Cylinder position sensing — what the sub-category tells you
The XS1M30AB120SB4 is listed under the Cylinder Position Inductive Proximity Sensor sub-category, meaning it is designed to detect the position of a pneumatic or hydraulic cylinder piston — typically a ferrous target at the end of stroke — through the cylinder wall or a flag on the rod. The M30 barrel form factor is standard for this class; the sensor body threads into a mounting bracket or cylinder port, and the sensing face is flush or non-flush depending on the variant. The sub-category implies a sensing range optimised for cylinder stroke detection, not general-purpose proximity.
