# Industrial Specification: Barcode/QR Scanner

## 1. Technical Definition
An optical device that reads barcode and QR code labels on chemical drums to capture identification and tracking data.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m (reading distance), 0-50°C (operating temperature), 85-264 VAC (input voltage)**. Failure boundary: **Laser diode degradation at 10,000 hours continuous operation, CMOS sensor failure at 60°C junction temperature, lens contamination exceeding 30% surface coverage**, Mechanism: **Laser diode quantum efficiency degradation due to non-radiative recombination centers, CMOS sensor thermal runaway at 60°C due to increased dark current, optical scattering from particulate accumulation on polycarbonate lens surfaces**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.
