Piezo Air Transducers
Transmitter, receiver, or transmitter / receiver units (environmental housing)
25 kHz, 40 kHz, and 300 kHz signal frequency
- high sensitivity
- excellent sound pressure
- low cost
- 10 mm to 25 mm diameter
- matched pairs available
- custom specifications welcomed
- competitive pricing
- fast delivery
Typical Applications of Piezoelectric Transducers
- automobile sensors
- proximity sensors
- object detectors
- level sensors
- remote controls
- motion detectors / intruder alarms
- pest deterrents
- toys / games
Our air transducer applications consist of a piezoelectric ceramic element, mounted in an aluminum, plastic, or environmental (sealed) housing. These piezoelectric transducers offer high sensitivity, superb sound pressure level (SPL), and stable electrical and mechanical characteristics, at a choice of bandwidths and vary in frequencies and amplitudes. Environmental transducers may act as both transmitter and receiver; or separate transmitter or receiver.
