cylindrical sizes. These reliable DC-powered (10-30V or 15-30V) threaded-barrel sensors are IP67 rated and are available with 2m pigtail cable or quick-disconnect. 8mm analog inductive proximity sensors detect the presence of ferrous metal objects at distances from 0 to 4mm and provide a variable output (0-5 VDC or 0-10 VDC). 12mm, 18mm and 30mm analog inductive proximity sensors detect the distance of ferrous metal objects from 0-6mm, 0-10mm and 0-20mm respectively, providing a variable mA or voltage output (0-5 VDC / 1-5 mA and 0-10 VDC / 4-20 mA) linear to distance signal. Rectangular 8mm x 8mm analog output sensors are also available with 0 to 4mm sensing range. With a lifetime warranty, these UL approved analog proximity sensors start at $92.00.
