DIN Connectors

This connector is typically used on hydraulic valves. Follow
manufacturer installation instructions.

Exclusions

A limited number of connectors do not benefit from dielectric
grease, or may be permanently damaged by application.
Dielectric grease may not be required in properly sealed
enclosures.

Brad Harrison/phoenix Contact M12

The connector uses gold contact material to resist corrosion
and an o-ring seal for moisture integrity. If dielectric grease is
mistakenly applied to this connector system, the low-force
contacts cannot displace the grease to achieve electrical con-
tact. Once contaminated, there is no practical way to remove
the dielectric grease (replacement of female contacts
required).

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).
