Based on the part number **M2PHS2L-153-R2/CE**, this component is a high-precision, multi-turn **Potentiometer** (often referred to as a Helipot) typically manufactured by brands like **Sakae** or similar industrial sensor specialists. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Part Number Breakdown | Segment | Interpretation | | :--- | :--- | | **M2PHS2L** | Series designation (Multi-turn, Hybrid, Precision type) | | **153** | Resistance value: $15 \times 10^3 = \mathbf{15k\Omega}$ | | **R2** | Tolerance/Linearity specification (Standard $R = \pm 10\%$ or $2\%$ depending on context) | | **CE** | Compliance marking (Conformité Européenne) | --- ### 2. Electronic Specifications These parts are designed for analog feedback loops and control systems requiring high resolution. * **Resistance:** 15 kOhms. * **Element Type:** **Hybrid**. This usually combines a wirewound core with a conductive plastic coating. This provides the best of both worlds: the stability of wirewound and the infinite resolution/long life of conductive plastic. * **Number of Turns:** Typically a **10-turn** or **5-turn** mechanism (indicated by the "2" or "M" series sizing), allowing for very fine adjustments. * **Power Rating:** Usually between **1.0W to 2.0W** at 70°C. * **Linearity:** High precision, often $\pm 0.2\%$ to $\pm 0.5\%$. --- ### 3. Physical & Mechanical Features | Feature | Description | | :--- | :--- | | **Housing** | Metal or high-grade plastic industrial casing. | | **Shaft** | Stainless steel, usually 6mm or 1/4 inch diameter. | | **Terminals** | Gold-plated or solder-lug terminals for low contact resistance. | | **Rotational Life** | Designed for millions of shaft revolutions due to the hybrid element. | --- ### 4. Typical Applications 1. **Industrial Controls:** Used as a position sensor in actuators or valve controllers. 2. **Medical Equipment:** Fine-tuning calibration for diagnostic machinery. 3. **Test & Measurement:** Dial-adjusted voltage dividers in laboratory power supplies. 4. **Aerospace/Robotics:** Feedback sensors for joint angles or displacement. --- ### 5. Wiring Diagram (Standard Potentiometer) The device typically features 3 pins: ```text (1) CW End <--- Fixed Resistance ---> (3) CCW End ^ | (2) Wiper (Output) ```
