# Industrial Specification: Encoder

## 1. Technical Definition
A device that converts mechanical motion into electrical signals to measure position, speed, or direction in servo/stepper motor systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-10000 RPM rotational speed, -40°C to 85°C ambient temperature, 4.75-5.25 VDC supply voltage**. Failure boundary: **Exceeding 12000 RPM causes centrifugal force &gt; 1500 g, operating above 100°C causes thermal expansion &gt; 15 μm in bearing clearance, voltage spikes &gt; 7 VDC damage CMOS circuitry**, Mechanism: **Centrifugal force exceeding yield strength of encoder disk mounting (σ_yield = 250 MPa), differential thermal expansion between glass scale (α=8.5×10⁻⁶/K) and aluminum housing (α=23×10⁻⁶/K) causing optical misalignment, electrostatic discharge &gt; 2000 V damaging photodiode junctions**.

### 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.

### Q: What are the main applications of this encoder in machinery manufacturing?
**A**: This encoder is primarily used for precise position, speed, and direction measurement in servo and stepper motor systems across various industrial machinery, including CNC machines, robotics, conveyor systems, and automated manufacturing equipment.

### Q: How does the optical vs. magnetic encoder technology differ in this product?
**A**: Our encoders utilize both technologies: optical encoders use a code disk with optical glass and photodetectors for extremely high resolution, while magnetic encoders employ magnetic materials and sensors for durability in harsh environments with dust, moisture, or vibration.

### Q: What maintenance is required for these industrial encoders?
**A**: These encoders are designed for minimal maintenance with sealed aluminum alloy housings and stainless steel components. Regular cleaning of optical surfaces and periodic bearing inspection are recommended, with typical service life exceeding 50,000 hours in industrial environments.
