Sick DT20-N244B Overview
DT20-N244B DT20 Hi: Distance sensor with display Measuring range 100...300 mm, analog output 4...20 mA, NPN switching output Q/Q cross- wise; outputs individually scalable via teach-in/manual adjustment
Sick DT20-N244B Description
- Four measuring ranges from 50 mm through 1,000 mm
- Very high accuracy of up to 0.5 mm
- CMOS receiving element enables accurate distance measurement independent of color or shininess
- Red laser
- Freely scalable analog and switching output
- Display with easy to use setup menu
- Advanced settings (e.g., averaging, external laser-off, etc.)
- Reliable, precise measurement, independent of surface, increases production quality
- Reliable and consistent measurements, regardless of color, reduce changeover time
- Advanced settings provide increased application flexibility to easily solve customer-specific applications
- Fast commissioning via button, remote or numerical teach
- Easy, precise alignment and verification based on red laser light and LC display, decreasing commissioning time
- Tough metal housing permits operation in harsh environments
