Industrial R40100 Rotary Potentiometer Sensor

R40100 Rotary Potentiometer Sensor is an industrial‑grade position sensor that converts shaft rotation into a variable resistance, delivering a precise feedback signal for automated control systems. Sold under the SKAN-A-MATIC Clarostat brand, it sits in Honeywell’s Clarostat portfolio of rotary potentiometers that use conductive-plastic or cermet resistive elements to provide smooth position sensing across harsh industrial environments. This type of potentiometer yields a voltage or current output that corresponds to the angle of rotation, enabling reliable position feedback for machinery controls, automation panels, and process equipment. Retail listings for the model show variants configured for 115 VAC operation, underscoring its industrial interface requirements. Clarostat, now part of Honeywell Sensing and Productivity Solutions, has a long history of motion and position sensing, and the R40100 exemplifies that legacy by offering rugged position sensing for demanding environments. The R40100 family is associated with SKAN-A-MATIC assemblies, reflecting Clarostat/Skan-A-Matic sensor solutions used in industrial instrumentation.
