Industrial Sensors Waterproof Breathable Membrane
High-performance ePTFE waterproof breathable membrane designed for industrial sensors, detection systems and control equipment. It protects sensitive electronic components in harsh environments such as humidity, dust, oil mist and temperature fluctuations.
Product Overview
The microporous structure of ePTFE allows air to pass freely while blocking liquid water, dust and industrial contaminants. It effectively balances internal and external pressure, preventing condensation inside sealed sensor housings and ensuring long-term stable operation.
Core Advantages
- IP67/IP68 waterproof and dustproof protection for industrial environments
- Stable air permeability to prevent pressure imbalance in sealed enclosures
- Resistant to oil mist, weak acids and industrial chemical exposure
- Performs under wide temperature range for harsh factory conditions
- Custom die-cut sizes available for different sensor designs
Main Applications
- Industrial automation sensors
- Environmental monitoring equipment
- Factory control and detection systems
- Hydraulic and pneumatic sensor modules
- Outdoor industrial monitoring devices
