Ewellix electromechanical CAHB Linear actuators and mini linear actuators are engineered to operate in severe environments at temperatures from -40 to +85 °C with a maximum duty cycle of 25% and consist of robust metal gears with corrosion-resistant housings. CAHB series with 7 families of mini linear actuator, virtually maintenance-free, self-locking up to 2 times the rated load and up to IP69K/66M, covers low, medium and high loads for mobile applications, Additional design options are available like limit switches, positioning feedback and manual override. The smart CAHB-20S, CAHB-21S and CAHB-22S offer unique features at a competitive cost with integrated controller and advanced functions.
