Operating range for linear actuators:
The operating range for linear actuators is ±45° symmetrically to
the longitudinal axis. The usable span within the operating range
is at least 25° (recommended figure 40°). The usable span does
not necessarily need to run symmetrically to the longitudinal
axis.
Operating range of rotary actuators:
The usable span is 90°, which must be entirely within the
measuring range, but does not necessarily need to run
symmetrically to the longitudinal axis.
Note
During installation make sure that the actuator travel or rotation
angle for position feedback is implemented correctly.
