Turck BI8-M18E-LIU-H114 inductive sensor M18×1 15…30 VDC M12×1

M18×1 inductive sensor for analog position feedback

The Turck BI8-M18E-LIU-H114 is a flush-mount inductive sensor with a threaded M18×1 barrel. It operates on 15…30 VDC and delivers simultaneous 0…10 V and 0…20 mA analog outputs. The M12×1 male connector provides a standard four-wire electrical connection. This sensor suits engineers who need continuous position data from metal targets in industrial machinery.

Sustained-load behaviour of the analog output stage

Under continuous operation the sensor maintains its analog output without switching transients that affect discrete-output models. The chrome-plated brass housing (CuZn) dissipates heat from the output driver during extended 0…20 mA current-loop use. Voltage output remains stable across the 15…30 VDC supply range during long duty cycles. Installations requiring only digital on/off detection will not use the analog capability.

Build quality and connector implications day to day

The metal housing with chrome-plated finish resists coolant, oil and mechanical wear in harsh environments. Flush mounting allows the M18×1 barrel to sit level with surrounding metal without reducing the sensing field. The M12×1 connector enables quick replacement without rewiring the cable loom. At 62 g the unit adds minimal mass to moving fixtures. Applications needing non-flush mounting or plastic housings must select a different model.
