The XS208BLNAL2 is a Series XS2 inductive proximity sensor from Telemecanique Sensors, built for detecting ferrous targets in tight spaces. Its 8 mm diameter M8 threaded brass body with nickel plating handles washdown environments (IP67, NEMA 4X), and the 3 mm unshielded sensing range catches metal objects passing within that gap — useful for end-of-travel or part-presence checks on compact assembly fixtures.
Runs on 12-24V DC and switches a 200 mA load through an NPN normally-open output — that is a standard sinking signal for most PLC digital inputs. The 3-wire prewired cable (2 m, bare ends) means you terminate it in a junction box or terminal strip; no connector to swap. The M8 thread is common for proximity sensors in this class, so replacement or retrofit into an existing tapped hole is straightforward.
