DX-7 SERIES PHASE DIFFERENTIAL DETECTOR


 

This product is a phase differential detection type distance sensor that has two outputs, an analog output (current output of 4-20mA) and a comparator output (normal or 1 point zone).

This distance sensor is designed to adopt a new technology to measure a distance by detecting the phase differential of light (differential of time).

Neither the influences of change in the receiving light quantities nor the influences of the background object are easily received. Therefore stable long distance detection can be obtained.
