LZR-U920 / U921

COMPACT RAW DATA LASER SCANNER

Technology Laser

Description

BEA’s LZR^®-U920 / U921 are LASER-based measurement devices measuring distances on up to four planes. The LZR-U920 / U921 can be installed to scan in any direction.

This family of sensors is designed to provide the user with the highest degree of flexibility. It communicates the raw measurement data for further calculation or control tasks.

Features

Background independent

Background or substrate has limited effect on measurements

Laser-based measurement

Measurement range: up to 65 m (213 ft)

Uni-directional or Bi-directional

Standard RS485 bus communication (bi-directional)

Superior object recognition

No external illumination of target object necessary as compared to camera systems
