# Industrial Specification: Emergency Stop

## 1. Technical Definition
A safety control device that immediately halts machine motion when activated.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **24-48 VDC at 2-10 A continuous, 100 A peak for 100 ms**. Failure boundary: **Contact resistance exceeds 50 mΩ at rated current, insulation breakdown at 1500 VAC for 1 minute**, Mechanism: **Contact welding due to inrush currents exceeding 100 A, dielectric breakdown of 2.5 mm polycarbonate housing at 6 kV/mm**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contact contamination by 0.1 μm conductive particles | 8 | Contact resistance increases to 500 mΩ causing voltage drop &gt;2.4 V | IP67 sealed enclosure with 0.5 μm HEPA filtration |
| Mechanical fatigue from &gt;100,000 actuation cycles at 50 N force | 8 | Spring force degrades below 40 N causing &gt;5 mm overtravel | DIN EN 60947-5-5 compliant design with 1,000,000 cycle rating |

## 3. Key Technical Parameters
