Parking reverse sensor BLOW 19 mm black lenses, parking aid sensor 19mm

BLOW parking reverse sensor with 19 mm black lens is a compact ultrasonic-style proximity sensor designed for installation in vehicle bumpers. Intended as a parking aid, the sensor detects obstacles behind the vehicle and provides distance information to compatible parking systems or aftermarket alarm units. The small 19 mm diameter housing allows discreet mounting while maintaining reliable short-range detection for safer reversing maneuvers.

Advantages

The sensor's compact form factor and black lens make it suitable for unobtrusive installation in many bumper designs. It uses ultrasonic detection to sense nearby objects and transmit signals to compatible control units, supporting consistent performance in typical parking scenarios. Its straightforward design facilitates integration into existing parking systems or aftermarket kits without large modifications to the vehicle bodywork.

Suitable for

• Standard passenger cars and small vans requiring aftermarket parking aids
• Retrofit installations into bumpers where a 19 mm cutout is available
• Integration with compatible parking control units, alarm systems, or display modules
• Drivers seeking additional rear obstacle detection during reversing and low-speed maneuvers

Key specifications

• Sensor type: ultrasonic proximity sensor for reversing assistance
• Lens diameter: 19 mm
• Lens color: black
• Mounting: flush or semi-flush installation in bumper panel with 19 mm cutout
• Typical use range: short-range obstacle detection suitable for parking distances
• Compatibility: designed for integration with compatible vehicle parking systems and aftermarket alarm/control units

How to use

Install the sensor into a prepared 19 mm diameter hole in the bumper at the recommended mounting height and orientation for rear obstacle coverage. Connect the sensor wiring to the compatible parking control unit or alarm system following the control unit manufacturer's wiring diagram and observe proper polarity and shielding practices where specified. After mechanical and electrical installation, perform system calibration or detection testing according to the parking system instructions to verify detection zones and adjust control settings if available.

Usage recommendations

Position sensors evenly across the rear bumper to ensure overlapping detection zones and minimize blind spots. Avoid mounting near large air gaps or behind thick trim that could obstruct ultrasonic pulses. Periodically inspect sensor lenses for dirt or damage and clean with a soft cloth to maintain reliable detection performance.
