The ER432DM-12A is a sensitive, established reliability DPDT relay in a hermetically sealed TO-5 package, designed for high-density PC board mounting. This model operates with a nominal coil voltage of 12.0 Vdc and features an 850 Ohm coil, resulting in low operating power of approximately 200 milliwatts. It includes an internal silicon diode for coil transient suppression and is rated for DC resistive contact loads of 1 Amp at 28Vdc. Due to its small size, low power dissipation, and inherently low intercontact capacitance, the ER432DM-12A is a versatile and highly reliable solution for applications ranging from low-level signal switching to RF switching.
