# Industrial Specification: Solenoid/Pneumatic Actuator

## 1. Technical Definition
A hybrid actuator combining solenoid and pneumatic mechanisms for rapid valve control in industrial automation systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-10 bar pneumatic pressure, 12-24 VDC solenoid voltage, -20°C to +85°C ambient temperature**. Failure boundary: **Pneumatic pressure exceeding 12.5 bar causes diaphragm rupture, solenoid coil insulation breakdown at 130°C winding temperature, mechanical fatigue failure at 1,000,000 actuation cycles**, Mechanism: **Diaphragm material yield strength (EPDM rubber: 15 MPa) exceeded at 12.5 bar differential pressure, solenoid coil insulation class F (155°C) thermal degradation at 130°C continuous operation, brass valve stem fatigue failure at 1,000,000 cycles due to cyclic stress concentration**.

### 2.1 Analytical Physics Model
Governed by the **Pneumatic Actuator Theoretical Force**:

> **Primary Equation**: $F = P \cdot A \cdot \eta_{eff}$  
> **Engineering Impact**: Calculates real-world pushing/clamping force for rejectors.
