Datasheet
Datasheet Summary
Powered by GS/AI

The SR6-426-L012-0V is a force-guided relay with six contacts arranged as four normally open and two normally closed, designed for safety-critical applications requiring 99% diagnostic coverage per IEC 61508-2. It features a monostable coil rated at 12VDC with 700mW power consumption and AgSnO2 contacts plated with gold for low-level signal monitoring down to 5V/1mA. The relay has a height of 15.7mm, rated for switching up to 400VAC and 8A, and meets reinforced isolation standards per IEC EN 62477 between all contacts. It complies with VDE, TÜV, UL, and CCC approvals and operates reliably up to 85°C ambient temperature. The part uses solder pins for termination and fits within 22.5mm DIN rail housings.
