Application Scenarios of Locator Bottom Shell Pressure Balance Vent Membrane
1. Vehicle GPS Locator
Placed in the car under alternating high and low temperature for a long time, balance air pressure caused by thermal expansion and contraction of the shell to prevent condensation from corroding the main board.
2. Pet Anti-lost Locator
For outdoor rain and washing scenarios, drain water vapor inside the shell while waterproofing to avoid equipment failure caused by water ingress.
3. Electric Vehicle & Motorcycle Locator Terminal
Exposed to sun and rain, resist mud and moisture, balance cavity air pressure to prevent shell bulging and water short circuit.
4. Cargo Logistics Tracking Locator
Large temperature difference in warehousing and shipping, release internal shell pressure to avoid fogging and damp damage of components.
5. Personnel Anti-lost Location Bracelet & Name Tag
Daily hand washing and outdoor work, IP68 waterproof and pressure relief to ensure long-term stable positioning signal.
6. Construction Machinery GPS Locator
Dusty and rainy construction site environment, breathable and dustproof, balance cavity negative pressure caused by day-night temperature difference.
7. Asset Anti-theft Location Tag
Long-term static placement for outdoor equipment and containers, block rain penetration and discharge internal moisture to extend service life.
