A The position of the ventilation
must be selected so that the IP
rating of the housing is not
impaired.
Operating range for linear actuators:
The operating range for linear actuators is maximum ±45°
symmetrically to the longitudinal axis.
The usable span within the operating range is ideally 40°, but at
least 25°. The usable span should run as symmetrically to the
longitudinal axis as possible.
Operating range of rotary actuators:
The usable span is +57° to −57°, 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.
