Lanbao PDB-CR30 | Digital Laser Sensor | +/-5mm

Lanbao PDB-CR30 – laser distance sensor

The Lanbao PDB-CR30 is a laser distance sensor built for laser distance measurement in industrial automation equipment. Lanbao’s official specification lists 5mm, RS-485; 4…20mA (based on current SKU options), RS-485:10…30VDC;4…20mA:12…24VDC supply, and RS-485:2m 5pins PVC cable;4…20mA:2m 4pins PVC cable. This OpenELAB listing summarizes the product family for selectable SKUs, so always match the required output and connection against the variant name before ordering.

For selection, confirm the sensing principle, range, output type, connection style, response time, protection rating, and accessory set against the exact SKU. Use the SKU code on the order page as the final reference for output polarity and cable style. If you are comparing nearby Lanbao models, also review Lanbao PDB-CR50, Lanbao PDB-CR85, and Lanbao PDB-CM so the housing style, measurement method, and control output match the machine input.

Board Layout & Label Guide

• Laser emission and receiving window – Keep the active face clean and align it to the target path required by laser distance measurement.
• Output indicator – Use the LED indication to confirm power, switching state, and any short-circuit or overload warning described by the official specification.
• Connection area – RS-485:2m 5pins PVC cable;4…20mA:2m 4pins PVC cable; route the cable or connector with strain relief before final commissioning.
• Supply input – Wire the sensor only within RS-485:10…30VDC;4…20mA:12…24VDC; confirm polarity before applying power.
• Output selection – Match the selected SKU to this listing’s output coverage: RS-485; 4…20mA (based on current SKU options).
• Adjustment / teach control – Use the controls described for the selected SKU; set the distance or threshold after the sensor is mounted in its final position.
• Mounting body – Use the listed accessory hardware and avoid mechanical stress on the lens, slot, or transducer surface.
• Protection rating – IP67; maintain sealing around the cable entry or connector during installation.
