Its 1.5 mm sensing range means it triggers when a metal object enters that gap — tight enough for position detection on small mechanisms like cam followers or actuator end stops, but not for large-gap presence sensing. The PNP normally open output pulls high when a target is sensed, which is the standard signal for most PLC digital inputs. Rated switching current is 0.2 A, so it drives the input card directly without an interposing relay.
The metal barrel housing and IP67 rating mean this sensor handles washdown and coolant splash — common on machining centers, packaging lines, and conveyor transfer stations. It runs on 48 VDC supply, which is less common than 24 VDC in modern panels; verify your control voltage before wiring. The 2 m cable with three wires (brown, blue, black) is a direct connection to the PLC or terminal block — no quick-disconnect, so factor in cable routing and strain relief at the gland plate.
