The Telemecanique XS1M18PA370 is a cylindrical M18 inductive proximity sensor from the OsiSense XS1 family, flush-mountable with a PNP normally-open output and a 2 m pre-wired cable. It detects ferrous targets at 5 mm (Sn) and switches at up to 2 kHz, making it a fit for high-speed part-presence or position sensing on automated assembly and packaging lines where the sensor must survive washdown environments.
The 5 mm nominal sensing distance (Sn) is specified for flush mounting in steel — meaning the sensor face can be level with the surrounding metal without false triggering, which is essential when mounting into a machine frame or bracket. The 2 kHz switching frequency supports counting or timing applications well above the typical 50–200 Hz of general-purpose proxes; a passing part at 2 m/s needs roughly 1 mm of target dwell, and this sensor's response time (~0.25 ms) catches it cleanly.
