Compact Inductive Proximity Sensor GA-311/GH

With a 3.3kHz response frequency, the GH Series Inductive Proximity Sensors are ideally suited for applications that require sensing of high-speed moving objects. These Proximity Sensors have the same form factor as Panasonic’s FX-300 Series Fiber Sensors and use the same shape quick-connection cables which, when used together, require minimal mounting space, but more importantly less power and wiring.
