Lanbao LR12X High-Temp M12 2/4mm Inductive Sensor

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.

Integration Notes & Hardware Guidance

• Temperature range: Use this high-temperature version when the installation requires operation above the standard LR12X temperature range.
• Sensing-distance selection: Choose 2mm flush variants for shielded installation or 4mm non-flush variants when additional sensing distance is needed.
• Output selection: Match NPN or PNP wiring to the input type of your PLC, controller, counter, or I/O module before ordering.
• Logic selection: Choose normally open or normally closed based on the required signal state when a metal target is detected.
• Connection choice: Select silicone-cable variants for fixed wiring or E2 M12 connector variants when quick replacement and standardized connectors are preferred.

FAQ

What does the LR12X high-temperature sensor detect?

It detects metal targets using inductive proximity sensing, without physical contact with the target.

What operating temperature range does this version support?

This high-temperature resistant version is listed with an operating temperature reference of -25C to 120C.

What sensing distances are available?

This listing includes 2mm flush variants and 4mm non-flush variants. Select the version that matches your mounting condition and detection distance.

How do I choose between NPN and PNP?

Choose the output type required by your controller input. NPN and PNP wiring are not interchangeable unless the receiving device supports both input standards.

What is the difference between cable and E2 variants?

Cable variants use a fixed 2m silicone cable, while E2 variants use an M12 connector-style connection for easier replacement and standardized wiring.
