Omron A22E Series Turn Reset Emergency Stop Push Button Panel Mount 22 mm Cutout 2 NC IP65 A22E-L-02

Omron A22E-L-02 emergency stop push button is a robust panel mount safety switch featuring a 22 mm panel cutout and a red, round mushroom-type push button head measuring 60 mm in diameter. This switch is actuated by a turn-reset mechanism, which requires the operator to rotate the button to reset it manually. It includes two normally closed (2 NC) contacts rated for 10A at 380V AC and DC, suitable for interrupting medium-power electrical circuits in industrial automation environments.

The push button switch is designed for installation in industrial control panels and machinery where emergency shutdown functionality is required. Its screw terminal connections accommodate round or fork crimped wires secured by M3.5 screws to ensure reliable electrical connections. The unit complies with CE and cULus certifications, meeting safety requirements for direct-opening mechanisms used in emergency stop equipment.

This device provides an IP65 front protection rating, making it resistant to dust ingress and splashing water, suitable for typical factory indoor environments. It supports panel cutouts of 22 mm diameter, expandable to 25 mm when using an optional ring; however, IP69K variants are not compatible with larger rings.

The emergency stop button is ideal for use in assembly lines, conveyor systems, manufacturing process control, and other automated industrial systems where rapid and reliable machine stoppage is paramount to safety. Its durable plastic push button and turn-reset action minimize accidental restarts while ensuring rapid disengagement.

Key technical features include 10A contact ratings, 380V AC/DC voltage handling, two normally closed contact configuration, and compliance with UL508, EN60947, GB14048.5, and other international standards. This product is manufactured in Japan to high-quality standards and intended for indoor environments with an ambient temperature operating range from -20°C to +70°C depending on model configuration.

The push button uses a turn-reset mechanism to prevent unintentional reactivation. Red mushroom head offers clear visual indication of emergency stop status. IP65 rating protects against dust and water ingress in industrial settings.

Two normally closed contacts ensure positive circuit interruption. Compatible with 22 mm panel cutouts, with optional 25 mm ring insert available. Screw terminal connection facilitates secure wiring installations. Certified to recognized safety standards including CE and cULus.
