1.Cable connecting definitions

Red Line------VCC 5VDC or 9-24VDC

Black Liine-----GND

White Line-----RX,

Green Line----TX;

Yellow Line------SGND;

Under the condition of bad measurement(for example if the ambient light is too strong. The point measured diffuse reflection coefficient is too big or too small, measurement accuracy has big error:±1 mm+40PPM)


Kindly Prompt: If need to DB9 Female head, so RX,TX and G will be corresponding to connection to Second, Third and Fifth base pin of DB9 head separately.

Frequently Asked Questions (FAQ)



On what kind of targets can be measured?

All opaque targets can be measured. Reliable measurements on transparent targets are not possible.


How is the measurement rate influenced?

The measurement rate is influenced by the target. If the laser light is well reflected by the target, fast measurement rates can be achieved (up to 0.15s in tracking mode).


Does dust influence the measuring process?

If dust overcasts the main part of the laser beam, then your
measurement will be influenced in a negative way. However, this situation can only be found in extreme dusty environment like cement hopper etc.


Is it possible to measure to a moving target?

Yes it is possible. The measured distance is the mean value between the distance at start and end of the measuring process.


What is the Measuring Accuracy?

The measuring accuracy corresponds to the ISO-recommendation ISO/R 1938-1971 with a statistical confidence level of 95% (i.e. ±twice the standard deviation, refer to diagram right. The typical measuring accuracy relates to average condition


Is the Laser Light eye safe?

Class II lasers are low power (< 1mW), visible light lasers that could possibly cause damage to a person's eyes. Some examples of Class II laser uses are: classroom demonstrations, laser pointers, aiming devices and range finding equipment. If class II Laser beams are directly viewed for long periods of time (i.e. > 15 minutes) damage to the eyes could result. Avoid looking into a Class II Laser beam or pointing a Class II laser beam into another person's eyes. Avoid viewing Class II laser beams with telescopic devices. Realize that the bright light of a Class II Laser beam into your eyes will cause a normal reaction to look away or close your eyes. This response is expected to protect you from Class II Laser damage to the eyes.


Can I connect the DLS device to a Siemens PLC?

Yes, you can connect a  device with the RS422 interface to a Siemens S7 PLC. Please find a detailed example in the application section. (AN2010)
