About this manual

The GP250 is a polarized, latching hermetically sealed relay with a 2 A / 50 Vdc contact rating. It is compact (20.4 mm × 10.4 mm × 10.2 mm), lightweight (11 g max), and operates over a wide temperature range from –65 °C to +125 °C.

The data sheet details coil characteristics for 6 V, 12 V and 26 V versions, mounting styles, terminal types, and includes application notes on coil suppression techniques, bifilar coils, and diode‑resistor networks to control surge voltage and contact speed.
