# Industrial Specification: Linear Encoder

## 1. Technical Definition
A precision measurement device that converts linear position into digital signals for feedback control in motion systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 mm displacement, ±0.5 μm resolution, 0-60°C ambient temperature, 0-95% relative humidity non-condensing**. Failure boundary: **Exceeding 120°C internal temperature, surpassing 100 m/s² vibration amplitude at 2000 Hz, exposure to &gt;1000 lux optical interference, &gt;50 μm particulate contamination**, Mechanism: **Photodiode array saturation at &gt;1000 lux ambient light, piezoelectric crystal depolarization above Curie temperature of 120°C, Moiré fringe pattern distortion from particulate-induced refractive index changes of Δn&gt;0.01**.

### 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.

- **Caution**: 

### Q: What is the difference between optical and magnetic linear encoders?
**A**: Optical encoders use glass scales with light patterns for ultra-high precision in clean environments, while magnetic encoders use magnetic materials and are more resistant to dust, debris, and harsh conditions with slightly lower resolution.

### Q: How do I choose the right linear encoder for my machinery application?
**A**: Consider your required resolution (precision), environmental conditions (clean vs. harsh), mounting constraints, travel length, and signal output type. Optical glass scales offer highest precision, while magnetic encoders provide better durability in challenging environments.

### Q: What maintenance is required for linear encoders in industrial settings?
**A**: Regular cleaning of optical scales with approved solvents, inspection of protective housings for damage, checking cable connections for wear, and ensuring proper alignment between read head and scale. Magnetic encoders typically require less maintenance than optical versions.
