Lead-Free Piezo Benders
PUI Audio's AB series lead-free benders are designed with a range of resonant frequencies and mounting configurations
PUI Audio's AB series lead-free piezo benders comply with all RoHS regulations and are available in three sizes, including 20 mm, 27 mm, and 35 mm. They are designed with a range of resonant frequencies and mounting configurations.
These lead-free piezo discs have the same technical capabilities as traditional ones but with a slimmer profile. This advancement opens possibilities in the medical, industrial, automotive, and consumer sectors. Lead-free benders are essential in medical and other sensitive environments where direct contact with humans is likely.
These piezo benders offer the perfect solution where space is at a premium, multiple tones are required, and high output and low power consumption are necessary. These externally driven elements are found in all varieties of products, from media players to smoke detectors. They can even be used as switches and contact microphones.
