General Information
The laser distance sensor LDS70A was developed for industrial applications. It
enables non-contact measurement of distances in a large working range and
with a high sampling rate up to 40 kHz to almost any diffusely reflecting
surface to 70 m and up to 320 m on reflectors. The sensor uses an eye-safe
laser radiation at a wavelength of 905 nm (infrared).
The IP67 housing of the LDS70A is impact and shock resistant and ideally
suited for use in harsh industrial environments.
The LDS70A has a selectable RS232 and RS422 interface, an analog output and
2 digital outputs.
The LDS70A is characterized by very compact and rugged design, easy
mounting, low power, adjustable switching outputs and the ability to set user-
specific parameters. This opens up a variety of uses in industrial applications.

The LDS70 sensor operates on the basis of time of flight measurement. Short
laser pulses are transmitted. The light pulse reflected from the target is
detected by the receiver. The distance can be determined by the time shift.
The measurement range depends on the reflectivity and the surface type of
the measured target.
