Engine Control unit connectors
Many times, these types of connectors use back-seals for mois-
ture integrity. 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 EMR4
engine control module from Deutz employs this connector
system (for example).
Sealed Enclosures
Application of dielectric grease is not required in properly
sealed enclosures. To meet criteria, the enclosure must be
rated to at least IP66 (dust tight; protected from powerful jets
of water). The enclosure must be fitted with a high quality,
continuous gasket and all wiring must pass through cable
entrances.
MIL-C-5015 SPEC Connector’s
Crown Connector Inc’s recommendation is to not use dielec-
tric grease for this series connector. For similar model series
connectors, the manufacturer should be contacted for confir-
mation before applying dielectric grease. A typical application
for this connector is on David Clark Intercom connections in
Aerial Work Platforms.
Molex CMC Series Connectors
The CMC connector family is a sealed, high-density connec-
tion system using matte-seal technology for CP 0.635 and
1.50mm terminals. To guarantee IP6K7 and IP6K9 sealing, a
seal plug option is used. However the low-force contacts can-
not 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 control modules from JDES employ this connector sys-
tem (for example).
