MIL-C-5015 SPEC CONNECTOR'S
Crown Connector Inc's recommendation is to not use
dielectric grease for this series connector. For similar
model series connectors, the manufacturer should be
contacted for confirmation before applying dielectric
grease. A typical application for this connector is on
David Clark Intercom connections in Aerial Work Plat-
forms.
MOLEX CMC SERIES CONNECTORS
The CMC connector family is a sealed, high-density con-
nection system using matte-seal technology for CP
0.635 and 1.50 mm terminals. To guarantee IP6K7 and
IP6K9 sealing, a seal plug option is used. However, the
low-force contacts cannot displace dielectric grease and
create electrical contact. It is possible to use solvents
(i.e. contact cleaner or mineral spirits) for the removal of
improperly applied dielectric grease. The flexbox con-
trol modules from JDES employ this connector system
(for example).

AMP CONNECTOR
Applying Silicone Dielectric Compound to AMP
Connectors
Silicone Dielectric Compound must be used on the AMP con-
nections for the following reasons:
• To prevent oxidation at the mechanical joint between male
and female pins.
• To prevent electrical malfunction caused by low level con-
ductivity between pins when wet.
Use the following procedure to apply Silicone Dielectric Com-
pound to the electrical connectors.
1. To prevent oxidation and low level conductivity, silicone
dielectric grease must be packed completely around
male and female pins on the inside of the connector
after the mating of the housing to the header. This is
easily achieved by using a syringe to fill the header with
silicone dielectric compound, to a point just above the
top of the male pins inside the header. When assem-
bling the housing to the header, it is possible that the
housing will become air locked, thus preventing the
housing latch from engaging.
2. Pierce one of the unused wire seals to allow the trapped
air inside the housing to escape.
3. Install a hole plug into this and/or any unused wire seal
that has silicone dielectric compound escaping from it.
