# Industrial Specification: Position Encoder

## 1. Technical Definition
A sensor device that converts mechanical position into electrical signals for precise measurement and control.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10000 RPM rotational speed, ±0.001° angular resolution, -40°C to 85°C ambient temperature**. Failure boundary: **Exceeding 12000 RPM causes centrifugal force &gt; 1500g, leading to encoder disk deformation &gt; 50μm**, Mechanism: **Hall effect sensor saturation at magnetic flux density &gt; 1.2T, causing signal distortion beyond 0.005% linearity error**.

### 2.1 Analytical Physics Model
Governed by the **Combined Measurement Uncertainty**:

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$  
> **Engineering Impact**: Defines the precision confidence interval for inspection.
