Glossary of Terms
Insulator — The insulating element into which the
contacts are mounted in a connector. This can be a
resilient material, thermoplastic, or a thermoset
compound, among other materials.
Insulator Rotation — A method of differentiating a
circular connector if more than one connector with
the same sex and layout is to be used in a system.
The insulator is permanently positioned in the shell
so that only a connector with the same degree of
rotation can be mated with it. Possible rotations are
specific to each layout with some layouts having
many possible rotations and others having none. A
chart of valid rotations is listed by layout for
connectors capable of being rotated. Most
connector series use the military convention of
assigning letter designations for specific degrees
of rotation (for example: W, X, Y, Z). See KEYING.
Interchangeable — The characteristic of
connectors in which a connector half of one
manufacturer or series will directly replace that of
another manufacturer and provide the same
electrical and mechanical function.
Intermateable — The characteristic of connectors
in which a connector half of one manufacturer or
series will mate directly with the connector half of
another manufacturer.
Intermittent — Occurring at intervals. A
connection which passes electrical current only in
random or undesirable intervals.
Intermountable
connectors
connector or series will mount in exactly the same
panel space and mounting holes as another
manufacturer’s product.
ISO — Abbreviation for the International Standards
Organization. A group that operates at the
international level and sets most standards for
industry, with the exception of electrical
engineering and telecommunications which are set
by the IEC and ITU respectively. CEN is the
equivalent organization at the European level.
Jacket — The outermost layer of insulation in a
cable composed of several wires.
Jackscrew — A screw attached to one half of a
connector pair used to mechanically align, draw
them together, and lock them in place.
Key — A mechanism used to polarize connectors
by the user. See KEYING.

Keying — A method of differentiating a connector
if more than one connector with the same sex and
layout is to be used in a system. The key is usually
a pin or other projection which can be located in a
contact cavity or slot. The key will prevent a
connector without a matching orifice from mating.
Keying and POLARIZATION serve the same
function, but keying can be done by the user, while
polarization is manufactured into the connector
and normally can not be altered by the user.
Layout — The number, size, and geometric
arrangement of the contacts in a connector. When
a connector is said to have a certain ‘‘layout’’ it
refers to a specific contact configuration. For
example, Combo D has 2 pages of drawings
showing the arrangement of the contacts in the
insulator.
arrangements can be referred to as a layout.
Locator — A part of a crimping tool TURRET.
Rotation of the locator sets the tool for a particular
size or sex contact. See TURRET.
Male Contact — See PIN CONTACT.
Mating Life — The minimum number of times a
connector can be mated and unmated and still
meet all of its design specifications. The maximum
life may be much higher than this figure.
Mil — One thousandth of an inch (.001). Used in
the United States as a unit of length in wire
diameters and linear dimensions.
Mil-Spec
Specification.
Milliampere — One one-thousandth (.001) of an
ampere. Abbreviated mA.
Millimeter — Metric unit of linear measure.
1 millimeter = .03937 inches. Abbreviated mm.
Milliohm — One one-thousandth (.001) of an
ohm. Abbreviated m .
mm
diameters used in Europe instead of AWG. As
numbers get larger, wire diameters increase in
size. The relationship between mm
reverse logarithmic. 1 mm
conversion graph is needed to make accurate
comparisons between AWG and mm
assistance.
Mounting Clip — Any of a variety of mounting
accessories used to secure a connector or
connector pair to a rigid surface.
Multi-Conductor Cable — Two or more individual
wires surrounded by a jacketing material.

Nest — The portion of a crimping die that supports
the contact barrel during crimping.
Newton — A unit of acceleration. One Newton is
the force capable of accelerating 1 kilogram to one
meter per second per second. 1 pound force =
4.448221 Newtons. Abbreviated N.
Ohm — The unit of electrical resistance. One ohm
is the value of resistance through which a potential
difference of one volt will maintain a current of one
ampere. Its symbol is the Greek letter omega ( ).
Operating Temperature — The range of
AMBIENT TEMPERATURES over which the
connector can operate and still meet all of its
design specifications.
Operating Voltage — The range of voltages over
which the connector can be operated. Safety
precautions must be taken anytime a voltage in
excess of 50V is to be used in a circuit. Check your
local and national codes for guidelines.
Outgassing — The circumstance in which an
insulator releases gasses trapped within it under a
vacuum or conditions of decreased pressure, high
heat, or both.
Panel — The outside surface of a piece of
equipment on to which connectors are mounted.
The panel is usually made of metal.
Panel Mount — A connector designed to be
mounted on a panel by means of screws or jam
nut.
PCB — Abbreviation for Printed Circuit Boards.
Performance Class 1 — Performance class per
European specification DIN 41652, specifying
contact performance to 500 mating cycles,
followed by testing per DIN 41640, Part 21. The
contact is subjected to severe environmental
conditions, including industrial gasses, after the
500 mating cycles, and must meet basic contact
resistance, engaging force, and separation force
tests.
Performance Class 2 — Performance class per
European specification DIN 41652, specifying
contact performance to 200 mating cycles,
followed by testing per DIN 41640, Part 21. The
contact is subjected to severe environmental
conditions, including industrial gasses, after the
200 mating cycles, and must meet basic contact
resistance, engaging force, and separation force
tests.
