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
