Omron A22NE Series Twist Release Emergency Stop Push Button, Panel Mount, 22 mm Cutout, 1 NC, IP65

This emergency stop push button provides a manually operated means to halt machinery and processes in industrial panel-mounted installations. Designed for front-panel fitting, it offers a straightforward, red, round actuator for clear identification and rapid intervention in control systems operating at low voltages.

• IP65 sealing prevents ingress in dusty or wet environments
• Panel mount configuration enables secure front-panel installation
• 22mm cut-out requirement simplifies panel modification
• Single normally closed safety contact ensures circuit interruption
• Twist-release actuation allows reset only by deliberate action
• Compatible with 24V AC/DC control circuits for low-voltage systems

• Suitable for emergency shut-off on production machinery
• Ideal for control panels in wet or dusty locations
• Used with 24V control circuits in automation cabinets
• Can be used for safety isolation on conveyor controls
• Suitable for retrofit in existing 22mm panel openings

It employs one normally closed contact which opens when actuated, interrupting the control loop to stop equipment.

The actuator uses a twist-to-release mechanism requiring a deliberate rotary action to return the button to its ready position.

The enclosure is rated IP65, offering protection against dust ingress and low-pressure water jets onto the enclosure.

The contact is specified for operation on 24V in both alternating and direct current systems.
