The Telemecanique XS618B1PAL2 is an M18 shielded inductive proximity sensor from the XS6 series. It delivers an 8 mm sensing range with a PNP normally-open output, rated for 12-48V DC supply. The extended range feature provides detection further than standard shielded M18 proxes, and the IP68/IP69K rating suits high-pressure washdown environments.
The 8 mm maximum sensing distance is the headline figure, but the minimum operating distance is 4 mm when flush-mounted in steel. Shielded construction allows flush installation without derating, though the extended range compensation means you get the full 8 mm on a standard steel target. The IP68/IP69K enclosure withstands immersion and hot-water jets, making it a fit for food-and-beverage or washdown stations. Load current maxes at 200 mA, enough for most PLC inputs or relay coils.
