circular potentiometer / toroidal / motorized

+++ A product of the Ruhstrat® brand +++


Stepless adjustable, these rheostats offer flexibility in the smallest place. Operation can manual or motor driven, but in either case Ruhstrat can supply modules to meet your individual requirements with drives and limit switches. All rheostats are fitted with 3 terminals and insulated axis. Therefore, they can be used as voltage divider and also as compensating resistance. Silver contacts are used for making contact. The windings are mechanically fixed and protected against influence from outside by a layer made of special cementation so that the dissipation of heat is improved.
