Compact. Industrial. Ethernet-Ready.

Enable reliable Ethernet networking in your embedded systems, drones, and robotics platforms with this purpose-built JST GH to TJ-45 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 sacrificing signal integrity or build quality.

Key Features

Connector Format:

• 1 × JST GH 4-pin (1.25mm pitch)

• 1 × TJ-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

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: TJ-45 (RJ45-compatible)

• 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
