at 28 Vdc and it is designed for continuous duty across a wide operating temperature range of –65°C to +125°C. With its all-welded construction, high resistance to shock (75 g's) and vibration (30 g's), this relay ensures reliable performance in harsh environments. Its ultraminiature size makes it ideal for high-density PC board applications, including low-level and RF switching.
