GLOSSARY
Glossary of Terminology
Amp / Ampere -
Measurement increment of electric current. Abbreviated as “I”.
Applicator -
A semi-automatic termination machine consisting of an upper and lower half that is used to crimp
contacts onto wire. Used in conjunction with an electrical / mechanical press.
AWG -
American Wire Gauge. A standard system for designating wire diameters.
Blindmate -
To join two connector halves in a normal engaging mode without visual orientation.
Busbar -
Three dimensional constructions enabling electrical distribution of current in power electronic
modules. Typically constructed of copper, busbars are most frequently used in power dense applications
where the busbar offers a cost or space savings over wire.
Color Coding -
A system of identification for terminals housings; and related devices.
Contact Resistance -
The electrical resistance of metallic surfaces at their interface in the contact area under
specified conditions when carrying a specified test current.
Contact Retention -
Minimum axial load in either direction which a contact must withstand while remaining
firmly fixed in its normal position within a housing.
Crimp Retention -
The axial load which a contact can withstand without separation from the wire.
Crimp Termination -
A connection in which a metal sleeve is secured to a conductor by mechanically deforming the
sleeve with presses or automated crimping machines, eliminating the need for solder. Not suitable for solid
(non-stranded wires).
CSA -
Canadian Standards Association, a safety standard writing and testing organization, providing service to
Canada, US, Europe and worldwide.
Cycle Controlled -
To determine if repetitive on or off conditions result in degrading the contact system which may
lead to failures such as “thermal run away”.
Detent -
A bump or raised section projecting from the surface of a contact for keeping the contact in position
relative to another and released by greater force.
Dielectric Strength (Withstanding Voltage) -
The highest potential difference (voltage) that an insulation material
of given thickness can withstand for a specified time without occurrence of electrical breakdown through its bulk.
Finger Proof -
A connector intended for usage external to the end equipment shall have live parts protected
against exposure to contact by persons when assembled, installed, and mated as intended, as determined by
UL Articulated Probe.
Flammability -
The measure of a material’s ability to support combustion. Often tested per UL94.
Flat Wiping -
The sliding action which occurs when contacts are mated. Wiping has the effect of removing small
amounts of contamination from the contact surfaces, thus establishing better conductivity.
Genderless -
A connector in which both mating members are exactly alike at their mating face. There are no
male or female members, but designs provide correct polarity.

GLOSSARY
Heat Rise -
Temperature rise associated with the electrical load applied to a mated connection.
Hermaphroditic (Genderless) Connector -
A connector in which both mating members are exactly alike at
their mating face. There are no male or female members, but designs provide correct polarity.
Hot Plug / Hot Swap -
Live connector insertion / extractions.
IEC -
International Electrotechnical Commission, a standard writing organization that prepares and publishes
international standards for all electrical, electronic related technologies.
Insulation Resistance -
Ratio of applied voltage to the total current between the two electrodes in contact with
a specific insulation.
IP -
Ingress Protection, a standard per IEC 60529 for measurement of ingress for solids and liquids into an enclosure.
Locator / Positioner -
Device for positioning contacts into crimping dies.
Make-First / Break-Last (Premate) -
Sequencing of contact(s) so that they engage prior to the main power
contacts. Typically used for ground / positive earth / neutral positions as a protective measure against excess
currents, short-circuits, and ground faults.
Make-Last / Break-First (Postmate) -
Sequencing of contact(s) so that they engage after the main power
contacts. Typically used for signal or auxiliary power positions to ensure communications are not started or
power circuits switched on until the power contacts are fully engaged.
Mating Force -
Force required to join two connector halves in a normal engaging mode.
Modular -
Refers to similar parts or modules used as building blocks. A modular connector is one in which similar or
identical sections can be assembled together to provide the appropriate connector type or size for the application.
Ohms -
Measurement increment of resistance.
Operating Temperature Range -
Connector temperature rating established by materials used, plastic, finish, and
the base metal. Applying an electrical load will result in a temperature rise that is additive to the operating ambient.
PCB -
Acronym for Printed Circuit Board.
Polarization -
A technique of eliminating symmetry so that parts may only be mated one way.
Pulse (Surge) Current -
Highest instantaneous current that will run.
REACH -
The European Community Regulation on chemicals and their safe use. It deals with the Registration,
Evaluation, Authorization and Restriction of Chemical substances.
Reducing Bushing -
Separate tubular sleeve used to downsize the diameter of a crimp barrel to accept a smaller size wire.
Reeled Contacts -
Contacts attached to a feeder strip for use in a high volume crimping tool.
Resistance -
The opposition to the passage of an electric current through that element. Abbreviated as “R”.
RoHS -
Restriction of Hazardous Substances Directive. The European directive on the restriction of the use of
certain hazardous substances in electrical and electronic equipment.

GLOSSARY
Sacrificial Tip -
An area of a contact system that absorbs electric arching to limit damage to the actual mating
surface of the contacts.
Self-Wiping -
The sliding action which occurs when contacts are mated. Wiping has the effect of removing small
amounts of contamination from the contact surfaces, establishing better conductivity.
Spring Loaded -
A means of providing contact normal force with the use of a mechanical spring.
Storage Battery -
A voltaic battery consisting of two or more storage cells. Energy is accumulated by chemical
activity in the charging process and released on demand in the form of electric current.
Strain Relief -
A means of termination or installation that reduces the transfer of mechanical stress from the conductor.
Termination -
Means of joining contacts to a conductor.
Touch Safe -
A connector intended for usage external to the end equipment shall have live parts protected
against exposure to contact by persons when assembled, installed, and mated as intended, as determined by
UL Articulated Probe.
Turret / Positioner -
Device for positioning contacts into crimping dies.
TUV -
The TÜV Rheinland Group is provider of technical services that certifies products to standards written by
other organizations.
UL -
Underwriters Laboratory, a global safety standard writing and testing organization.
