Omron A22NE Series, Turn Reset, Emergency Stop Push Button Head 40 mm Diameter

This emergency stop push-button head provides a manual means to halt machinery and processes in industrial control panels. Designed for panel mounting, it is a non‑illuminated, IP65‑rated stop head intended for use where an immediately accessible, Durable E‑stop Interface is required. The device employs a turn‑to‑reset actuation suitable for systems that need a deliberate reset action after an emergency stop.

• IP65 enclosure resists dust and water ingress
• Non‑illuminated design reduces electrical complexity

The head is intended to fit a 22mm panel cut‑out, ensuring compatibility with common industrial control panel openings.

The turn‑to‑reset action requires a deliberate rotary operation to release the latch, reducing the chance of inadvertent restart after an emergency stop.

With an IP65 rating it is protected against dust ingress and low‑pressure water jets, making it appropriate for dusty areas and light wash‑down conditions.

No internal illumination is provided, so it relies on ambient or panel lighting for visibility during operation.
