DESCRIPTION

The SBPSUSL45 is an ultrasonic carpark sensor designed to detect the presence of vehicles in parking bays and indicate their status through integrated high-brightness RGB LEDs visible at 360 degrees. The sensor operates at 40 kHz ultrasonic frequency with a 45-degree detection angle, mounted at a height between 2.2 to 2.4 meters with a detection depth of 1.5 meters. It features automatic temperature compensation for stable operation across -40°C to 70°C, supports 8 selectable LED colors for status indication (vacant, occupied, booked, disabled), and connects via Dupline® 3-wire bus protocol with power supply of 20-28 Vdc. The sensor provides a total response time of 4.0 seconds at 8-measure filter and includes local calibration capability through a dedicated button. This 2-in-1 integrated solution simplifies installation in parking guidance systems by combining detection and visual indication in a single unit, reducing wiring complexity and improving driver visibility.
