IFM NS5002 Inductive NAMUR Sensor

Product overview

The ifm NS5002 (IS-2002-N/OLED/1D/1G) is an inductive NAMUR sensor in a housing measuring 28 x 10 x 16 mm, for flush mounting. It is intended for hazardous areas and has a sensing range of 2 mm (real sensing range 2 mm ± 10%), normally closed, switching up to 800 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 IIB T6 Ga Ta -20…70°C; approvals PTB 01 ATEX 2191, BVS 04 ATEX E 153 X, IECEx BVS 06.0003X. ifm gives an internal capacitance of 80 nF and an internal inductance of 110 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 PBT housing and connects through a 2 m PVC cable with 2 x 0.14 mm² conductors, and is rated IP67 for -20…70 °C ambient.
