If an autotransformer is utilized, the main body or power supply may be damaged. • If the used power supply generates a surge, connect a surge absorber to the power supply to absorb the surge. • In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground. • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. • Damage or burnout may result in case of short circuit of load or miswiring. • Make a cable length as short as possible to lessen noise pickup. Others • Our products have been developed / produced for industrial use only. • Avoid using a product where there is excessive vapor, dust or corrosive gas, or in a place where it could be exposed directly to water or chemicals. • Take care that the sensor does not come in direct contact with water, oil, grease or organic solvents, such as, thinner, etc. • Do not use in an environment containing infammable or explosive gases. • Never disassemble or modify the product. 12 Cylindrical Inductive Proximity Sensor GX-M SERIES DIMENSIONS (Unit: mm in) DC 3-wire type LED Sensors 2 m cable length type (mm in) Shielded type b a LED a a b M8 GX-M8□ 33 1.30 25 0.98 45 1.77 24 0.94 GX-M12□ 35 1.38 25 0.98 50 1.97 30 1.18 M18 GX-M18□ 39 1.54 28 1.10 50 1.97 28 1.10 M30 GX-M30□ 43 1.69 32 1.26 55 2.17 32 1.26 2 m cable length type (mm in) Non-shielded type c M12 plug-in connector type (mm in) b M12 Sensors b a a b M12 GX-MK12□ 55 2.17 42 1.65 M18 GX-MK18□ 60 2.36 M30 GX-MK30□ 63 2.48 M12 plug-in connector type (mm in) c a b 66 2.60 42 1.65 44 1.73 8 0.32 72 2.83 44 1.73 8 0.32 41 1.61 13 0.51 74 2.91 41 1.61 13 0.51 DC 2-wire type LED Sensors 2 m cable length type (mm in) Standard type, Long range type b a 13 M8 a c 5 0.20 b GX-M(L)8□-U (-J) 33 1.30 25 0.98 M12 plug-in connector type (mm in) (M8 size: M12 pigtailed type) a – b 24 0.94 M12 GX-M(L)12□-U (-Z) 35 1.38 25 0.98 50 1.97 30 1.18 M18 GX-M(L)18□-U (-Z) 39 1.54 28 1.10 50 1.97 28 1.10 M30 GX-M(L)30□-U (-Z) 43 1.69 32 1.26 55 2.17 32 1.26 5 0.20 Disclaimer The applications described in the catalog are all intended for examples only.
