An HTM Sensors long range inductive proximity sensor in a shielded 12 mm threaded barrel, with a chrome plated brass housing, a PNP normally open output and a four pin M12 quick connect. The extra sensing distance is the point: it lets you mount the sensor further back from a target that keeps finding the face.
Long range versions of a standard barrel size exist for one practical reason. On a machine that vibrates, or where a fixture has been shimmed a few times over ten years, a sensor set at a short gap eventually gets hit. Backing the sensor off and buying the range back is cheaper than rebuilding the mount. The trade-off is that the same body now reads targets further away than the original sensor did, so check anything metallic sitting behind or beside the target before you swap one in.

Pro tip from the counter
The 200 mA is the output's limit, not the sensor's appetite — the barrel itself draws under 10 mA. Sensors on this family almost never die of old age; they die because somebody hung a solenoid or a small contactor straight off the black wire. Put a relay in between and the sensor outlives the machine.
Best for: maintenance and controls techs replacing a short-range M12 prox that keeps getting struck, and machine builders who need standoff without stepping up to an 18 mm barrel.
Is the 6 mm sensing range the same on aluminium or stainless?
The datasheet publishes a single sensing range figure and does not list correction factors for other target metals on this sheet. Confirm the target material with HTM before you design a machine around the full published distance.
Can the output drive a contactor coil directly?
Check the coil first. The datasheet caps the output at 200 mA and puts the overload trip point just above that, so anything with a meaningful inrush needs an interposing relay rather than a direct connection.
Does a cable come with the sensor?
No. This version terminates in a four pin M12 quick connect, so you buy the cordset separately. The datasheet gives the pinout as brown, blue and black with pin two unused.
Will it survive inside a welding cell?
The datasheet answers this plainly: weld field immune is listed as No and weld spatter resistant is listed as No. For welding duty HTM builds a different family and you should specify that instead.
