Function
A synchronous motor drives the drive shaft and the camshaft via a gear train. The
attached camshaft actuates the end and auxiliary switches. The switching position of
each end and auxiliary switch can be adjusted within its working range via the
associated cam. Some of the actuator versions are equipped with electronic modules
for auxiliary functions in connection with the end and auxiliary switches or with external
devices, such as controllers (refer to «Connection diagrams»). The functions and
technical data of both lines of actuators SQN3... and SQN4... are nearly identical.
