An ultrasonic sensor in a compact housing, with 20-450cm detection range.
Ultrasonic transducers are used in vehicles as parking assistance. The ultrasonic transducer sends out short ultrasonic impulses which are reflected by barriers. The echo signals are registered by the sensor and are evaluated by a central control unit.
This ultrasonic parking sensor from Bosch is very compact with its very few components meaning it is manufactured at low cost. The sensor is made with one electronic board, including a Bosch transceiver integrated circuit (IC) that drives the output of the Epcos/TDK transformer and evaluates the reflected signal. The transducer itself is made of a lead zirconate titanate (PZT) membrane and silver electrodes.
Based on a complete teardown analysis of the Bosch ultrasonic sensor, the report provides the bill-of-material (BOM) and manufacturing cost. A physical analysis and a manufacturing cost estimation of the Bosch transceiver IC are also available in this report.
