Part number XS118B3PAL2 is a flush-mount tubular inductive proximity sensor from the OsiSense XS series, with an 18 mm nickel-plated brass barrel and a front sensing face of PPS. The 8 mm sensing distance and 1000 Hz switching frequency suit it for high-speed detection of ferrous targets on automated assembly or packaging lines. Output is a single PNP normally-open 3-wire DC circuit, rated 200 mA at 12 to 24 VDC.
Fit note
The flush-mount body allows the sensor to sit flush with the mounting surface, eliminating target-capture voids in tight machine frames. Because it is a PNP NO output, it will not directly replace a sensor with NC or NPN logic without rewiring the load side. The IP65/67 enclosure and nickel-plated brass body hold up to washdown and cutting fluid splatter — common in automotive transfer lines or food primary-pack equipment.
Cross-reference check
A buyer holding a panel spec'd around XS1M18MB250K cannot drop this XS118B3PAL2 in and run. The XS1M18MB250K is a normally-closed 2-wire sensor rated 24–240 VAC/VDC, while this unit is a normally-open 3-wire DC-only PNP. The barrel diameter matches at 18 mm, but the output logic and voltage range differ entirely — rewiring and a DC supply are required.
