Lanbao LR12X High-Temp M12 2/4mm Inductive Sensor Lanbao LR12X High Temperature Resistant Series is an M12 cylindrical inductive proximity sensor for non-contact metal detection in hot industrial environments, heated machinery, drying equipment, conveyors, process fixtures, and automated control systems. It keeps the compact threaded LR12X housing format while extending the operating temperature range for applications where standard sensors may be unsuitable. This listing covers LR12XBF02W and LR12XBN04W DC variants with 2mm flush or 4mm non-flush rated sensing distance. Depending on the selected part number, the sensor is available with NPN or PNP output, normally-open or normally-closed logic, and either fixed silicone cable or E2 M12 connector wiring.
