It's designed for non-contact detection of metal targets in automated machinery — think end-of-stroke sensing on pneumatic actuators, part-present checks on conveyors, or position feedback on pick-and-place grippers. The 7.5 mm sensing distance (embedded in the order code) puts it in the short-to-medium range class for an 8 mm cylindrical sensor, which is typical for tight mounting spaces where you need reliable detection without mechanical contact.
What the 24 V supply and 7.5 mm range mean on the line
Rated for 24 V, which is the standard control voltage in industrial panels — no separate power supply needed if your PLC or I/O rack already runs 24 VDC. The 7.5 mm nominal sensing distance means it detects ferrous targets passing within that gap; for steel, that's the rated range, and for other metals you'll get a derated distance (typically about 60% for aluminum, 40% for brass). In a pneumatic cylinder application, mount it so the piston head or a flag passes at 7.5 mm or closer, accounting for mechanical tolerances and any non-ferrous target material. The cylindrical M8 form factor fits standard mounting brackets and through-hole clamps common in Festo and third-party actuator kits.
