# Industrial Specification: Encoder/Resolver

## 1. Technical Definition
A sensor that converts mechanical motion into electrical signals for position, speed, or direction feedback in control systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10000 RPM rotational speed, -40°C to 125°C temperature, 5-24 VDC supply voltage**. Failure boundary: **15000 RPM centrifugal force causing bearing deformation, 150°C thermal degradation of Hall-effect sensors, 30 VDC dielectric breakdown of insulation**, Mechanism: **Centrifugal force exceeding yield strength of bearing materials (σ_yield = 250 MPa for 52100 steel), Arrhenius equation thermal aging (E_a = 0.7 eV for epoxy encapsulation), Fowler-Nordheim tunneling in oxide layers at 6 MV/cm electric field**.

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

> **Primary Equation**: $u_c = \sqrt{\sum u_i^2}$

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the difference between an encoder and a resolver?
**A**: Encoders use optical or magnetic disks to provide digital position feedback, while resolvers use electromagnetic induction to deliver analog signals. Resolvers are more robust in harsh environments, while encoders offer higher resolution.

### Q: What materials are used in encoder/resolver construction?
**A**: Our sensors feature aluminum housings for durability, stainless steel shafts for corrosion resistance, and high-quality PCBs with sensing elements. Optical versions use precision code disks, while magnetic versions use magnetic disks.

### Q: How do I choose between optical and magnetic encoders?
**A**: Optical encoders provide higher resolution and accuracy for clean environments, while magnetic encoders are better for dusty, humid, or high-vibration applications where contamination resistance is critical.

## 6. Manufacturing Compliance
