DC 2-wire Cylindrical Inductive Proximity Sensor Amplifier Built-in 2-wire type Oil resistant Metal embedding possible available GXL INDUCTIVE PROXIMITY SENSORS GX-U/FU SERIES GX-U/FU GL-18H/18HL GL-N12 Amplifier Built-in GL-8/8U GL-6 High performance & ease of use Conforming to EMC Directive Robust in tightening Compact size: "5.4 mm "0.213 in Long sensing range 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. GX-5SU(B) is just 5.4 mm 0.213in in diameter, the smallest in existing DC two-wire sensors. It saves you space. The GX-U series features 1.6 times longer sensing range than conventional models. As it can be mounted at a sufficient distance from the object, there is no fear of the sensor and the object colliding. Conventional GX-18M(B) model 19.6 N•m or less 4 times approx. GX-18MU(B) GX-12MLU(B) "5.4 mm "0.213 in 8 mm 0.315 in 80 N•m or less s 1.6 GA-10/GH Amplifier-separated GX GX-N GX-12ML(B) time Conventional model 5 mm 0.197 in 2-color indicator Simple wiring Spatter-resistant type available The normally open type is equipped with a 2-color indicator. The normally closed type has the operation indicator instead. The operation is easily observable from any direction because the entire sensor tail lights up. The wiring cost is considerably reduced as it is DC 2-wire type. Further, each of GX-12MU(B), GX-18MU(B), GX-30MU(B) is available as a pigtailed model (300 mm 11.811 in long cable with attached connector) that makes replacement easy and quick. 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. ( ) 722 APPLICATIONS Controlling depth of drilling Positioning object at welding station (GX-FU-J only) By detecting the dog, the sensor decides the depth of the drilled hole. It can reliably detect even aluminum pallets because of its long sensing range. It can be safely used even where welding sparks (spatter) fly around.

Stainless steel (SUS304) Brass Aluminum Wiring • The sensor must be connected to a power supply via a load. If the sensor is connected to a power supply without a load, the short-circuit protection makes the sensor inoperable. (The output stays in the OFF state and the indicator does not light up.) In this case, rectify by connecting the power supply via a load. Now, the sensor becomes operable. Further, take care that if the power supply is connected with reverse polarity without a load, the sensor will get damaged. GX-5SU(B) 1 0.63 approx. 0.32 approx. 0.30 approx.
