Omron A22NE-PD Series Twist Release Illuminated Emergency Stop Push Button, Panel Mount, 22 mm Cutout, 2 NC, IP65

This emergency stop push button provides a visible, lockable means to interrupt machinery power and halt operations in production and control environments. Designed for panel mounting with a 22mm cut-out, it incorporates an illuminated red mushroom head for clear identification and a turn-to-reset mechanism to prevent accidental restarts. The unit is suitable for industrial control panels where tactile, easily accessible emergency actuation is required.

• 2NC contacts deliver positive safety switching for stop circuits
• 5A contact rating supports moderate load interruption at 250V
• IP65 enclosure resists dust ingress and water jets
• 40mm mushroom head improves Rapid manual activation
• Push-In Plus terminals enable fast, secure electrical connection
• Turn-to-reset action prevents inadvertent restart after actuation

• Suitable for automated assembly line emergency shutdowns
• Ideal for control panels on machine tools and presses
• Used with conveyor systems requiring immediate stop function
• Can be used for safety stations in robotics workcells
• Used for machinery where illuminated status indication is needed

It is rated to switch up to 250V for both AC and DC applications, enabling use across common industrial supply arrangements.

The built-in illumination improves visibility of the stop control in low-light panels and indicates presence of the control regardless of ambient lighting.

The actuating head requires a clockwise turn to release the latch and allow the control to return to its ready state.

The switch offers a mixed contact arrangement with one normally open and one normally closed contact to support monitoring and circuit interruption schemes.
