ssqc sq-40r

sq-40t datasheet

It is impossible to count all companies producing these kind of sensors . Just use them as others do .

Worth to find frequency of transmitter - bring them together face to face , connect scope to the receiver's pins and energize transmitter by generator(even 5 V will be enough) , then tune the frequency till maximum signal level on scope screen will be shown. Note the frequency to use same in your project.
