The GX-H series cylindrical Inductive Proximity Sensor with amplifier built-in. The sensor features improved performance, environmental resistance and operability. As the enclosure is entirely coated by fluorine resin, the sensor can be safely used at a place where welding spatters fly around. Both the pigtail cable and the mating cable are also spatter-resistant. As the sensor can be securely tightened, it does not get loose due to vibration or shock.
