It also recognises direction of travel, so entrances are managed precisely and safely, and it installs much faster than other sensors. It is programmed with the buttons or the TPRAP IR remote. - Model: PRAP - Technology: Microwave, Doppler effect - Capacity: 8 m - Power supply: 12–24 V ac/dc - Contact: 1 NO/NC - Programming: Buttons or TPRAP remote - Recognises: Direction of travel and object size - Use: Industrial and residential Operation ## Easy programming, insulation, functionality. PRAP doesn't just see that something is moving: it assesses its size and direction. - **Pedestrian, car or truck** Classifies objects by size. - **Direction of travel** Opens only for those entering, or only for those leaving. - **Quick installation** No loop to lay in the asphalt. ![PRAP microwave sensor with its cable](https://www.stagnoliaccessories.com/theme_stagnoli_accessories/static/src/img/prap.webp) Models and accessories ## Sensor and remote. ![PRAP sensor](https://www.stagnoliaccessories.com/theme_stagnoli_accessories/static/src/img/prap.webp) PRAP PRAP Doppler-effect sensor for industrial and residential use, 12–24 V ac/dc, 8 m, 1 NO/NC contact. 8 m 1 NO/NC ![TPRAP IR programming remote](https://www.stagnoliaccessories.com/theme_stagnoli_accessories/static/src/img/tprap.webp) TPRAP TPRAP Infrared programming remote for the PRAP sensor.

Based on this, it recognises whether the object is a pedestrian, a car or a truck. **D: Does it recognise direction?** Yes, it recognises direction of travel: that's why it is also recommended as a sensor for traffic light control units (bidirectional radar). **D: How is it programmed?** With the on-board buttons or the TPRAP IR remote. **D: What warranty does it have?** 12 months for B2B purchases and 24 months for consumers, from the date of the purchase document, under Stagnoli's general terms of sale.
