Real-world case study: IoT device integration
In 2026, we partnered with a smart home company to provide 1.25mm single-row through-hole connectors for their wireless sensor network. The challenge was that space constraints in battery-powered devices and frequent connections could lead to signal instability, impacting data acquisition.
Implementation
The connector was optimized with optional gold plating and low-power mechanisms to ensure stable 1A transmission over a range of -10°C to +70°C. Testing showed contact impedance below 15mΩ and a 15% reduction in power consumption.
Results
After the network went live, data loss rate decreased by 20%, and battery life improved by 18%. The company reported that the through-hole design accelerated integration and saved 15% of installation time. This case study demonstrates the performance improvements our products bring to the IoT industry, helping customers achieve more reliable smart networks.

Advantages
- Complete product range, full pitch series
- Good materials, all materials meet RoHS, REACH certification
- Both small and large orders are acceptable
- Fast delivery time of average 4 weeks
