An emergency stop button (E-stop) is an essential manual safeguard in machine safety design. The AR22V2L is a 22 mm emergency stop button from the Fuji Electric AR series, with a 40 mm mushroom head and LED illumination (DC24 V). The AH165-2VR11 is from the compact 16 mm series and uses the same push-lock, turn-reset operation, for control panels with less mounting space. Both comply with UL / CSA / TÜV / EN60947.
Both use push-lock, turn-reset operation in line with the EN ISO 13850 emergency stop requirements.

About the AR22V2L illumination
The AR22V2L has an E3 LED illumination unit with a DC24 V coil voltage. An illuminated E-stop serves two purposes in a control panel: it makes the E-stop easier to find at night or in low light so it can be located quickly in an emergency, and the LED can show whether the machine is powered or running, helping judge whether maintenance is safe to start.
