Piezo Air Transducers

Transmitter, receiver, or transmitter / receiver units (environmental housing)
25 kHz, 40 kHz, and 300 kHz signal frequency

Piezo Air Transducers
  • 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 transducers 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. Environmental transducers may act as both transmitter and receiver; or separate transmitter or receiver.
