Industrial sensing fit
The Turck BI8U-EM18WD-AN6X is an M18 inductive proximity sensor built for machine builders and maintenance engineers who need reliable metal detection in wash-down zones. Its NPN normally-open output suits standard 10…30 VDC control circuits and the stainless-steel barrel withstands mechanical abuse.
Factor 1 detection
A single specification decides suitability: the sensor delivers Factor 1 for all metals, so sensing distance does not change between steel, aluminium, brass or copper. If the application requires different switch points for different metals, this unit will not meet that need.
Sustained harsh duty
Continuous exposure to high-pressure cleaning at IP69K, temperatures from -40 °C to +100 °C and aggressive acid or alkaline agents is handled by the double-lip seal and liquid crystal polymer front cap. Magnetic-field immunity prevents false triggers near welding equipment or large motors during extended shifts.

Questions about this item
What does the 8 mm sensing range mean when the sensor is mounted in a machine?
The 8 mm range is the maximum distance at which the sensor reliably detects any metal target; in practice you mount the M18 barrel so the target passes within that 8 mm window for a stable NPN switching signal.
How does the DC 3-wire 10…30 VDC interface limit the way I wire the NPN output?
The sensor needs a 10 to 30 VDC supply and switches the load to ground through its NPN transistor; the cable connection provides the three conductors for supply, ground and switched output.
What clearance and thread size are required to fit the M18 x 1 stainless barrel?
The sensor uses an M18 x 1 thread and a stainless steel 1.4404 barrel, so you need an 18 mm threaded hole or nut and enough space for the barrel length and cable exit.
