일반적인 용도
Japanese-standard e-stop for Fuji automation panels. Found on FANUC-controlled CNC machines alongside Fuji drives.
Research Notes
1. Overview
The Fuji Electric AR22V2R-10R is a 22 mm red mushroom-head emergency-stop pushbutton from Fuji's AR22 series — a Ø40 red mushroom, push-to-stop / twist-to-release, with a 1 NC contact (the safety contact that opens on actuation). It's a complete command device (JIS Japanese standard, also UL/CE). Red mushroom + latching (twist-release) + NC is the standard E-STOP configuration for machine safety circuits.
2. User Sentiment
Fuji AR22 e-stops are a standard, reliable choice in Fuji/Japanese-standard control gear — robust, clearly-marked (red on yellow where a legend plate is used), and easy to reset by twist. As a safety device the key considerations are the contact configuration (1 NC here — add a second NC or a monitoring contact if the safety circuit/category requires), the release method (twist), and meeting the required safety category/standard.
3. Real-World Applications
Machine and process emergency stop — press the red mushroom to latch/stop (opening the NC contact), twist to release/reset. Mounted where an operator needs an accessible E-STOP (machine sides, control desks, pendants).
4. Technical Specifications
- Type: Fuji AR22 emergency-stop mushroom pushbutton, 22 mm
- Actuator: red Ø40 mushroom, push-to-latch, twist-to-release
- Contact: 1 NC (safety/stop)
- Cutout: 22 mm
- Sealing: IP65 (series)
- Approvals: JIS, UL, CE
5. Ordering & Compatibility
Fits standard 22 mm cutouts. For a monitored/redundant safety circuit, a single NC may be insufficient — spec the correct contact configuration and safety category (add contact blocks as needed). Pairs with a yellow legend/backing plate for standard E-STOP presentation. Confirm the exact code (color, release method, contacts).
6. Known Issues
No notable reliability issues — a mainstream Fuji safety device. Practical care: for safety duty verify the contact configuration and safety category/standard, ensure the twist-release and mounting suit the application, and use the correct legend/backing for clear E-STOP identification.

설치 빠른 참조
Panel cutout: 22mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).
Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.
Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.

문제 해결
E-stop won't reset (twist/pull doesn't release)
Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.
Machine doesn't stop when e-stop is pressed
Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.
Safety relay faults after e-stop reset
The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
