SICK WT250-P172 Description



  • Visible red light
  • 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 12 - 240 V DC/ 24 240 V AC voltage supply in compact design
  • UL recognized
  • Your benefits

  • Visible red light simplifies alignment and easy-to-read positioning indicator for simple commissioning
  • 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
