EDGE CONNECTORS-PRINTED CIRCUIT
One-piece - connector that mates directly with PC board by slipping over and gripping the board edge. Connection is made between spring contacts in connector and tabs or contact strips on the PC board. PC board acts as half of the connector. Two-piece - connector plug half is soldered to PC board tabs and becomes permanent part of the board. Plug/board unit is joined to receptacle half to make connection. Side-entry - PC board slides into connector that makes contact with three sides of the board.

EDGEBOARD CONNECTOR
A connector into which the edge of a printed board is inserted to make direct contact to edge-board contacts.

EDGEBOARD CONTACT
A series of contacts printed on or near any edge of a printed board and intended for mating with any edge connector.

EFFECTIVE PRESS-IN LENGTH
The length of contact between the press-in section of a press-in termination and the metal plating of the plated-through hole in a printed board in that the press-in termination is inserted.

EFFECTIVE WRAPPING LENGTH
That portion of a wrap post suitable and available for the application of the wrapped connection.

ELASTOMER
A family of plastics often used in connectors. Any elastic, rubber-like molded plastic such as fluorosilicone or Neoprene that deforms slightly under pressure to act as a seal.

ELECTRICAL CONNECTOR
A mechanical coupling device that can be engaged or disengaged at will and includes one or more electrical contact elements that provides a path or multiple paths for the conduction of electrical current.

ELECTRICAL ENGAGEMENT LENGTH
The distance a contact travels on the surface of its mating contact during engagement or separation.

ELECTROLESS DEPOSITION
The deposition of conductive material from an auto-catalytic plating solution without application of electrical current.

ELECTROMAGNETIC INTERFERENCE (EMI)
Interference from unintentionally radiating electric sources like motors, diathermy equipment, etc.

ELECTROPLATING
The electrodeposition of an adherent metal coating on a conductive object for protection, decoration, or other purposes.

ELECTROTINNING
Electroplating tin on object.

ENCAPSULATING
Enclosing an article in an envelope of plastic or other similar material.

END TAIL
The final portion of the last turn of wire in a wrapped connection that extends beyond the last corner contact.

ENGAGEMENT INDICATORS
Marks that indicate when a connector is fully engaged.

ENVIRONMENTAL CONNECTOR
A connector provided with means for protection against moisture, temperature or contaminants.

ENVIRONMENTAL SEAL
A device that is provided with gaskets, seals, grommets, potting or other means to keep out moisture, dirt, air or dust that might reduce its performance. An environmental seal is not designed to exclude EMI/RFI.

ENVIRONMENTALLY SEALED
The provision or characteristic of a device that enables it to protect against the entry of moisture, fluids, and foreign, particulate contaminants that could otherwise affect the performance of the device.

EXTRACTION TOOL
A device used for removing removable contacts (designed to be reusable/replaceable) from their retaining cavity or mechanism.

EYE PATTERN
An oscilloscope display of synchronized pseudo-random digital data (signal amplitude versus time), showing the superposition of accumulated output waveforms.

EYELET
A terminal or tab that is pierced or a closed hook shape, that provides a good mechanical as well as an electrical connection.
