Ultrasonic Sensors FAQ

Characteristics
Open-Structure type

What are the differences among ultrasonic sensors for transmitters, receivers, and dual use?

Products for transmitters are tuned to deliver the maximum sound pressure at 40kHz, while those for receivers are set to be the most sensitive at 40kHz. Sensors for dual use are designed for intermediate applications.
(Using a pair of sensors, one for transmitters and the other for receivers, lengthens the sound transmission range.)
