The **MHO+23FCG-R** refers to a high-precision, multi-turn wirewound potentiometer, typically manufactured by brands like **Sakae** or similar precision component specialists. These parts are designed for industrial control systems where high reliability and exact resistance adjustments are required. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | Precision Multi-turn Wirewound Potentiometer | | **Number of Turns** | 10-Turns (standard for the MHO series) | | **Resistance Range** | Typically 100Ω to 100kΩ (specific to the suffix) | | **Linearity Tolerance** | ±0.2% to ±0.5% (Independent Linearity) | | **Power Rating** | 2.0 Watts (at 40°C) | | **Rotational Life** | ~1,000,000 shaft revolutions | | **Mounting Type** | Bushing Mount (Panel mount) | --- ### 2. Breakdown of the Model Code While numbering can vary slightly by manufacturer, the code generally breaks down as follows: * **MHO**: Series designation (Multi-turn, High-precision, Oil-filled or specific housing style). * **23**: Diameter of the body (typically ~22mm - 23mm). * **F**: Indicates a specific terminal style or front-mounting feature. * **C**: Circular/Clamped design features. * **G**: Gold-plated terminals or specific contact material for low noise. * **-R**: Often denotes "RoHS Compliant." --- ### 3. Internal Construction and Materials The device consists of several critical electronic and mechanical parts: * **Resistance Element:** A high-quality resistive wire (often Nickel-Chromium alloy) wound around a ceramic or fiberglass mandrel. * **Wiper (Contact):** A precious metal multi-fingered contact that slides along the winding to vary resistance. * **Shaft:** Usually stainless steel, supported by bearings to ensure smooth torque and minimal "play" (mechanical backlash). * **Housing:** Glass-filled nylon or diallyl phthalate (DAP) for high insulation resistance and thermal stability. --- ### 4. Typical Applications These parts are not found in consumer electronics but rather in specialized equipment: 1. **Medical Equipment:** Precision voltage dividers for diagnostic imaging. 2. **Aerospace:** Control surface positioning sensors. 3. **Industrial Automation:** Manual calibration points for motor speed controllers or temperature regulators. 4. **Test & Measurement:** Calibration standards in laboratory power supplies. --- ### 5.
