General Description

Centronics, MDR, VHDCI, HPDSUB  Connector Guide
This breakout board contains a 50-pin Mini D Ribbon (MDR) Female connector. Each of the 50 connector pins is brought out to screw terminal blocks, allowing connections to be made easily. Each pin is also brought to solder pads (2 per pin) at 0.1" spacing, allowing easy addition of 0.1" 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.

The connector used on this product goes by several different names, including Mini D Ribbon, Mini Delta Ribbon, MDR, Mini Centronics, Half-Pitch Centronics, HPCN, HPCN50, Half-Pitch CN, and Micro Centronics. It is also occasionally referred to as a SCSI2 connector, though that is not typically a proper use of the term.


These break out boards are perfect for experimentation and prototype work, as well as for use in permanent installations. They are well-suited for interfacing with data acquisition equipment or any other devices that use a Mini D Ribbon connector. 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.

Applications

This breakout board is general-purpose in nature and useful when interfacing to a variety of equipment. The servo drive / servo controller market often uses the 50-pin MDR connector to interface to other equipment. This breakout board is designed to work with this type of system to split out I/O signals for connection to other equipment. Servo equipment with the 50-pin MDR connector includes, but is not limited to, the following:

  • Mitsubishi MELSERVO (MR family -- MR-J3, etc)
  • Yaskawa MP940, MP3200, MP Series, MPiec series, and others
  • Panasonic MINAS series
  • and others...

Some equipment vendors offer breakout modules and cables to accommodate convenient wiring for their equipment. Others offer a cable with a 50-pin MDR connector on one end and wire pigtails on the other end. (One such example is the Mitsubishi MR-J3CCN1CBL cable.) Winford Engineering's MDR breakout boards are intended as an alternative option, terminating the equipment I/O pins on a convenient, compact breakout board.
