IFM NG501A IGB2008BN/US/1G/1D Inductive NAMUR sensor

Product overview

The ifm NG501A (IGB2008BN/US/1G/1D) is an inductive NAMUR sensor in an M18 x 1 threaded housing 46 mm long, for flush mounting. It is intended for hazardous areas and has a sensing range of 8 mm (real sensing range 8 mm ± 10%), normally closed, switching up to 400 Hz. It connects to certified intrinsically safe circuits with maximum values of U = 15 V, I = 50 mA and P = 120 mW; the nominal voltage is 8.2 V DC (1 kΩ), and outside the hazardous area it can run on 7.5…30 V DC with up to 30 mA. ATEX marking: II 1G Ex ia IIC T6 Ga; approvals BVS 04 ATEX E 091 X, IECEx BVS 06.0003X. ifm gives an internal capacitance of 200 nF and an internal inductance of 190 µH. Correction factors are 1 for steel, 0.7 for stainless steel, 0.5 for brass, 0.4 for aluminum and 0.3 for copper. The sensor has a specially coated brass housing with a PBT sensing face and connects through an M12 connector (A-coded, 4 contacts), and is rated IP66 and IP67 for -20…70 °C ambient. Supplied with two lock nuts.
