Harwin's T-Contact products now available worldwide
Following on from the release of its narrow-pitch T-Contact offering last year, Harwin - which produces interconnect solutions for the defence, aerospace and space sectors - has now secured supply chain support from leading distributors Digi-Key, Mouser and TTI.
Intended for incorporation into Harwin’s flagship Datamate series, each T-Contact makes use of an innovative six-finger mechanical design, which has been machined out of a single piece of Beryllium Copper. Consequently, these compact and lightweight female contacts are able to deliver up to 8.5A in a 2mm pitch high-reliability connector – thereby boosting the current carrying performance of the previous generation of Datamate contacts by 250% and setting a new benchmark for the industry as a whole.
In addition to its elevated conductive properties, Beryllium Copper exhibits considerably greater spring performance than conventional connector contact materials (such as brass or phosphor bronze). Consequently, Harwin’s T-Contacts are able to endure 1000 mating cycles. Thanks to their gold plating, they have heightened levels of operational robustness – with a working temperature range of -55°C to +125°C, 100G shock resistance and vibrational resilience of 40G (390m/s²) for six hours. This means that they are suitable for deployment in even the most uncompromising of application environments.
“The longstanding relationships that we have with Digi-Key, Mouser and TTI have been instrumental in the company’s continued growth – enabling us to address key markets all over the world,” said Giorgio Potenza, Strategic Market Manager at Harwin. “Now, through the assistance of these highly-valued distribution partners, and the extensive commercial reach that they command, we can explore opportunities for our improved T-Contact-based Datamate connector portfolio in areas like unmanned vehicles, avionics and satellites.”
Ridhwan Islam, Field Applications Engineer, Harwin added: “The T-Contact presents a unique proposition to engineers. Because of our proprietary one-piece design, the constituent materials can be significantly thicker, thus reducing the overall contact resistance and increasing conductivity, as well as allowing enhanced thermal properties to be benefitted from.”
