Interior Cabin Protection

The 509U Ultrasonic Sensor helps protect the vehicle interior by monitoring movement inside the cabin area.

Air Disturbance Detection

The sensor detects movement by sensing air disturbance and pressure changes inside the vehicle.

Protection Beyond Glass Breakage

The 509U helps detect entry attempts that may not involve broken glass, adding another layer of intrusion detection.

Best with a Secured Cabin

For best performance, the 509U is most effective when the vehicle’s doors, windows, and sunroof are fully closed.

Designed for Enclosed Vehicles

The 509U is not recommended for convertible vehicles, making it better suited for enclosed cabin applications.
