It is pulse-width modulated and has adjustable acceleration/deceleration ramping. The threshold, full stroke forward and full stroke reverse outputs are adjustable. The KE07205 is a direct replacement for the MXX458 or the MXX1139. It is the same as the KE07203 except it has a 3.4 volt reference for null.
