Door Handle System

System for Analyzing Door Handles

Application Description

In the production process of a vehicle door handle, the electrical functions of the component are to be tested. The mechanical testing of the operation of the door handle is performed by a PLC-controlled test system. In addition to the mechanical test, the electrical parameters: “serial data stream” and “impedance of the antenna” are to be analysed.

The test system described here fulfils the following tasks: Testing door handles by measuring the antenna over LCR meter. A distinction is made between “door handle opened or closed actuated”. Communication with the PLC of the machine takes place via DIO interface.
