Schneider Electric XB6AS9349B Emergency Stop Red Mushroom Trigger Latching Key Emergency Stop Push Button

The Schneider Electric XB6AS9349B is a Harmony XB6 complete emergency stop push button with a red mushroom head, 30 mm diameter, on a 16 mm plastic bezel body. Trigger-action mechanical latching holds the button in once pressed, releasing only with a Ronis No. 200 key, and it carries 1NO+2NC slow-break contacts for safety-circuit wiring.

Selection Notes

Key release restricts who can restart the machine after an emergency stop: only a holder of the Ronis No. 200 key can turn and withdraw it to reset, unlike the turn-to-release XB6AS8349B, which anyone can reset by hand. This suits lockout-style procedures where a supervisor controls restart authority. The 1NO+2NC contact set gives two positively-opened NC paths for redundant safety-relay monitoring plus one NO auxiliary for status feedback. The 30 mm mushroom head stands proud of the 16 mm bezel for fast actuation under stress, per ISO 13850.
