Focus on Compact Short-Body M5 Model HA-5A-2

The HA series waterproof vent valve is designed to minimize maintenance requirements while maximizing equipment lifespan. Once installed, it operates continuously without power supply or manual intervention.
Its self-regulating pressure balance function reduces mechanical stress on enclosure seals, preventing long-term degradation. At the same time, its waterproof membrane protects internal components from moisture-related failures.
This significantly reduces maintenance costs and system downtime, making it a cost-effective solution for industrial and outdoor electronic systems.
It is especially suitable for infrastructure projects where long-term reliability and low maintenance are critical requirements.

Product Advantages

Focus on Compact Short-Body M5 Model HA-5A-2 9

Extremely Compact Footprint

At just 7.3mm installation height, 7.3mm body diameter, and 4mm thread length, the valve occupies approximately 40% less volume than standard M5 models. This design allows installation on device bezels as thin as 8mm—such as tablets and handheld analyzers—without affecting overall thickness or aesthetics.

Optimized Thin-Cord Sealing

To accommodate the compact structure, the O-ring CS is reduced from 2.0mm to 1.5mm, maintaining compression ratio while reducing radial reaction forces during installation—lowering the risk of cracking in thin-walled plastic housings, especially ABS/PC enclosures.

Lightweight Stainless Steel

Through topology optimization, the valve achieves maximum weight reduction while maintaining strength. Individual weight is only 65% of standard M5 models, significantly benefiting portable and wearable device weight budgets.

Uncompromised Protection

Despite its small size, IP68 and -120mbar water entry pressure ratings are identical to full-size models, ensuring core functionality is never sacrificed for compactness.
