SQ 05.2 SQ 14.2/SQR 05.2
Made of spheroidal cast iron with two or three bores for fixing a lever arrangement. Considering the in-
stallation conditions, the lever may be mounted to the output shaft in any desired position.
Two ball joints matching the lever, including lock nuts and two welding nuts, suitable for pipe according
to dimension sheet
Base with four holes for fastening screws
Counter gear mechanism for end positions OPEN and CLOSED
Turns per stroke: 1 to 500 (standard) or 1 to 5,000 (option)
Standard: Single switch (1 NC and 1 NO) for each end position, not galvanically isolated
Options: Tandem switch (2 NC and 2 NO) for each end position, switches galvanically isolated
Triple switch (3 NC and 3 NO) for each end position, switches galvanically isolated
Intermediate position switches (DUO limit switching), adjustable for each direction of op-
eration
Torque switching adjustable for directions OPEN and CLOSE
Standard: Single switch (1 NC and 1 NO) for each direction, not galvanically isolated
Option: Tandem switch (2 NC and 2 NO) for each direction, switches galvanically isolated
Standard: Silver (Ag)
Option: Gold (Au), recommended for low voltage actuator controls
Potentiometer or 0/4 20 mA (electronic position transmitter)
Continuous indication, adjustable indicator disc with symbols OPEN and CLOSED
Blinker transmitter (optional for modulating actuators)
Standard: Self-regulating PTC heater, 5
Options: 24 48 V AC/DC (for actuators with 3-phase AC/1-phase AC/DC motors)
or 380 400 V AC (for actuators with 3-phase AC motors)
A resistance type heater of 5 W, 24 V AC is installed in the actuator in combination with AM or AC actu-
ator controls.
A resistance type heater of 5 W, 24 V AC is installed in the actuator in combination with AC actuator
controls.
Indoor and outdoor use permissible
Any position
≤ 2,000 m above sea level
> 2,000 m above sea level on request
Refer to actuator name plate
Up to 100 % relative humidity across the entire permissible temperature range
Standard: IP68 with AUMA 3-phase AC motor/1-phase AC motor
For special motors differing enclosure protection available (refer to motor name plate)
Option: Terminal compartment additionally sealed against interior of actuator (double sealed)
According to AUMA definition, enclosure protection IP68 meets the following requirements:
Depth of water: maximum 8 m head of water
Duration of continuous immersion in water: Max. 96 hours
Up to 10 operations during immersion
Modulating duty is not possible during immersion
For exact version, refer to actuator controls name plate.
Pollution degree 4 (when closed), pollution degree 2 (internal)
2 g, 10 to 200 Hz (AUMA NORM), 1 g, 10 to 200 Hz (for actuators with AM or AC integral controls)
Resistant to vibration during start-up or for failures of the plant. However, a fatigue strength may not be
derived from this. Valid for part-turn actuators in version AUMA NORM and in version with integral actu-
ator controls, each with AUMA plug/socket connector. Not valid in combination with gearboxes.
