General Description

This RJ45 breakout board brings all 8 pins plus shield of an 8P8C / RJ45 shielded modular jack out to screw terminal blocks, providing simple and convenient connection to each connector pin. Each pin is also brought to solder pads (3 per line) at 0.1" spacing, allowing the easy addition of standard pin headers. Please note that the breakout boards are manufactured with a connection between each connector pin and the corresponding terminal block position; no soldering of any type is necessary. The solder pads simply provide an area for making optional connections to additional headers or other components.

In addition, this board functions as a buss board, featuring four 8P8C shielded jacks wired in parallel and connected to the solder pads and the screw terminals. This allows the user to easily break out a connection to screw terminals while at the same time connecting other cables to the same signals via the extra jacks. This is very convenient when "daisy-chaining" several devices together or when wiring multiple devices in parallel. Note that all connections are wired 1-to-1 (ie Pin 1 to Pin 1, Pin 2 to Pin 2, etc.).

This break out board is perfect for production wiring, for experimentation and prototype work, and for use in the educational laboratory. It is well-suited for work with RS-232 serial ports, sensors, data acquisition equipment, and any other device that uses an RJ45/8P8C connector. It can be helpful in making MODBUS connections. A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", or "interface module".

Connector Style

These breakout boards utilize Straight ("Vertical") connectors. This term refers to the connector itself, denoting that it rises straight out of the circuit board rather than at a right angle. The cable mating to a Straight connector is perpendicular to the PCB, as one can infer from the product photos.

Mounting Options

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
