Compact inductive sensor for tight zones
This Telemecanique XS106B3PAL2 is a 6.5 mm barrel inductive proximity sensor with a 2.5 mm flush sensing range, PNP normally-open output, and 12–24 VDC operation. Switching frequency reaches 2500 Hz, fast enough for detecting small parts on a conveyor or confirming a divert arm position. The IP65/67 nickel-plated brass housing handles washdown areas, and the 2 m PVC cable runs straight to the control cabinet without a separate connector. It drops into the tightest zone—think 6.5 mm holes drilled into a roller-mount bracket or alongside a pneumatic cylinder. Flush mounting means it sits level with the metal it’s monitoring, so there’s no protrusion to snag product or jam the line.
Why the XS1M18MB250K isn't a drop-in
The XS1M18MB250K looks like it belongs to the same XS family, but it’s a different animal. That unit uses an 18 mm threaded barrel, runs on 24–240 VAC/VDC, switches at 25 Hz (AC) or 2000 Hz (DC), and outputs NC. The XS106B3PAL2 is 6.5 mm, 12–24 VDC only, PNP NO, and switches at 2500 Hz. The mounting hole, wiring, and logic are all incompatible—no physical swap without re-drilling and re-wiring. If a panel was specced around the 18 mm sensor, the XS106B3PAL2 won’t fit the bore or the voltage supply. Keep the 6.5 mm part for new builds or retrofits where space is the constraint, not a line-down replacement for the larger unit.
