## Summary description

Wired reverse parking sensor BLOW CPB4 in silver finish, with a 22 mm mounting diameter. Designed to detect obstacles behind a vehicle and assist with parking maneuvers, this compact sensor integrates into bumpers and works as part of a parking aid system. Suitable for passenger cars where a small-diameter ultrasonic/proximity sensor is required.

## Long description

The BLOW reverse parking sensor CPB4 (silver) is a wired ultrasonic proximity sensor with a 22 mm mounting diameter designed for integration into vehicle bumpers. Its compact form factor and silver finish allow discreet installation while providing continuous detection of obstacles behind a car. The sensor is intended to operate as part of a parking aid system, transmitting distance information to the vehicle’s control unit or display module to support safer and more precise reversing maneuvers.
Advantages
The CPB4 sensor offers a small-diameter design that fits narrow bumper cutouts and conserves space during installation. Its wired connection ensures stable signal transmission and compatibility with many aftermarket and factory parking systems that accept ultrasonic inputs. The silver finish provides a neutral, low-contrast appearance on a range of bumper colors, and the robust housing is engineered for repeated outdoor exposure and typical automotive conditions.
Suitable for
Installation in passenger car rear bumpers where a compact ultrasonic sensor is required
Integration with wired aftermarket or OEM parking assist systems
Replacement of worn or damaged small-diameter proximity sensors
Key specifications
Mounting diameter: 22 mm
Connection type: wired
Sensor type: ultrasonic / proximity detection
Finish: silver
Typical application: rear parking obstacle detection
How to use
Locate a suitable mounting position in the rear bumper and create a 22 mm cutout following vehicle-specific guidelines. Connect the sensor wiring to the parking system harness or control unit according to the system’s wiring diagram, ensuring secure and weatherproof connections. Position the sensor so its face is flush with the bumper surface for accurate detection, then test the system by slowly reversing toward an obstacle and verifying distance response and alarm indicators. Adjust or recalibrate the parking system if required by the vehicle or aftermarket module.
Usage recommendations
To maintain reliable operation, keep the sensor face clean from mud, snow, and ice. During installation use appropriate sealing grommets and corrosion-resistant connectors. If used in colder climates, inspect the sensor regularly for build-up that could impair ultrasonic detection and perform system tests after heavy impacts or bumper repairs.
