The 27ESA103MMF50NF is a Type 23 Series spindle-operated potentiometer manufactured by TE Connectivity, designed for general-purpose control applications requiring reliable resistance adjustment. This potentiometer features a 100 kO resistance value with ±20% tolerance, a 300° mechanical rotation range, and an insulated shaft up to 50 mm in length, making it suitable for compact mounting configurations. The device operates over a temperature range of -25°C to +70°C with a maximum operating torque of 15 mNm and end stop torque of 800 mNm, ensuring smooth and durable operation. It exhibits excellent mechanical endurance with a minimum of 15,000 operations and maintains resistance stability within 15% after 1000 hours of endurance testing. The potentiometer is commonly used in audio equipment, instrumentation panels, and consumer electronics where precise volume or parameter control is required.
