Datamate Power & Coax Connectors

4.00mm Pitch High-Reliability Connectors

Harwin’s Datamate (M80 series) connectors provide an extremely flexible interconnect solution, ideally suited for a wide variety of testing environments and conditions. Connectors are available in single row and a wide choice of power or coax contacts. Vibration and shock resistant, ultimately flexible.

About Power & Coax

  • Multiple power level contacts – from 5A up to 40A per contact
  • Coax contacts capable of 6GHz / 50Ohm
  • Housings in 4mm pitch, single row layout
  • Proven contact designs to maintain electrical contact through high vibration and shock
  • Beryllium Copper contacts for improved temperature range: -55°C to +125°C (testing in progress to confirm higher)
  • 500 Mating cycles durability
  • World-class quality from the Original Designers of Datamate – published test reports and proven track record
  • Popular products available from stock, stock availability visible online

Heart of the Connector

The compact design of the housings, the global availability of a product range stocked in depth, the established high-reliability of a COTS connector system. Datamate has become the connector range of choice in many demanding applications on land, sea and air.

With the wide choices of power or coax contacts within the one connector, Datamate Power & Datamate Coax brings true flexibility and space-saving capabilities to this high-reliability connector system.

5 to 20A power contact design, 40A power contact design and inner contact of coax contact

Datamate is a focus product for Harwin, and is undergoing an active development program. The Cable Assembly Service is available for this range as a value-added service – contact us for more information.

Product Styles

All-power or all-coax multiport ganged connectors available with 6GHz / 50Ohm coax contacts, 20A power contacts or 40A power contacts.

  • Wide choice of Jackscrew fixings – none fitted, standard gender (floating jackscrew is on female connector), reverse fix (floating jackscrew is on male connector), guide pins, panel or board mount, and Datamate 101Lok (quarter-turn bayonet fixings for fast mating and unmating).
  • Male connectors in vertical or horizontal orientation on the PCB, or cable connection. Female connectors in vertical orientation on the PCB, or cable connection.
  • Stocked designs include connector-only combinations with female cable and male PCB styles, or additional cabled female connectors in single and double-ended styles. For standard items included in the Datamate Mix-Tek range, please consult the Datamate section of the catalog.
  • Cable size for power contacts will dictate the possible current handling. The connection area for the 20A contact design remains the same, but Harwin recommend choosing the 12AWG contact to achieve this current/power. Contacts for smaller wires are rated for lower currents due to the wire size: 14AWG for 15A, 16AWG for 10A, 18AWG for 8A and 20AWG for 5A.

For signal contacts only, see Datamate. For mixed signal with power or coax contacts, see Datamate Mix-Tek.
