Open Type Ultrasonic Sensor- Ms-a1640h12tr have Wide Applications for Remote Controller, Burglar Alarm, Object Detectors and Range Finders. Compare with the Water Proof Type Ultrasonic Sensors, They have a Much Longer Detection Distance, But They Cant Be Used in Dirty or Wet Conditions.
Waterproof 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.
We are offering Ultrasonic Sensor. Ultrasonic is a kind of mechanical wave vibration frequency is higher than the sound wave, can by changing material in voltage under the excitation of vibration, it has a high frequency, wavelength, small diffraction phenomenon especially directional good, can be ray and directional transmission, etc.
