At a glance
• Visible red Bright Light LED
• Background suppression
• Potentiometer with an easy-to-read positioning indicator for adjusting the sensing
range
• Cable or rotatable M12 connector
• Operating mode (light/dark) selectable via control wire
• Versions for 10 - 30 V DC or 24 - 240 V DC/ 24 – 240 V AC voltage supply in
compact design
Your benefits
• Visible red light Bright Light LED simplifies alignment and easy-to-read positioning
indicator for simple commissioning
Illustration may differ
• Reliable object detection in difficult ambient light conditions
• Cable or rotatable M12 connector provide installation flexibility
• Operating mode (light/dark) is selectable via a control cable to reduce the number
of device variants
• Variants with DC voltage and universal AC/DC voltage in the same housing
provide increased flexibility
