Omron A22-FY-10M — A22 Yellow Flush Push Button (1NO)

Yellow flush momentary push button, Omron A22 series. 22mm cutout, IP65, with 1NO contact. Screw terminals.

Common Applications

Yellow push button from the Omron A22 series used for intervention functions — fault reset, alarm acknowledgement, and jam-clear operations per IEC 60204-1 color standards. Found on Omron-controlled packaging machines, electronics assembly lines, and food processing equipment built by Japanese and Asian machine builders. The 1NO contact is typically wired to an Omron CJ/NJ PLC input for fault-reset logic. Note the narrower operating temperature range (-10 to 55 degrees C) compared to European brands — suitable for indoor factory environments but not cold storage. Pairs with the A22-FG-10M (green) and A22-FR-01M (red).

Specifications

Actuator Shape The physical shape of the pressable surface.	Round
Actuator Type The button head style. Flush sits level with the bezel (prevents accidental presses). Extended protrudes for easy access.	Flush
Certifications Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.	UL, CSA, CE
Color Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).	Yellow
Contact Configuration Normally Open — circuit is off until you press. Standard for start/go/enable functions.	1NO
Cutout Diameter The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.	22mm
IP Rating IP65: Dust-tight and protected against low-pressure water jets. Suitable for indoor industrial and light washdown.	IP65
Material The bezel/body material. Metal bezels are more durable in harsh environments. Plastic is lighter and cheaper.	Plastic
Mounting Type How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.	Panel
Max Operating Temp Highest temperature the button is rated to operate in.	55°C
Min Operating Temp Lowest temperature the button is rated to operate in.	-10°C
Terminal Type How you connect wires. Screw clamp is most common in industrial. Spring cage is faster but requires proper ferrules.	Screw

Installation Quick Reference

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.

Wiring Diagram

Troubleshooting

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.
