At a glance
Selectable response time up to 16 µs• Sensing range up to 20 m, sensing distance up to 1400 mm• Bus-compatible with anti-interference• 2 x 4-digit display• Adjustable hysteresis• Rotatable display screen• High-resolution signal processing• Programmable time delays•
Your benefits
Reliable, rapid process detection, even under the most difficult ambient
conditions, such as dust, spray or mist
•
Easy commissioning and product changeover due to external teach-in• Cross-talk is eliminated when utilizing bus configuration option• Quick, easy setup and adjustment due to an intuitive operating menu• Flexible parameter adjustment due to high-resolution signal processing.
Hysteresis and time delays can be adapted to suit the application, e.g., when
detecting tiny or transparent objects
•
Easy-to-read display, even under difficult installation conditions•
