Extremely fast and compact distance sensor

The LDS30A laser distance sensor is intended for general distance measurements that require extremely fast data acquisition.
It provides up to 30,000 centimeter-precise measuring values per second – up to 30 m without a reflector. With appropriate reflectors the LDS30A reaches objects at distances of up to 250 m.


The sensor has been optimized for easy system integration and has a shock-proof and impact-resistant IP 67 housing. Thus, it is most suitable for applications that impose high impact on the sensor, such as harsh industrial environments.
Due to the invisible and eye safe laser (905 nm) the LDS30A can also be used in public areas.
