Lanbao LE18 5/8mm DC Rectangular Inductive Sensor

Lanbao LE18 5/8mm DC Rectangular Inductive Sensor

Lanbao LE18-DC 3-Wire Series is a rectangular inductive proximity sensor for non-contact metal detection in automation equipment, machine fixtures, conveyors, and position feedback systems. The compact block-style body provides a flat mounting format when a cylindrical threaded sensor is not ideal.

This listing covers LE18SF05 and LE18SN08 variants with flush 5mm or non-flush 8mm sensing distance. NPN and PNP outputs are available with normally-open or normally-closed logic, helping the sensor match different PLC, controller, and I/O module input requirements.

For related Lanbao sensors, compare the Lanbao LE17 Rectangular Inductive Sensor, Lanbao LE10 Rectangular Inductive Sensor, and Lanbao LE40SZ Square Inductive Sensor. For round cylindrical options, see the Lanbao LR18X-DC 3/4-Wire Inductive Sensor.

Integration Notes & Hardware Guidance

• Output selection: Choose NPN or PNP according to the input type of your PLC, controller, counter, or I/O module.
• Logic selection: Choose normally open or normally closed based on the required signal state when a metal target is detected.
• Sensing-distance selection: Choose 5mm flush variants for shielded installation or 8mm non-flush variants when additional sensing distance is needed.
• Mounting condition: Keep the metal target within the assured operating range and leave suitable clearance around non-flush versions to avoid false switching.
• Wiring check: Confirm supply voltage, output polarity, and cable wiring before applying power to the sensor.

FAQ

What does the Lanbao LE18 sensor detect?

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

What sensing distances are available?

This listing includes 5mm flush variants and 8mm non-flush variants. Select the version that matches your mounting condition and detection distance.

How do I choose NPN or PNP?

Match the output type to your controller input. Choose NPN or PNP according to the wiring standard used by your PLC, controller, or I/O module.

What is the difference between NO and NC?

NO means the output switches on when a metal target is detected. NC means the output switches off when a metal target is detected.

How is LE18 different from a round LR sensor?

LE18 uses a rectangular block housing, which can be easier to mount on flat brackets or compact equipment where a round threaded sensor is less convenient.
