Datasheet Summary
Powered by GS/AI

The RY531 series is a general purpose miniature power PCB relay with a single-pole 8A contact rating and 1 form A (NO) contact arrangement. It has a low profile of 12.3mm height and is reflow-solderable with PCB-THT termination. The relay provides reinforced insulation with 5kV RMS dielectric strength between coil and contacts, 8mm clearance and creepage, and meets IEC 60335-1 for domestic appliances. Operating from a 12V DC coil with 627Ω resistance, it supports ambient temperatures from -40°C to +70°C and is classified as RTII flux-proof. The contact material is AgNi0.15, with maximum switching voltage of 400VAC and breaking capacity of 2000VA. Mechanical endurance is 30 million operations. Packaging is available in reels of 280 units.
