What the 10 mm sensing range means on a cold line
The SIES-8M-PO-24V-K-10-M8D: A 10 mm flush-mount inductive sensor like this one detects ferrous targets at that distance without needing a free-zone around the head. In a refrigeration skid or freezer-door interlock, that range is enough to sense a cam or flag passing through the sensing face without the sensor body protruding into the ice-up zone. The M8 connector keeps the cable changeout fast when a line-down swap is needed — no hardwired pigtail to splice.
