Crimp contacts
Whereas the contacts for screw, axial screw, tension clamp
and Push In connections are already built in, the customer can
choose the appropriate contact for a crimp connection.
The contacts are the heart of a plug-in connector. They repre-
sent the actual connection between two conductors. Two kinds
of contact are necessary: pins and sockets (male and female).
The pin conducts the electrical current on its outer surface
and is introduced into the socket, which conducts the electrical
current on its inner surface. Heavy-duty connectors have
copper alloy contacts and the contact surfaces are plated with
gold or silver: silver improves conductivity, gold is corrosion-
proof.
Crimp contacts are available in turned, solid form.
Selection of silver or gold-plated contacts
When using plug-in connectors under standard conditions, the
resistance between the contacts has little effect. Even heavily
corroded silver-coated contact pins and sockets rarely show
contact problems.
The situation is different where there are very small currents in
extreme applications such as those in electroplating shops,
tunnels or in cellulose processing. The silver oxide layer on the
surface of the contacts forms an electrical resistance with
capacitive, inductive and ohmic components. As a result, the
original signal is distorted so much that the recipient is unable
to detect it properly and interprets it incorrectly. This results in
faults and, indirectly, to damage to machines and processes.
Gold-plated contacts should be used in such cases.
The rule of thumb is: use gold-coated contacts for currents
< 5 mA and voltages of up to 5 V.
