> 1025912
At a glance
• Sender LED with visible red light
• Autocollimation optics with polarizing filter
• Sensitivity control via potentiometer
• Immune to ambient light
• Optional test input for system diagnostics
• Rugged plastic housing
Your benefits
• Fast installation due to highly visible red light saves time
• Reliable detection of shiny objects without a blind zone due to autocollimation
optics and a polarizing filter
• Quick and easy sensing range adjustment due to 270° potentiometer
• Crosstalk and ambient light immunity reduce false readings and downtime
• Reliable availability in the field
