There are 22 names in this directory beginning with the letter H.
HARDWARE
Hardware usually means shells, guide pins, polarizing pins, strain relief clamps, mounting screws, etc.

HARNESS
A group of wires or cables routed together with or without attached components and secured in a manner to provide a preshaped electrical wire or cable assembly.

HEAD ASSEMBLY
A positioner designed to attach to a crimping tool in place of a turret head.

HEADER
A header is a feedthrough device that introduces a conductive path(s) through a panel or other planar surface.

HEAT DISTORTION
The deformation of a material due to the application of heat.

HEAT ENDURANCE
The time of heat exposure a material can withstand before failing a specific physical test. Heat endurance is an important consideration during oven or vapor phase soldering of terminations.

HEAT SOAK
Heating a circuit over a period of time to allow all parts of the package and circuit to stabilize at the same temperature.

HERMAPHRODITIC CONNECTOR
A connector in which both mating members are exactly alike at their mating face. There are no male or female members.

HERMAPHRODITIC CONTACT
A contact design that is neither pin nor socket and which mates with other contacts of the same design. E.g., "tuning fork", brush contact, butt contact, etc.

HERMETIC CONNECTOR
A connector that has its contacts bonded in place, usually with fused glass, that permits a pressure differential to be placed across the connector without it leaking or bypassing.

HERMETIC SEAL
Hermetically sealed connectors are usually multiple contact connectors where the contacts are bonded to the connector by fused glass or other material and permit a maximum leakage rate of 1.0 micron ft. per hour.

HERTZIAN
Calculation of weight distributed over a cross sectional area (point of contact) in ksi or MPa.

HERTZIAN STRESS
Stress expressed in pounds per square inch, or equivalent, that is developed during the elastic deformation phase of establishing contact. The stress is a result of normal force and the geometry of the contact and the modulus of elasticity of the contact material.

HIGH ORDER MODE
A propagation path that makes a relatively large angle with respect to the fiber axis.

HOLDING STRENGTH
Ability of a connector to remain assembled to a cable when under tension.

HOOD
A shroud or enclosure attached to and surrounding a connector.

HOOK TONGUE TERMINAL
A terminal with a hook shaped tongue.

HOOP STRESS (wire wrap)
The tension in the wire induced by the wrapping operation and maintained by the wire being locked on the corners of the post.

HOT-LINE CLAMP
A connector that may be installed or removed by means of an insulated stick while the conductor is energized. Also called Live-Line Connector.

HOUSING SEAL
A seal provided between the housings to prevent the ingress of moisture and contaminants into the interior of connectors when mated.

HOUSING, ELECTRICAL CONNECTOR
The portion of a connector into which the insert is assembled. Also called "shell."

HYGROSCOPIC
Capable of absorbing moisture from the air.
