UR30-CM4DT-E2 – Ultrasonic distance sensor

UR30-CM4DT-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 200–4000 mm.
• Supply 9–30 V DC.
• Connection connector M12, 4 pins.
• Communication interface TTL232.
• Degree of protection IP67 – protection against dust and temporary immersion.

Technical specifications UR30-CM4DT-E2

Wiring UR30-CM4DT-E2 – TTL232

Wiring and communication version correspond to the LANBAO catalogue sheet UR30-CM4, ver. 1.1 Y0807. LANBAO manufacturer documentation.

Connection cable for UR30-CM4DT-E2

The sensor has a M12 connector with 4 pins. For supply and TTL232 communication, the connecting cable must carry all four contacts: 1, 2, 3 and 4. A three-wire cable cannot carry the supply and both TX and RX lines at the same time. Choose the connecting cable and any converter according to the electrical parameters of the TTL232. interface.

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 UR30-CM4DT-E2?

The sensing distance (Sn) is 200–4000 mm.

How is UR30-CM4DT-E2 connected?

UR30-CM4DT-E2 is supplied with the connection: connector M12, 4 pins. A connecting cable with a matching connector must be ordered separately.

What communication interface does UR30-CM4DT-E2 have?

The DT-E2 version uses TTL232. The white wire (pin 2) is TX and the black wire (pin 4) is RX according to the manufacturer's diagram.

Which cable do I need for UR30-CM4DT-E2?

M12 female connecting cable with all four contacts wired. Two wires are used for supply and two for TTL232 communication (TX/RX).

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.
