DC 3-wire Cylindrical Inductive Proximity Sensor Amplifier Built-in Oil resistant Metal embedding possible GXL INDUCTIVE PROXIMITY SENSORS GX-N SERIES GX-U/FU GL-18H/18HL GL-N12 Amplifier Built-in GL-8/8U GL-6 High performance and environmental resistance at low price Robust in tightening Long sensing range Cost effective The tightening torque has been improved to approx. four times greater than that of conventional models because of its thick case. As the sensor can be securely tightened, it does not get loose due to vibration or shock. The GX-N series features 1.6 times longer sensing range than conventional models. Setting with enough margin is possible. It combines high reliability with cost effectiveness.
