Lanbao LR04Q-DC 3-Wire Series is a compact cylindrical inductive proximity sensor for non-contact metal detection in tight installation spaces. The M4 stainless-steel housing, 0.8mm flush sensing distance, and DC 3-wire output options make it suitable for precise position feedback where a miniature sensor body is required.

This listing covers LR04QAF08 series variants with NPN or PNP output and normally-open or normally-closed logic options. Cable-output and E1 connector versions are available, allowing the sensor to match different wiring and maintenance requirements.

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 the metal target is detected.
Mounting distance: Keep the metal target within the rated operating range and avoid mechanical contact with the sensor face.
Flush installation: This series is intended for flush mounting. Follow the recommended metal-free spacing if nearby metal affects switching stability.
Wiring check: Confirm supply voltage, output polarity, and connector or cable pinout before powering the sensor.

FAQ

What does this sensor detect?

It is an inductive proximity sensor, so it is designed for non-contact detection of metal targets.

What is the sensing distance?

The LR04QAF08 series has a rated 0.8mm sensing distance, with an operating distance reference of 0-0.64mm.

How do I choose NPN or PNP?

Match the sensor output to your controller input. Use NPN for sinking-style inputs and PNP for sourcing-style inputs, depending on your wiring standard.

What is the difference between NO and NC?

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

What is the difference between the standard and E1 variants?

The standard variants are cable-output versions, while the E1 variants use a connector-style connection for easier replacement and maintenance.
