Product Description
55.5kHz 15.5mm Ultrasonic Distance Measurement Sensor
Model: TM-A55.5-15.5TR
This enclosed ultrasonic sensor utilizes piezoelectric effect to convert electricity to mechanical vibration, forming ultrasonic waves for automotive parking assist applications. With no coil contained, electromagnetic interference is greatly reduced.
Key Features
- Low power consumption
- High reliability
- Excellent waterproof performance and weatherability
Applications
- Reversing detection systems
- Automotive parking assist systems
- Blind spot information systems
