Autonics PRL18-5AO is a cylindrical inductive proximity sensor (M18) with flush-mount capability, featuring a 5 mm sensing distance and a Ø18 mm sensing face designed to detect iron targets (standard 18×18×1 mm iron) at close range. It is powered from 90–250 VAC (50/60 Hz) with an operating range of 85–264 VAC, and uses a two-wire normally open output in a shielded, long-body package for reliable operation in industrial environments; a red LED indicator provides status at a glance. The long-body version runs about 80 mm long and weighs roughly 130 g (≈142 g packed), with a 20 Hz response frequency suitable for moderate-speed automation tasks.
