- Hazardous substances can pose significant risks to human health and our planet. Kingstate has been working on sustainable product design to reduce lead usage and developing a new PB-free series of piezo-ceramic elements and piezo buzzers. Typically, Pb contains over 500,000ppm in 23mm piezo ceramic elements, but our edgy Pb-free elements are less than 1,000ppm which is compliant with RoHS 2.0 without exemption.

•Normal piezo ceramics Pb content > 500,000ppm
•RoHS 2.0 compliant without exemption
•Measured and tested by SGS
