The Telemecanique XS1M18DA9AV is an 18 mm diameter inductive proximity sensor from the XS series — a 2-wire shielded barrel with a metal body, normally-open output, and 48 VDC operating voltage. It switches loads up to 100 mA and is rated for -13 to 158 °F. The shielded construction allows flush mounting in metal without derating, typical for detecting ferrous targets in tight machine frames or conveyor rollers.
How It Compares to XS1M18MB250K
The XS1M18MB250K has a normally-closed output, 24 to 240 VAC/VDC operating voltage, and 5 mm sensing distance. The XS1M18DA9AV is normally-open at 48 VDC.
Panel Fit & Installation
Threaded barrel, 18 mm diameter fits standard 18 mm holes. Metal body withstands weld-splash. The 2-wire NO output closes on detection; verify polarity for inductive DC loads. Operating range -13 to 158 °F.
