Description
The SF2ER-E2R3B is a 22/25 mm panel-mount emergency stop button switch with a red mushroom-head actuator, featuring 2 normally-open and 3 normally-closed contacts in a safety-rated configuration. Designed for machine safety circuits, it meets IEC 60947-5-5 requirements for emergency stop devices. The positive-opening contact mechanism ensures contact separation under all conditions, and the latching mechanism maintains the stopped state until manually reset, preventing inadvertent machine restart.
