These CJF inductive proximity sensors combine flat PBT cases, mounting openings and a red operation indicator. Select the 5mm, 6mm or 7mm sensing range, then match the setting distance and output circuit to the installation. The listed models use 10-30VDC and IP67 construction. Check the sensing target, surrounding metal and sensor spacing when arranging contactless position detection.
