TT ELECTRONICS / BI TECHNOLOGIES 7286R1KL.25 1kΩ 10-Turn Wirewound Potentiomter

The TT ELECTRONICS / BI TECHNOLOGIES 7286R1KL.25 is a high-precision, wirewound rotary potentiometer engineered for applications demanding exacting control and long-term reliability. This bushing-mounting component features a 10-turn adjustment mechanism, allowing for extremely fine and precise setting of resistance values. With a linear track taper, the output is directly proportional to the shaft position, making it ideal for calibration, tuning, and measurement equipment.

Constructed with a robust wirewound resistive element, this potentiometer offers a stable 1kΩ (1000 ohm) resistance with a power rating of 2W. It is built to perform consistently across a wide operating temperature range from -55°C to +125°C, ensuring functionality in challenging environments. The design includes a convenient screwdriver slot for adjustment, facilitating easy installation and calibration without the need for a dedicated knob.
