Lanbao LR08-Y DC 2/4mm 2-Wire Inductive Sensor

Lanbao LR08-Y DC 2/4mm 2-Wire Inductive Sensor

Lanbao LR08-Y-DC 2-Wire Series is an M8 cylindrical inductive proximity sensor for non-contact metal detection in compact automation equipment, fixtures, conveyors, and machine-position feedback points. It provides 2mm and 4mm sensing-distance options while keeping a small threaded M8 housing.

This listing covers LR08BF02 and LR08BN04 DC 2-wire variants with normally-open or normally-closed output logic. Cable-output, E1 M8 connector, and E2 M12 connector versions are available, allowing the sensor to match fixed wiring, compact connector wiring, or standardized industrial connector layouts.

Integration Notes & Hardware Guidance

• Two-wire wiring: Use the sensor with a compatible DC 2-wire input loop and confirm that the controller input can tolerate residual voltage and leakage current.
• Logic selection: Choose normally open or normally closed based on the required signal state when a metal target is detected.
• Sensing-distance selection: Use 2mm quasi-flush variants for tighter mounting conditions, or 4mm non-flush variants when additional sensing distance is needed.
• Mounting condition: Nearby metal, target size, and installation clearance can affect the actual switching point, especially on compact M8 sensors.
• Connection choice: Select cable versions for fixed wiring, E1 M8 connector versions for compact disconnect wiring, or E2 M12 connector versions for common industrial connector layouts.

FAQ

What does the LR08-Y-DC 2-wire sensor detect?

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

What sensing distances are available?

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

Is this the same as a 3-wire NPN or PNP sensor?

No. This is a DC 2-wire sensor. Check that your controller input is compatible with 2-wire sensor residual voltage and leakage current before installation.

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.

What is the difference between cable, E1, and E2 variants?

Cable variants use a fixed 2m PVC cable, E1 variants use an M8 connector-style connection, and E2 variants use an M12 connector-style connection for easier installation or replacement.
