Lanbao LE40XZ-E2 Low-Temp 15/20mm M12 Inductive Sensor Lanbao LE40XZ-E2 Low Temperature Resistant Series is a square inductive proximity sensor with an M12 connector for non-contact metal detection in cold industrial environments, refrigeration equipment, outdoor machinery, conveyors, and automated control systems. The extended LE40XZ housing provides a practical rectangular installation format while supporting low-temperature operation and detachable connector wiring. This listing covers LE40XZSF15W1-E2 and LE40XZSN20W1-E2 DC variants with 15mm flush or 20mm non-flush rated sensing distance. Depending on the selected part number, the sensor is available with NPN or PNP output and normally-open, normally-closed, or NO+NC logic.
