Omron, Twist Release, Emergency Stop Push Button Head 40 mm Diameter

This emergency stop push button head provides a user-accessible means to halt machinery in industrial settings, featuring an illuminated actuator for clear status indication. Designed for panel mounting, it offers a secure emergency intervention option where visible confirmation of button state is required and environmental protection is needed.

• Illuminated actuator gives clear operational indication
• Twist release actuation ensures intentional reset action
• Rated to IP65 to resist dust and water ingress
• Suits a 22mm panel aperture for straightforward replacement
• 40mm diameter button delivers large activation surface
• No hazardous-area certification simplifies non‑Ex installations

• Suitable for factory control panels requiring visual indication
• Ideal for machine tool emergency shutdown interfaces
• Used with conveyor systems needing splash‑resistant controls
• Can be used for retrofitting worn E‑stop heads on panels
• Appropriate for production lines where deliberate reset is required

The built‑in illumination provides a clearly visible indication of the switch state, improving operator recognition in dimly lit work areas.

The actuator uses a twist‑to‑release mechanism, so operators must rotate the head to restore the circuit and allow restart.

The IP65 rating means the head resists dust and low‑pressure water jets, permitting use in environments exposed to splash or wash‑down but not for full immersion.

Panels require a 22mm diameter cut‑out to accept the head, with sufficient clearance behind the aperture for mounting and wiring.
