General Description
Make connections quickly and reliably with this breakout board, which brings every pin of its 50-pin Centronics connector 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.
This breakout board is perfect for production applications as well as experimentation and prototype work. It is well-suited for interfacing with data acquisition equipment, phone systems, or any other devices that use the RJ-21 50-pin Centronics connector.
Centronics connectors are also referred to as a CHAMP or Amphenol connectors. The 50-Pin Centronics is sometimes called a 50-pin telco or RJ-21 connector.
A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".

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.BRKDC50F-R-DIN
