General Description

These slim profile breakout boards bring all 37 pins plus shield of a DB37 connector out to screw terminal blocks, allowing simple and quick connections for prototypes or permanent installations. These breakout boards are perfect for field wiring tasks and are available in two different connector hardware options: captive screws or jack screws. The jack screws work well when mounting the breakout board to a wall box plate or thin panel that has a DB37 cutout; the captive screws provide a convenient connection to a mating connector that already has jack screws. See the Connector Hardware Options section below for more details.

The small footprint means that the end profile of the breakout board is no wider than the connector itself. This can be important for installations where equipment contains multiple connectors which are spaced closely together. Even in these tight spaces, these slim breakout boards can stillbe mounted directly to the equipment without the use of extension cables.Although the breakout board footprint is small, provision for strain reliefs has been included; holes drilled in the board provide anchor points where tie-wraps can be attached.

These breakout boards are available with both male and female connectors. The BRKSD37M has a male connector, and the BRKSD37F has a female connector. For larger DB37 breakout boards that include a prototyping area, mounting holes, and DIN rail mounting options, please click here.

These break out boards are perfect for experimentation and prototype work,as well as for use in the educational laboratory. They are well-suited for work with RS-232 serial ports, I/O cards, automation controls, and any other device that uses a DB-37 connector. A breakout board is sometimes referred to as a "transition module", "terminal board", or "interface module".

Connector Hardware Options

These breakout boards are available with either captive screws or jack screws for the connector hardware:
Captive Screw Jack Screw
Captive Screw Jack Screw
  • Captive Screws are male #4-40 screws coming out of the face of the connector to accommodate direct mounting to a mating connector which contains jack screws (see picture below).
  • Jack Screws are the hex standoffs typically installed on DSUB connectors; they are threaded for #4-40 screws. Jack screws are perfect for connecting to a cable which has thumbscrews, for mounting to a wall plate, or for installing on a thin panel which has a DB37 cutout (see picture below).
