TT ELECTRONICS / BI TECHNOLOGIES Precision Potentiometer, Wirewound, 7/8 Inch,

The TT ELECTRONICS / BI TECHNOLOGIES 7286 Series Precision Potentiometer is a high-quality, wirewound component designed for demanding applications where accuracy and reliability are paramount. Featuring a robust bushing-mount design and a 10-turn adjustment mechanism, it offers precise and repeatable control over electrical resistance.

This 100kΩ potentiometer utilises a linear track taper, ensuring a direct, proportional relationship between shaft rotation and resistance change. It is rated for 2W power handling and includes a convenient screwdriver slot for adjustment, making it suitable for calibration and fine-tuning in fixed installations. The construction incorporates a turret terminal type for secure electrical connections.

Built for durability, the potentiometer boasts an impressive operating temperature range from -55°C to 125°C, allowing it to perform reliably in harsh environmental conditions. It features a low maximum backlash of 1° and benefits from IP50/IP66 protection ratings, offering defence against dust ingress and powerful water jets. Its dielectric strength is rated at 1000Vrms, ensuring safe operation in high-voltage scenarios.

With a resistance tolerance of ±5% and a temperature coefficient of ±20ppm/°C, this component provides stable and predictable performance. Its wirewound resistor technology contributes to low maximum noise (100Ω) and minimal end voltage deviation (0.25% maximum), making it an excellent choice for precision circuits in industrial controls, test equipment, and instrumentation.
