# Industrial Specification: Field-Side I/O Connectors

## 1. Technical Definition
Electrical connectors located on the field side of an I/O interface board that provide physical connection points for external sensors, actuators, and other field devices.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-60 VDC, -40°C to +85°C, 0-100% relative humidity (non-condensing)**. Failure boundary: **Contact resistance &gt; 50 mΩ, insulation resistance &lt; 100 MΩ at 500 VDC, dielectric breakdown at &gt; 1000 VAC**, Mechanism: **Electrochemical migration due to ionic contamination under humidity, fretting corrosion from micromotion at contact interfaces, dielectric breakdown from partial discharge in contaminated insulation**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Galvanic corrosion between dissimilar metals (copper alloy contacts vs aluminum housings) in presence of chloride ions | 8 | Contact resistance increase beyond 50 mΩ causing signal attenuation &gt; 3 dB | Gold plating (0.76 μm minimum) on contact surfaces with nickel underplate (2.54 μm), hermetic sealing with IP67 rating |
| Thermal cycling stress (ΔT &gt; 100°C) causing coefficient of thermal expansion mismatch between polymer housing (CTE 60-80 ppm/°C) and metal contacts (CTE 17 ppm/°C) | 8 | Contact retention force reduction below 15 N causing intermittent connections | Stress-relief design with silicone grommets (shore A 40), controlled impedance mating geometry with 0.5 mm chamfer |
