piezo sensor applied in parking sensor

applied in parking sensor,excellent mechanical and physical performance, it can replace the similar products from Japanese MURAT

(1) the piezoelectric ultrasonic is applied in parking sensor system. there're piezoelectric component in the case and it can transfer the electric power into mechanical power. so generate the ultrasonic wave to ditect the distance bettween two objects.

(2) the raw material is PZT, we're the original manufacturer factory of the PZT products thus we have our own different formula of PZT for different function.

(3) it is could be customized in accordance with the customers' demand.

(4) excellent cost-effective, we can supply with the best reliable price under a high quality. we can keep the rapid delivery time.

(5) specific technical data:
