General Description

Make connections quickly and reliably with this breakout board, which brings every pin of its 8P8C / RJ45 modular jack connectors out to screw terminals.

Each pin, including shield, is also brought to solder pads (3 per pin) at 0.1" spacing, allowing easy addition of pin headers or other components. 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 two 8P8C modular jack connectors 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 connector(s). 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.).

The connector shield is connected to a copper plane on the PCB (to minimize electrical noise) in addition to being brought out to a screw terminal.

This breakout board is perfect for production applications as well as experimentation and prototype work. It is well-suited for work with serial ports, sensors, data acquisition equipment, RS-232 devices, MODBUS connections, and other devices that use RJ45/8P8C connectors.

The '8P8C' designation on the modular jack stands for '8-Position, 8-Conductor', which is compatible with RJ45 connectors.

A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", 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.
