Principle of operation
The Type SAM ... Electric Linear Actuators are
equipped with reversible a.c. or three-phase
a.c. motors. The rotary motion of the motor is
transferred to the actuator stem via a gear unit
and the corresponding transfer elements
where it is converted into a linear "On-Off"
motion.
In case the electrical power fails, you can
operate the actuator manually.
Special features
– Nominal thrust from 2 to 25 kN
– Rated travel 15, 30, 60 or 120 mm
– Speed of response 13.5 to 50 mm/min
– A.c. motor 230 V~, 50 Hz
or
three-phase a.c. motor 400 V~, 50 Hz
– Degree of protection IP 65
