Lanbao US40 | Ultrasonic Sensor | 40-500mm

Lanbao US40 – ultrasonic distance sensor

The Lanbao US40 is a ultrasonic distance sensor built for ultrasonic sensing in industrial automation equipment. Lanbao’s official specification lists 40-500mm, NPN NO/NC; NPN Hysteresis mode; 0-5V Analog output; 0-10V Analog output; PNP NO/NC; PNP Hysteresis mode; 4-20mA Analog output; Com TTL232 (based on current SKU options), 20…30VDC supply, and 4 pin M12 connector. 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 UR18-DC60, Lanbao UR12-DC40, and Lanbao PDE-CR30 so the housing style, measurement method, and control output match the machine input.

Board Layout & Label Guide

• Ultrasonic transducer face – Keep the active face clean and align it to the target path required by ultrasonic sensing.
• 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 – 4 pin M12 connector; route the cable or connector with strain relief before final commissioning.
• Supply input – Wire the sensor only within 20…30VDC; confirm polarity before applying power.
• Output selection – Match the selected SKU to this listing’s output coverage: NPN NO/NC; NPN Hysteresis mode; 0-5V Analog output; 0-10V Analog output; PNP NO/NC; PNP Hysteresis mode; 4-20mA Analog output; Com TTL232 (based on current SKU options).
• Adjustment / teach control – With teach-in function; 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.
