The Connector Air Tightness Tester is a professional device used to evaluate the sealing performance of electronic connectors. Based on the differential pressure method, it detects leakage by monitoring pressure changes in a sealed system, ensuring that connectors meet waterproof and dustproof requirements such as IP67/IP68. The system provides fast, non-contact testing while protecting sensitive plated surfaces and precision interfaces.

Application

(1) Air tightness testing of electronic connectors (USB, Type-C, etc.).

(2) Leak detection for automotive connectors, battery pack connectors, and motor connectors.

(3) Waterproof and dustproof verification (IP67/IP68).

(4) Quality control in consumer electronics, automotive, and high-end manufacturing.

(5) Suitable for aerospace connectors requiring ultra-low leakage rates.

Standards

(1) IEC 60529 – Degrees of protection (IP Code)

(2) ISO 20653 – Road vehicles – Degrees of protection (IP Code)

(3) GB/T 4208 – Enclosure protection classification (reference)
