Scattering Parameters (S-Parameter), S11, S12, S21, S22
S11 is the reflection coefficient at the input port of the device under test, defined as the ratio of the reflected voltage to incident voltage. S12 is the reverse transmission coefficient (isolation), The 12 is derived from the signal appearing on the input port ( port 1) from signal applied to the output port (port 2). S21 is the forward transmission coefficient (gain), S21 are signals on the output (port 2) of the device under test, resulting from signals applied to the input (port 1). S22 is the output reflection coefficient as defined by the ratio of the incident voltage to the reflected voltage. The above S-parameters are for single ended systems. S-parameters are frequency dependent, and are by default normalized to 50 ohms. There are additional parameters for differential systems.

A connector designed to prevent the radiation of electromagnetic interference to and from the internal conductor(s).

A socket contact that is simply a conductive tube. Sleeves do not contain pin grips or any other amendments and are usually used with split pins.
Slotted Tongue Terminal
A terminal, having a bifurcated tongue, that allows attachment to a screw or stud without removal of the mounting hardware.
Used to describe the easy removal or assembly of one part to another. Example: certain connectors are provided with snap on plastic covers to permit quick and convenient installation.

A connector intended to mate with a plug in device such as tubes, relays, transistors, microcircuits, etc.
Socket Contact Sleeve
A sleeve that holds the contact spring in the correct position within the socket contact.
Socket or Receptacle Contact
A contact designed to interconnect with a pin contact, generally, by capturing or surrounding it.
An alloy that melts at relatively low temperatures, and that is used to join or seal metals with higher melting points.
The cup or well at the end of a contact or terminal into which a wire is inserted prior to being soldered.
A solder type contact provided with a hole at its end through which a wire can be inserted prior to being soldered.
A substance that transforms a passive, contaminated metal surface into an active, clean, solderable surface.
A heat shrinkable tubing device containing a predetermined amount of solder and flux used for environmental resistant solder connections and shield termination.
Solder Type Connector
A connector in which the contact between the conductor and the connector is made by a solder joint.
The joining of two materials by pressure means without the use of solder, brazing or any method requiring heat.
A contact with a termination portion that is a hollow cylinder to allow it to accept a wire. After a bared wire is inserted, a swaging tool is applied to crimp the contact metal firmly against the wire. Usually called a crimp contact.
A technique of connecting uninsulated solid wire or stripped insulated wire to a terminal post containing a series of sharp edges, by winding the wire around the terminal. (see WIRE-WRAP)
Specimen Environment Impedance
The impedance presented to the signal conductors of the device under test by the test fixture. This impedance is a result of transmission lines, termination resistors, attached receivers or signal sources, and fixture parasitics.
Spring Finger Action
Design of a contact as used in a printed circuit connector or socket contact, permitting easy stress free spring action to provide contact pressure and/or retention.
Staggered Contact Connector
A connector having a staggered arrangement of the terminations and/or the contacts.
A contact for individual mounting to a printed board by staking, and normally soldered to a land.

The voltage difference between the 0% and 100% levels, ignoring overshoot and undershoot.
An internal keying-type device incorporated into plugs and receptacles allowing the connector to be mated only one way. The connector is rotated until the step-planes match; then it is pushed together.
A method of mounting a connector or other electrical element to a circuit board or other similar member such that the connector contact elements can be attached to both opposing surfaces of the circuit board, with the connector mounting means straddling both sides and the edge of the circuit board.
A technique involving devices or methods of termination or installation, that reduce the transmission of mechanical stress to the conductor termination.
Strain Relief Clamp
A clamp designed to remove the strain of a cable pulling on the connector’s contacts. Strain reliefs may be attached to the connector or may be part of a cable support system.
