InLine Adapter DB9 female / RJ45 8P8C female metal-coated housing 68889L

The InLine Adapter DB9 female / RJ45 8P8C female (metal-coated housing) provides a DB9F to RJ45 8P8C female connection in a durable, metal-coated plastic case. Pins for the SubD (DB9) plug are not fixed and can be assigned freely, allowing custom pin mapping for serial-to-network or crossover applications. The adapter is grey and intended for reliable data transmission between serial devices and network equipment.

Advantages

The metal-coated housing increases mechanical durability and provides better shielding compared with plain plastic enclosures. The DB9 female and RJ45 8P8C female connectors offer standard interfaces for serial and Ethernet-style cabling. Flexible pin assignment on the DB9 side allows use in different wiring schemes and simplifies integration with existing equipment.

Suitable for

• Connecting RS-232 serial devices to RJ45-wired network panels or adapters
• Custom serial pin mapping and conversions
• Laboratory, testing, and repair benches requiring flexible connector assignment
• Legacy equipment integration with RJ45-based patching systems

How to use

Insert the DB9 male plug of the device into the DB9 female side of the adapter and connect an RJ45 cable to the RJ45 8P8C female port. Ensure the wiring scheme matches the intended signal mapping because DB9 pins are not fixed; verify pin assignments before applying power or signals. Use standard fastening or mounting practices to secure the adapter and connected cables.

Recommendations

Verify the required pinout for your serial device and the receiving equipment before connecting. Avoid applying voltages outside the specifications of the connected devices. For improved EMI protection, use shielded RJ45 cables and ensure proper grounding where applicable.
