Mounting and wiring notes
M18 threaded body with a 2 m prewired cable terminated in bare wires. The 2-wire AC/DC circuit is polarity-sensitive on DC but self-rectifying on AC; wire color coding follows the standard brown (V+ / L) and blue (V- / N) convention for the series. The integral LED indicator confirms output state — lit when the output is conducting (target absent for NC version). The unshielded construction provides an 8 mm sensing range.
