US40-CC50DI-E2, LANBAO, ultrasonic sensor, Sn 40–500 mm, connector M12/4 pins

US40-CC50DI-E2 – Ultrasonic distance sensor

US40-CC50DI-E2 is an ultrasonic distance sensor from LANBAO. It measures the time of flight of an ultrasonic pulse reflected from the object, so it works regardless of the colour, gloss and transparency of the material.

Key features

• Sensing distance 40–500 mm.
• Supply 20–30 V DC.
• Connection: connector M12.
• Degree of protection IP67 – protection against dust and temporary immersion.

Technical specifications US40-CC50DI-E2

Wiring of US40-CC50DI-E2 by wire colours

Setting the sensing distance (Teach-in): set point A2 by connecting the white wire to the brown (plus), point A1 by connecting the white wire to the blue (minus). Place the object at the required distance, connect the wires for two to three seconds until the blue indicator starts flashing, then disconnect the white wire. Teaching is active only for the first five minutes after switching on; after that the sensor must be switched on again.

Do not set points A1 and A2 closer than 20 mm from the blind zone, otherwise measurement accuracy and stability suffer. After switching on, the sensor warms up – it reaches full accuracy after about half an hour of operation.

The colour coding complies with IEC 60947-5-2. Always compare the actual pin and wire assignment with the diagram in the sensor datasheet (Downloads tab).

Pin assignment according to the manufacturer's catalogue. Pin 2 (white) is the Teach-in wire, not an output.

Connection cable for US40-CC50DI-E2

The sensor has a connector M12, 4 pins, male (external thread with pins), so it requires a cable with a femaleconnector. The cable is not included.

• QE12-N4G5-N – M12, 4 pins, female, angled 90°, 5 m, PVC, with LED indication
• QE12-N3G5-P – M12, 3 pins, female, angled 90°, 5 m, PVC, with LED indication PNP
• QE12-N3G5-N – M12, 3 pins, female, angled 90°, 5 m, PVC, with LED indication NPN

The sensor has one output, so a three-pin cable is sufficient. A four-pin cable can also be used – the fourth wire remains unconnected.

PUR version: we do not yet stock a M12 female cable with a PUR jacket (for oils, coolant emulsions, abrasion, low temperatures and drag-chain installation). Contact us and we will source it. A cable with a PVC jacket is intended for normal dry machine environments.

The LED indication of the switched output in the connector is designed for the PNP NO version. With other output combinations the cable works electrically, but the indicator may not show switching – in that case choose a cable without indication.

Typical applications

• level measurement and monitoring of liquids and bulk solids
• detection of transparent objects to which optics do not respond
• distance measurement and position monitoring in dusty environments
• checking stack height or silo filling
• detection of shiny and dark surfaces

How to choose and what to watch out for

• Connector connection M12: a separate connection cable with a matching connector is required for operation – you will find it in the Cables with connector category.
• Degree of protection IP67: protection against dust and temporary immersion. Not designed for permanent immersion or high-pressure washing – this requires IP69K.

Frequently asked questions

What is the sensing distance of US40-CC50DI-E2?

The sensing distance (Sn) is 40–500 mm.

How is US40-CC50DI-E2 connected?

US40-CC50DI-E2 is supplied with the connection: connector M12. A connection cable with a matching connector must be ordered separately.

How is the sensing distance set on US40-CC50DI-E2?

Using the Teach-in function via the white wire. Connecting the white wire to the brown sets point A2,; connecting it to the blue sets point A1. Teaching is active only for the first five minutes after switching the sensor on.

Which cable do I need for US40-CC50DI-E2?

Cable with a female M12 connector. We stock QE12-N4G5-N (4 pins, 5 m, PVC); for sensors with one output, three-pin QE12-N3G5-P or QE12-N3G5-N. can also be used. The cable is not included.

Does ultrasound detect transparent and shiny objects?

Yes. Ultrasound works with sound, not light, so transparency, colour or gloss do not matter. On the other hand, very soft and porous materials that absorb sound cause problems.
