WORLD-BEAM QS30 Background Suppression Series
Uses & Applications
Overview
- For reliably detecting objects in a defined sensing field while ignoring objects beyond cutoff point
- 30 mm threaded barrel or right-angle mounting options
- Range of supply voltages:
- Adjustable-field models with 10 to 30V dc and bipolar NPN/PNP outputs
- Fixed-field models with either 10 to 30V dc and bipolar NPN/PNP outputs or 12 to 250V ac/24 to 250V dc and SPDT electromechanical relay output
- Push-button SET adjustable-field models with cutoff point from 50 to 300 mm
- Preprogrammed fixed-field models with 200, 400 or 600 mm cutoff
- Powerful highly collimated visible red sensing beam
- Bright LED operating status indicators visible from 360°
