General Description

Make connections quickly and reliably with these screwless spring terminal breakout boards, which feature terminals made by Phoenix Contact. These breakout boards bring all 9 pins of a DB9 connector out to spring connection terminal blocks for quick, easy, secure connections. Each connector pin is also brought to solder pads which allow easy access for testing or the addition of soldered components. The solder pads are arranged on standard 0.1" spacing, supporting the addition of standard pitch components such as 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.

These boards are available with either a male connector (BRKG9M) or a female connector (BRKG9F).

Spring Terminal Animation
This breakout board features push-in spring connection terminal blocks. These screwless spring clamp terminal blocks allow connections to be made very quickly and efficiently. The spring terminal connections are reliable and secure, but wires can be connected and disconnected in a fraction of the time required with standard screw terminal blocks. Simply depress the actuator button on top of the terminal block, insert or remove the wire, and release the button. Done! In addition, screwless spring connections can offer better results in environments where vibration could potentially loosen standard screw terminal block connections. If your application requires screw terminals rather than spring terminals, please consider the BRK9 design or the other DB9 options listed here.

This break out board is perfect for production applications as well as experimentation and prototype work. It is well-suited for work with RS-232 serial ports, data acquisition equipment, and any other device that uses a 9-pin DSUB 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", "terminator", or "interface module".

Technically, the correct term for a DB9 connector is DE9, but that term is not commonly used.

Connector Style

These breakout boards are available with either a Right Angle connector or a Straight ("Vertical") connector. The terms Right Angle and Straight refer to the connector itself, NOT the relationship of the mating cable to the plane of the PCB. In fact, the cable mating to a Right Angle connector is parallel to the PCB, while the cable mating to a Straight connector is perpendicular to the PCB. These are pictured below:

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 -N have no mounting hardware included; they can be easily panel-mounted by using 1/4" nylon standoffs under the mounting holes, and #6 screws.
