ITT RMDB1

Micro-D Plastic Shell - .050" Contact Spacing
Microminiature Rectangular Connectors
with MICRO-Pin Contacts on .050 (1.27)
centers.
MICRO-D microminiature rack/panel connectors are used in applications requiring highly
reliable, extremely small, lightweight connectors. These connectors are available in 2 insulator materials, 2 mounting variations, 7 shell
sizes accommodating from 9 to 51 contacts
and a special arrangement of 5 micro contacts
and 2 coaxials. The insulator materials listed
give the MICRO-D connector wide versatility
in most applications required by industry.
MD**
ITT can also terminate a wide variety of
stranded or solid wire directly to MICRO-D
contacts, which is often desirable in high density arrangements.
• Glass-filled diallyl phthalate thermoset
material used in high temperature applications that is immune to cleaning solvents.
It also has excellent dielectric properties.
Temperature range: -65˚F to +300˚F
(-55˚C to +149˚C).
MICRO-D connectors can also be custom harnessed to meet any customer requirement of
single or multiple connectors. Pigtail lead and
harness description must be given by the customer. A typical description would be: .5" #25
AWG, gold plated copper leads or 18" of #26
yellow, Teflon-insulated, Type E wire. Shown
below are various methods of termination.
Consult customer service for any routine or
complex harnessing of MICRO-D connectors.
• Glass-filled polyester thermoplastic that is
not affected by cleaning solvents and
exhibits excellent dielectric properties.
Temperature range: -55˚F to +257˚F
(-65˚C to +125˚C).

Micro-D Plastic Shell - .050" Contact Spacing
MD*B-PCB connectors use standard MD*B all
plastic shells and are designed for use with
flex circuitry, printed circuit and multi-layer
boards. They are easily mounted and soldered
and provide high density/high reliability in
board-to-board and board-to-cable applications. While being similar to the MDM-PCB
connectors, the MD*B-PCB connectors are all
plastic, extremely small, and lightweight yet
rugged enough for use in the most demanding
applications.
MD*B-PCB
Jackpost mounting for use with locking hardware is also available.
If the connectors shown in the catalog do
not meet the requirements of your applications, a special shape, size or layout using
the basic all plastic shell can be made available. For further technical and applications
information, contact customer service.
MD*B-PCB connectors are available in
seven shell sizes with 9 to 51 contacts in the
popular 90° narrow profile PCB termination,
with a variety of tail lengths for varying board
thickness.

Panel Mounting Hardware
Clip Mounting
Illustrated is the recommended method of front mounting
with metal panel mounting keys. Panel mounting keys are
available with or without coupling retention clips.
For front mounting, place the rear of the connector thru
the panel cutout. With the mounting flange against the
panel, fully insert the panel mounting keys thru the slots
in the flange and thru the panel cutout. Retaining the
keys in this position, bend them outward against the rear
of the panel. When mating a front mounted connector
with an unmounted connector, a coupling retention clip
assembly may be used to securely lock the two together.
Mounting screw brackets are available and may be used
instead of the panel mounting keys.

Edgeboard Mounting
1. A panel thickness of 1/8" (3.17mm) maximum is recommended for ease of tab bending
when a panel mounting key & clip assembly or edgeboard mounting brackets are used.
2. Front mounting is preferred. However, when rear mounting is necessary, use figure 3 for
dimensions.
