Smart Homes
Magnetic & Ethernet Interface Solutions for Smart Home Devices
Smart home ecosystems—ranging from voice assistants to intelligent gateways—rely heavily on compact, energy-efficient, and noise-tolerant Ethernet interfaces. LINK‑PP supports these applications with magnetic RJ45 connectors and LAN magnetics that provide EMI suppression, PoE capability, and seamless integration into embedded systems. Our components are optimized for high integration, compact enclosures, and reliable performance in connected home environments.
Connectivity Requirements in Smart Home Applications
- Compact PCB Footprint — Devices like smart hubs and security panels require low-profile RJ45 and transformers.
- Low Power Consumption — Many devices operate on minimal power budgets; transformer efficiency is critical.
- PoE Integration — Smart hubs and wall-mounted units often rely on Power over Ethernet (PoE/PoE+).
- EMC Compliance — With dense electronics in homes, EMI filtering is essential to meet Class B limits.
