Omron A22NE-PD Series Twist Release Emergency Stop Push Button, Panel Mount, 22 mm Cutout, 2 NO/2 NC, IP69K, IP65

This emergency stop push button is a manually operated safety device designed to interrupt machinery control circuits in industrial settings. It provides a clear, immediately recognisable stop actuator in a Compact panel-mounted format and is intended for installation where quick shutdown and reset are required. The unit is non-illuminated and suited to environments needing ingress protection against dust and water.

• Red actuator provides Rapid Visual identification and quick response
• 2NC1NO contact arrangement allows safety and auxiliary circuits
• IP65 sealing ensures continued operation in dusty or wet conditions
• Turn-reset mechanism prevents accidental re-engagement after stop
• Push-in terminals enable fast wiring and secure connections
• Panel-mount design simplifies integration into control panels

• Suitable for factory automation emergency shutdowns on assembly lines
• Ideal for electrical control cabinets requiring a local stop control
• Used with conveyor systems to provide operator access to stop function
• Can be used for machine tool safety isolation in workshops
• Used for mechanical press stations where a manual halt is required

It uses push-in Terminal technology that accepts conductors directly, reducing wiring time and ensuring a firm contact retention suitable for industrial installations.

The operator must perform a turn-reset action on the mushroom head to restore the actuator to its normal position before the circuit can be re-enabled.

The housing is rated to IP65, offering protection against ingress of dust and low-pressure water jets, suitable for many shop-floor conditions.

The contact configuration provides two normally closed contacts for safety circuits and one normally open contact for auxiliary signalling or interlocks.

The assembly requires an overall depth of 87mm behind the mounting face for proper installation.
