Laser distance sensor measures long distances

A Powelectrics product story
Edited by the Engineeringtalk editorial team Apr 26, 2006

Long-range laser distance sensor for measuring long distances in robot manufacturing cells, electronic suspension tracks and for controlling rolling processes in the paper, foil and metal industries.

As an addition to its range of laser triangulation sensors, Powelectrics has launched a long-range laser distance sensor.

The LDS 400 operates on the time of flight principal and can be used for measuring long distances in applications such as robot manufacturing cells, electronic suspension tracks and for controlling rolling processes in the paper, foil and metal industries.

This technology is based on the measurement of elapsed time between the sending and receiving of laser impulses.

It measures how long it takes for short pulses of laser light to travel to the target and back.

By using this technique, surface reflection and colour have virtually no influence.

The unit can precisely measure distances from 300 to 4000mm.

Programming of the sensor can either be carried out by using three pushbuttons on the unit, or from a PC via the serial interface.

The unit has a built-in digital display to show distance.

The analogue 4-20mA output can be scaled to operate over any part of the range and, in addition, two digital outputs can be programmed.

These can be either PNP or NPN.

A high quality aluminium housing and glass optics finish off a robust and industrial unit.

The sensor can function in a temperature range of -10 to +50C.
