The AH164-ZTGE3 is a pilot light from Fuji Electric's Command Switches series, featuring an extended round lens design with a flat LED lamp operating at 24V DC. This device is configured with 1NO+1NC (one normally open and one normally closed) contact arrangement, providing visual indication in industrial control applications. The pilot light meets IP40 protection standards for standard types and is designed to withstand vibration and shock, eliminating lamp failure from mechanical stress. With a service life of approximately 1,000,000 operations and snap-action mechanism reliability, the AH164-ZTGE3 is suitable for use in machine tools, industrial machines, control panels, and distribution panels. The color lens can be easily changed using a small screwdriver, and the lettering on the legend sheet is back-lit for high visibility through the color lens.
