Mini Waterproof Ultrasonic Transducer Dual Use Transmitter And Receiver

OD 8*8mm sensor waterproof ultrasonic transducer aluminum case with cable connector

Enclose Ultrasonic SensorTM-A0808TR40

Water proof type ultrasonic sensors were widely used for parking sensors, proximity sensors and level sensors, etc. With perfect seal these sensors can be used in a relatively poor environment such as dust and humidity.

The ultrasonic transducer utilizes piezoelectric effect to convert electricity to mechanical vibration and form ultrasonic waves. Therefore no coil is contained and electromagnetic interference can be greatly reduced. The ultrasonic wave has excellent directivity and strong penetrability, and is interfered by neither the dust and electromagnetic fields in the air, nor the color and temperature at object surfaces.
