SERIES DC -wire Cylindrical Inductive Proximity High Performance & Ease of Use Marked Conforming to EMC Directive Robust in Tightening 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. Conventional GX-8M(B) model GX-8MU(B) 9.6N m or less times approx. 8N m or less Compact Size: ".mm GX-SU(B) is just.mm in diameter, the smallest in existing DC two-wire sensors. It saves you space. ".mm ong Sensing Range The GX-U series features.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. GX-MU(B) 8 mm.6 times GX-M(B) Conventional model mm -color Indicator The normally open type is equipped with a -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. Simple Wiring The wiring cost is considerably reduced as it is DC -wire type. Further, each of GX-MU(B), GX-8MU(B), GX-MU(B) is available as a pigtailed model (mm long cable with attached connector) that makes replacement easy and quick. Spatter-resistant Type Available 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. 66 ECFA S.R.. Av.

Others Do not use during the initial transient time (ms) after the power supply is switched on. When the sensor is mounted on a moving base, stress should not be applied to the sensor cable joint. Refer to P.86l for general precautions. 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. Blue lead wire Brown lead wire DC power supply For series connection (AND circuit) or parallel connection (OR circuit) of sensors, take care of the following. Series connection (AND circuit) When all sensors are in the ON state, the load voltage VR is given by: VRVCCn(V) Vcc: supply voltage (V DC max.) n: number of sensors Make sure that the load can work properly at this voltage.
