Hydraulic and electric actuators have a very rigid behavior and can only be made to act in a compliant manner through the use of relatively complex feedback control strategies.
16.
The enclosure protection types are defined according to the IP codes of EN 60529 . The basic versions of most electric actuators are designed to the second highest enclosure protection IP 67.
17.
Electric controllers are easier and cheaper to fit to towing vehicles but electric actuators at present can only be fitted to drum brakes, whilst hydraulic systems are needed for disc brakes.
