These testing systems are used for door and window seals with integrated anti-pinch systems designed to switch window or sunroof motors off if a defined load acts on the seal (if a passenger’s head or fingers are trapped). The testing system determines the load at which the electrical signal activates the safety system. The electrical signal is measured and displayed in real time in the test sequence and the system also incorporates a barcode reader for specimen identification and a horizontal positioning unit for multiple loading.
