# Industrial Specification: Rotary Encoder/Resolver

## 1. Technical Definition
A sensor that converts the angular position or motion of a shaft to an analog or digital signal.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10000 RPM with 0.1° angular resolution at 25°C ambient temperature**. Failure boundary: **Mechanical failure at &gt;12000 RPM centrifugal force, electrical failure at &gt;85°C junction temperature, signal degradation at &gt;0.5mm radial shaft play**, Mechanism: **Bearing fatigue from centrifugal loading exceeding 9.8×10^3 N at 12000 RPM, semiconductor thermal runaway at 85°C exceeding silicon bandgap stability, Hall-effect sensor misalignment from shaft eccentricity &gt;0.5mm**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$

### Q: What is the difference between a rotary encoder and a resolver?
**A**: Rotary encoders typically output digital signals and are ideal for high-speed applications, while resolvers output analog signals and excel in harsh environments with extreme temperatures or vibrations common in machinery manufacturing.

### Q: What materials make these encoders suitable for industrial environments?
**A**: Our encoders feature aluminum alloy and stainless steel housings for corrosion resistance, precision bearings for durability, and glass/magnetic code discs for accurate position detection in demanding machinery applications.

### Q: How do I maintain a rotary encoder in heavy equipment?
**A**: Regular inspection of bearings and housing seals, keeping the code disc clean from contaminants, and monitoring signal output consistency will ensure optimal performance. Most industrial encoders are designed for minimal maintenance.
