Datasheet Summary
Powered by GS/AI

The SR6-423-L012 is a force guided relay with 4 form A (NO) and 2 form B (NC) contacts, designed for safety circuits requiring diagnostic coverage of 99% per IEC 61508-2. It features AgSnO2 contact material and a monostable coil operating at 12VDC with 700mW power consumption. The relay supports a maximum switching voltage of 400VAC and a rated current of 8A, with a minimum recommended contact load of 5V/1mA. It provides reinforced isolation between all contacts and the coil, complying with IEC EN 62477. The 15.7mm height suits standard 22.5mm DIN rail housings. It meets VDE, TÜV, UL, and CCC safety approvals.
