Duff-Norton Modular Actuators
Duff Norton modular actuators are made for a variety of applications. They are custom made by matching standard actuators with electric, air, hydraulic or explosion proof drive units.
Duff Norton translating tube machine screw models feature a traveling lift nut which allows precise load positioning. Translating tube actuators are used when environmental contamination is anticipated as they have an enclosed lifting screw and translating tube. For use in locations relatively free of dust, dirt and moisture.
Optional limit switches and transducers are available on the translating tube machine screw modular actuator.
Potentiometer
The Position Feedback Potentiometer/Transducer is designed to mount on the end of any SKA6000T limit switch. Its active component is a precision potentiometer which may be used as voltage divider to provide a feedback voltage that is proportional to actuator position.
- Multiple gear ratios allow for a wide range of raises.
- Standard resistance is 5000 ohms. Other resistances are available on special order.
- Power rating: 2 watts at 40°C
- Maximum service temperature: 85°C
- Interface directly with the Model SK6300-4K Digital Position Indicator to provide a scalable readout of position. The SKA6205 series models can also be used with most motor controls that have provision for potentiometer feedback signal.
- Transducer supplied with black anodized finish as standard.
