General Description
Make connections quickly and reliably with this breakout board, which brings every pin of its 20-pin Mini D Ribbon (MDR) Female connector out to screw terminals. Double-deck screw terminals efficiently utilize board area to provide a compact footprint.
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.
This breakout board is perfect for production applications as well as experimentation and prototype work. It is helpful for working with Data Aquisition (DAQ) equipment, I/O cards, and other devices that use a Mini D Ribbon connector.
We stock several MDR breakout board styles and form factors. Please have a look here.
A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".
MDR Connector Details
The Mini Delta Ribbon (MDR) series of connectors provides a compact arrangement of durable sliding 'ribbon' contacts. The high contact density and good performance at high speeds have yielded many applications for this connector type. These are 'half-pitch' connectors, meaning that the contact spacing is tighter than full-size Centronics connectors, such as those used on our BRKDC36F or BRKDC50F breakout boards. The 'half-pitch' connectors utilize contacts on 0.05" centers.
Winford Engineering currently utilizes MDR connectors from 3M™ on these breakout boards; connector details are listed 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 -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.
