The HTM MetalHead range of 8mm diameter inductive proximity sensors offers an extended range of 2mm. The 12mm-diameter versions offer a 4mm sensing range. The sensor body is completely machined from stainless steel, including the thick sensing face, making the units well suited for rugged applications. To ensure that material, including weld splatter, does not adhere to the sensor, the stainless steel body and mounting hardware have been coated with PTFE material. These sensors operate from 10 to 30Vdc and can be supplied in NPN, PNP or DC 2-wire models. The high intensity LED output indicator light can easily be seen from a distance.
