RMDB1-21PH1K Overview

Micro-D Plastic Shell - .050 Contact Spacing

Micro-D Plastic Shell - .050" Contact Spacing
Microminiature Rectangular Connectors
with MICRO-Pin Contacts on .050 (1.27)
centers.
MICRO-D microminiature rack/panel connec-
tors are used in applications requiring highly
reliable, extremely small, lightweight connec-
tors. These connectors are available in 2 insu-
lator 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.
ITT can also terminate a wide variety of
stranded or solid wire directly to MICRO-D
contacts, which is often desirable in high den-
sity arrangements.
MICRO-D connectors can also be custom har-
nessed to meet any customer requirement of
single or multiple connectors. Pigtail lead and
harness description must be given by the cus-
tomer. 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 diallyl phthalate thermoset
material used in high temperature applica-
tions that is immune to cleaning solvents.
It also has excellent dielectric properties.
Temperature range: -65˚F to +300˚F
(-55˚C to +149˚C).
• 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).
