The 23ESA103MMF50AF is a Type 23 Series spindle-operated potentiometer manufactured by TE Connectivity, featuring a 100 kO linear resistance element with ±20% tolerance and a 50 mm insulated shaft. It delivers 0.4 W at 40°C and exhibits a mechanical rotation of 300° with an operating torque of 15 mNm maximum and end stop torque of 800 mNm maximum. The device operates reliably across a temperature range of -25°C to +70°C, with mechanical endurance rated at 15,000 operations minimum and resistance change limited to 15% after 1000 hours of endurance testing. This rugged potentiometer is ideal for control applications in industrial equipment, audio systems, and consumer electronics where reliable, customizable spindle-based adjustment is required.
