Anti-Trap Sensors

An anti-trap sensor is installed along the top of each window aperture, just outside the travel path of the window glass. Each anti-trap sensor consists of a rubber covered contact strip connected to ground and to a power supply from the door (front windows) or BCU (rear windows). When the anti-trap sensor is pressed the resistance across the contact strip is reduced. If a window is being closed and the door /BCU detects a drop in resistance across the associated anti-trap sensor, it immediately (in less than 20 milliseconds) reverses the window.
