# Industrial Specification: Environmental Housing

## 1. Technical Definition
Protective enclosure designed to shield motion sensor components from environmental factors.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **-40°C to +85°C, IP67 rating (1m immersion for 30min), 0-100% relative humidity non-condensing**. Failure boundary: **Seal failure at 125°C (EPDM rubber glass transition), housing deformation at 150°C (polycarbonate HDT), IP rating breach at 1.2m water pressure**, Mechanism: **Thermal expansion coefficient mismatch (α_polycarbonate=65×10⁻⁶/K vs α_aluminum=23×10⁻⁶/K) causing seal compression loss at ΔT&gt;100K, hydrolytic degradation of polycarbonate at 95°C/95%RH**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| UV radiation exposure at 0.8W/m²/nm for 5000h | 8 | Polycarbonate yellowing (ΔYI&gt;10) reducing IR transmission below 85% at 8-14μm | Co-extruded UV-stabilized layer with 2% benzotriazole absorber, aluminum vapor deposition on exterior surfaces |
| Thermal cycling between -40°C and +85°C at 10°C/min for 1000 cycles | 8 | Gasket compression set exceeding 25% (per ASTM D395), leading to IP rating degradation to IP54 | Dual-durometer silicone gasket (shore A70 exterior/shore A50 interior) with compression limit stops at 30% deflection |

## 3. Key Technical Parameters

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What environmental factors does this housing protect against?
**A**: This housing shields motion sensor components from moisture, dust, temperature extremes, and physical impacts using sealed construction and durable materials like aluminum alloy and engineering plastics.

### Q: What materials are used in this environmental housing?
**A**: The housing is constructed from engineering plastics for lightweight durability, aluminum alloy for structural strength, and stainless steel for corrosion resistance in harsh environments.

### Q: Does this housing maintain sensor functionality while providing protection?
**A**: Yes, the transparent window allows unobstructed sensor operation while the mounting bracket ensures proper alignment and the sealing gasket maintains environmental protection without interfering with performance.

## 6. Manufacturing Compliance
- ISO 14001:2015 ENVIRONMENTAL MANAGEMENT SYSTEMS
- CE MARKING FOR CONSTRUCTION PRODUCTS REGULATION (EU) NO 305/2011
