Datasheet Summary
Powered by GS/AI

The TE Connectivity SCHRACK SNRII PCB relay is a 5 mm-wide, general-purpose relay with a 1-form C (CO) contact rated for 6 A at 277 VAC, designed for PCB mounting in space-constrained applications. It features a reinforced insulation system, AgSnO2 contact material, and a sensitive coil operating at 170 mW with a 4.5 VDC coil voltage. The relay supports ambient temperatures up to 105 °C, has a mechanical endurance of 20 million operations, and meets EU RoHS, REACH, and UL VDE standards. It is available in flat-pack version with PCB-THT termination, weighs 5 g, and offers reinforced coil pins for DIN-rail socket compatibility. Insulation has a 4000 Vrms dielectric strength and 6.3 mm minimum creepage. Functional vibration and shock resistance are specified for both normally open and normally closed contacts.
