Actuator Position Sensor

The actuator sensor serves the purpose to allow external closed loop position control, for example soft
stop or variable steering sensitivity depending on cylinder position.
For added safety the PVED-CL provides connectivity of a second sensor inputs at the same interface type.
When position sensors are mounted on the steering actuator, the signal range must be at least 5 to 10%
larger than maximum physical movement of the actuator.
The PVED-CL incorporates a printed circuit board (PCB), LVDT sensor and a solenoid operated hydraulic
H-bridge. The PCB provides connectivity to CAN and analogue signals by two 4-pin connectors each

gray connector is dedicated for CAN and electric power supply and the black for connecting analogue
devices to the PVED.
