JST GH 4-Pin to RJ45 Ethernet Adapter – 100Mbit

Compact. Industrial. Ethernet-Ready. Enable reliable Ethernet networking in your embedded systems, drones, and robotics platforms with this purpose-built JST GH to RJ45 adapter. Designed specifically for 100Mbit (100BASE-T) operation, this adapter bridges the gap between compact 4-pin JST GH connectors and standard RJ45-compatible Ethernet interfaces—without compromising signal integrity or mechanical robustness. Key Features Connector Format: 1 × JST GH 4-pin (1.25mm pitch) 1 × RJ-45 (compatible with RJ45 jack) Ethernet Compatibility: Designed for 100Mbit/s (Fast Ethernet) operation Ideal for Ethernet PHYs using differential TX/RX pairs Signal Integrity: Maintains 100-ohm differential impedance Optimized for short-run, high-reliability applications in constrained spaces Form Factor: Minimal footprint—easy to integrate into UAVs, robots, or test rigs Mechanically secure JST GH connection for vibration-prone environments M3 Screw holes on each corner Robotics and Embedded Application Ready Integrate Ethernet into flight controllers, navigation modules, or embedded Linux systems Quick prototyping for development boards with nonstandard Ethernet connectors Replace bulky RJ45 jacks in space- or weight-sensitive projects Technical Specifications Input: 4-pin JST GH Output: RJ-45 Ethernet Standard: IEEE 802.3u (100Base-T) Pin Mapping: Direct differential pair routing (TX+/TX–, RX+/RX–) Cable Support: Works with unshielded or shielded twisted pair (UTP/STP) Use Case Examples Ethernet communication for drones and aerial platforms Custom control interfaces in robotics or AGVs Embedded system networking in lab, field, or industrial setups Connecting development boards to switches or routers in constrained setups If you need a version with a different JST GH pinout or custom cable lengths, contact us—custom configurations available on request
