2km laser rangefinder with rs232 or 485 interface Wavelength 905nm measurement itme 1s working temp: -20C - 60C

NOTE: If the laser sensor has any quality problem while using. Please contact the supplier for technical support, please don’t repair or disassemble by yourself, Thanks for your cooperation!. 

Baud Rate:9600   Stop bit::1Transmission Digit::8-Bit     Odd-even check::No

For example:  If to connect DB9 Female head, it will be corresponding to Second, Third and Fifth base pin of DB9 head separately, the corresponding line is Purple line , Grey line and Black line.

Connect the power supply according to the connection instructions. Connect the sensor data interface to the PC (or CPU) serial port

For example: if the measurement result is 528m, it displays DA 05 82 EE

All data are HEX standard, which data high and low data in the form of BCD code to represent the distance data. Data unit: m, for example, distance is 582m, so Range sensor issue instructions for “0xDA  0x05  0x82  0xEE”,“0x” represents Hexadecimal data. If distance measurement failed ( for example no display distance measurement ), so issuing “0xDA  0x00  0x00  0xEE”.

Single measurement:

Ranging command: 0x0B

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.

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.
