Lanbao LR30XB-Y DC 15/22mm 3/4-Wire Inductive Sensor

Lanbao LR30XB-Y DC 15/22mm 3/4-Wire Inductive Sensor

Lanbao LR30XB-Y-DC 3/4-Wire Series is an M30 cylindrical inductive proximity sensor for non-contact metal target detection in industrial automation, machine equipment, conveyor positioning, fixtures, and control systems. It provides 15mm quasi-flush and 22mm non-flush sensing options, giving a larger detection range than smaller M12 and M18 inductive sensor families.

This listing covers LR30XBF15 and LR30XBN22 DC variants with NPN or PNP output and normally-open, normally-closed, or NO+NC logic options. Cable-output and E2 M12 connector versions are available, allowing the sensor to match fixed wiring layouts or quick-disconnect 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 NO, NC, or NO+NC variants based on the required signal state and whether your system needs complementary output signals.
• Sensing-distance selection: Use 15mm quasi-flush variants for tighter mounting conditions, or 22mm non-flush variants when longer detection distance is more important.
• Mounting condition: Nearby metal, target size, and installation clearance can affect the actual switching point, especially for non-flush high-distance variants.
• Connection choice: Select cable versions for fixed wiring or E2 M12 connector versions when quick replacement and standardized industrial connectors are preferred.

FAQ

What does the LR30XB-Y-DC sensor detect?

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

What sensing distances are available?

This series includes 15mm quasi-flush variants and 22mm non-flush variants. Select the version that matches your mounting condition and required detection margin.

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, NC, and NO+NC?

NO switches on when a metal target is detected, NC switches off when a target is detected, and NO+NC provides complementary output behavior on supported 4-wire variants.

What is the difference between cable and E2 variants?

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