Datamate

A 2.00mm pitch high-reliability connector range designed and manufactured by Harwin, low-profile and compact, available in 1, 2 or 3 row formats. Available in Board-to-Board, Cable-to-Board and Cable-to-Cable configurations. Options include with latches or with jackscrews. See also Datamate J-Tek, Datamate Mix-Tek, Datamate Power, Datamate Coax and Datamate L-Tek, and our blogpost on "What is Datamate?".

Datamate Coax

A 4.00mm pitch high-reliability connector range designed and manufactured by Harwin. This sub-range of the Datamate family is based on the Datamate Mix-Tek connector system, but uses simply coax contacts in a single row format. Jackscrews are located at either end of the connector housings. See also our blogpost on "What is Datamate?".

Datamate J-Tek

A 2.00mm pitch high-reliability connector range designed and manufactured by Harwin. This sub-range of the Datamate family is in double or triple row formats, with jackscrews located at either end of the connector housings. Available in Board-to-Board, Cable-to-Board and Cable-to-Cable configurations. See also our blogpost on "What is Datamate?".

Datamate L-Tek

A 2.00mm pitch high-reliability connector range designed and manufactured by Harwin. This sub-range of the Datamate family is in single or double row formats, with Beryllium Copper latches located at either end of the connector housings. Available in Board-to-Board, Cable-to-Board and Cable-to-Cable configurations. See also our blogpost on "What is Datamate?".

Datamate Mix-Tek

A 2.00mm pitch high-reliability connector range designed and manufactured by Harwin. This sub-range of the Datamate family is based on the double row format of Datamate J-Tek, with jackscrews located at either end of the connector housings. The contacts are a mixture of signal (in double row) and power or coax (or both) in single row - each special contact (power or coax) takes up the same space as 4 signal contacts. Available off-the-shelf in Cable-to-Board format, with Board-to-Board and Cable-to-Cable configurations available made-to-order. See also our blogpost on "What is Datamate?".

Datamate Power

A 4.00mm pitch high-reliability connector range designed and manufactured by Harwin. This sub-range of the Datamate family is based on the Datamate Mix-Tek connector system, but uses simply power contacts (either 20A max or 40A max) in a single row format. Jackscrews are located at either end of the connector housings. See also our blogpost on "What is Datamate?".

Datasheet

A document with some technical content that normally shows the physical dimensions of a product, and may also include specification information, usage information, general product data, etc. There is no set standard that defines the contents of a datasheet, and this will vary across manufacturers. Harwin use the Technical Drawing as the Datasheet, as we include all the relevant dimensions, and a summary of the specification. Datasheets are available from individual product pages.

Digital signal

A discrete signal for which both time and amplitude have discrete, defined values. Any drift from these values (such as from interference/noise) can be detected and corrected. This is in comparison to analog signals, where interference or noise are difficult to detect and remove.

Direct Current (DC)

An electric current whose electrons flow in only one direction.

Discontinuity

A broken (temporary or permanent) connection, such that current is interrupted and unable to flow at that point. Used as a pass criteria for various physical tests (such as vibration).

Dodd-Frank

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2009 introduced changes to the yearly financial reporting that certain USA companies submit to the SEC (Securities Exchange Commission). The changes included a requirement (Section 1502) to declare on whether their products were conflict-free, i.e. did not use any of the four Conflict Minerals (Tin, Tantalum, Tungsten and Gold) from a conflict source.
