Omron A22-FR-01M — A22 Red Flush Push Button (1NC)

Red flush momentary push button, Omron A22 series. 22mm cutout, IP65, with 1NC contact.

Ứng Dụng Phổ Biến

Red stop button from the Omron A22 series. Standard on Omron-controlled production lines in electronics manufacturing, food packaging, and semiconductor handling equipment. The 1NC contact breaks the circuit on press. In Japanese and Korean factories, Omron buttons are the default choice — if you are maintaining imported Japanese machinery, this is likely what you will find on the control panel.

Hướng Dẫn Cài Đặt Nhanh

Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).

Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.

Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Khắc phục sự cố

Button doesn't respond when pressed

Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.

Works intermittently

Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.

Button feels mushy or doesn't click

The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
