"High quality Motorized Potentiometers"
Motorized Potentiometers are used in a variety of industrial automation and process control applications such as speed controls, flow meters, tensioning motors, etc., by allowing automatic remote control in addition to use of a manual control knob. A geared servo motor, slip clutch and single or multi-turn potentiometer form the motor pot. The different gear boxes in the motorized potentiometer enabling run-up and run-down time settings varying from 10 to 300 seconds. OLC manufactures all its motorized potentiometers from the highest quality components available. The main characteristics of our motorized potentiometers are smooth performance, high linearity and resolution, reliable terminations and durability.
Series MC (DC) and MAC (AC) models are available with single turn or ten turn, wirewound or conductive plastic, and single or multiple gang potentiometer. The slip clutch protects the potentiometers end stops, and allows for manual adjustment.
Motor controlled potentiometers give wide latitude in speed control.
Replacement units for old ETI motorized potentiometers available, please check the bottom of page for a list of model numbers. Please call if you do not find the model number below. We can also repair old ETI motorpots built in the 1980 and 1990's.
