Ultrasonic

Ultrasonic Sonar Ranging IC - PW0268 Features: • Operates in 6 – 10 V single voltage • Wide operation frequency range up to 250KHz • Temperature controlled oscillator traces resonant frequency drift of transducers • Built-in 32 steps time controlled gain amplifier • Built-in band pass filter of less external tuned components • Bi-direction I/O for both driving pulse and echo • Adjustable system clock for various detection range • Suitable for car reversing aids, tape measurements and other sonar ranging applications.

The SRM400 is a sonar ranging module utilizing our new developed Sonar Ranging IC, PW-0268, which can work with all our PT or EP type transducers. SRM400 provides as a shortcut to develop car reversing systems or some other distance measurement systems for design engineers who are not very familiar with analog circuit and/or the operation of ultrasonic transducers. By using this module engineers can focus firstly on the other fields of digital circuit and software designs as well as some other mechanical issues. After first stage then you can either design your own analog circuit based on the module construction or consult with factory for making your own module for your special needs.

The couple of transducer 250ET/R250 is suitable for outdoor low cost applications where the minimum measurable distance is a fundamental parameter or anyway for simple detection of people and objects passing.

The couple of transducer 250ST/R240 is suited for low cost applications where the minimum measurable distance is a fundamental parameter or anyway for simple detection of people and objects passing.
