The Tifu SPK2500 potentiometer sensor datasheet provides specifications such as size, resolution, lifespan, linearity, and electrical parameters.
The SPK2500 series is a high‑performance, compact potentiometer sensor with a plastic housing, stainless‑steel shaft and bearings, and a multi‑contact precious‑metal brush. It offers high accuracy, long life (50 × 10⁶ cycles), excellent linearity (±0.3 %), and a resolution better than 0.01°, making it suitable for measurement, control, and instrumentation applications.
The datasheet lists detailed mechanical and electrical parameters, environmental limits, and recommended accessories such as couplings and signal converters. It also includes model definitions, ordering codes, and installation instructions (three M2.5 screws with washers). This manual is written in Chinese.
