Data Sheet for Precision PotentiometerMultiturn Wirewound Potentiometer The ALS25 series potentiometers are used as multiturn sensors with outstanding linearity and resolution for measuring ranges from 3 to 20 revolutions. ■ Multiturn 3..20 turns ■ Optional rear shaft ■ Optional tandem version ■ On request limit switch (CW, CCW) Despite the compact housing diameter of only 25 mm, the potentiometer offers an angular range of up to 20 rev. and exceptional additional options such as galvanically isolated limit switches for the limit positions and up to 5 taps of the resistance element. For applications with the requirement for redundant and / or galvanically isolated signals, the tandem variant can be selected. MEGATRON Elektronik GmbH & Co.
