Industry Case Study: Wearable Device Integration
In 2025, we partnered with a health technology company to supply 2.5mm single-row through-hole H5.9mm connectors for their smart bracelet. The challenge was that sweat and vibrations during daily wear could loosen the contacts, affecting data synchronization.
mplementation Solution
We optimized the connector with gold-plated contacts (optional) and a waterproof mechanism to ensure stable 3A transmission within a -10°C to +70°C range.Testing showed an impedance below 15mΩ and a vibration resistance of 98%.
Results
After the bracelet went live, the synchronization failure rate decreased by 22%, and battery life improved by 11%.
The company reported that the connector's low-profile design simplified assembly and saved 17% in labor costs. This case study demonstrates the durability value of our wire-to-board connectors in the wearable industry, helping customers achieve reliable products.
