BI8-M18-LIU is a Turck inductive sensor in an M18 threaded housing with analog output, for flush mounting. Its output signal is proportional to the distance of a metal target and linear across the whole measuring range. The sensor is intended for simple control tasks where the distance matters, not just presence.
- Accuracy: linearity deviation 5 %, repeatability ≤ 1 % of measuring range (0.5 % after 0.5 h warm-up), reproducibility ≤ 40 µm (≤ 20 µm after warm-up), temperature drift ≤ ±0.06 %/K
- Measuring range: 1...5 mm (St37 steel target)
- Outputs: voltage 0...10 V (load ≥ 4.7 kΩ) and current 0...20 mA (load ≤ 0.4 kΩ); measuring frequency 200 Hz
- Supply: 15...30 VDC, 4-wire, no-load current 8 mA
- Protection: short circuit and reverse polarity; no wire-break protection
- Housing: M18 x 1 thread, thread length 55 mm, chrome-plated brass, PA12-GF30 sensing face, nut torque up to 25 Nm
- Environment: IP67, ambient temperature -25...+70 °C
- Connection: 2 m PVC cable (LifYY), 4 x 0.34 mm², Ø 5.2 mm
Correction factors for other target metals (St37 steel = 1): aluminium 0.3, brass 0.4, stainless steel 0.7.
MTTF 751 years acc. to SN 29500 (40 °C).
