Datamate Connectors

2.00mm & 4.00mm Pitch High-Reliability Connectors

Harwin’s Datamate (M80 and M83 series) connectors provide an extremely flexible interconnect solution, ideally suited for a wide variety of testing environments and conditions. Connectors are available in single, double and triple row configurations. Vibration and shock resistant, ultimately flexible with power/coax options.

About Datamate

  • 3A per signal contact (all electrically loaded; 3.3A per individual contact) at 2mm pitch
  • Proven 4-finger contact design to maintain electrical contact through high vibration and shock
  • Beryllium Copper contact for improved temperature range: -55°C to +125°C (testing in progress to confirm higher)
  • 500 Mating cycles durability
  • Mixed Technology options – Up to 40A per power contact, 6GHz / 50Ohm coax contacts on 4mm pitch
  • World-class quality from the Original Designers of Datamate – published test reports and proven track record
  • Many popular products available from stock – 20-day leadtimes on extended ranges. Stock availability visible online.

Heart of the Connector

The compact design of a 2mm pitch connector (for signal), 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.

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

Product Styles

  • Datamate J-Tek – The ultimate security and strain-relief, a variety of connector systems with a choice of slotted or hex socket jackscrew fixings, with board-mount for PCB connectors and panel mount for cable connectors. Polarized, with #1 contact marked. Includes Datamate 101Lok (quarter-turn bayonet fixings for fast mating and unmating), Datamate T-Contact (up to 8.5A power contacts for 2mm pitch) and Datamate 3-Row (triple row connectors also known as the M83 series).
  • Datamate Mix-Tek – 4mm pitch single-row 20A/40A power contacts or 6GHz, 50Ohm coax contacts mixed with 2mm pitch double-row signal contacts, based on the Datamate J-Tek housing design. Includes Datamate Power and Datamate Coax, connectors without any signal contacts.
  • Datamate L-Tek – The original 2mm pitch connector system. Designed and Developed by Harwin, we are the only manufacturer supplying to British Standard 9525-F0033.
