Circuit board connections with har-flex® – robust, flexible and versatile

HARTING’s har-flex® product range provides versatile solutions for circuit board connections in industrial devices. The variants available cover a wide range of “board-to-board” and “board-to-cable” applications in a contact pitch of 1.27 mm.

Featuring a compact but robust design, har-flex® ensures reliable operation at all times – also under adverse conditions. Two large holders ensure the connectors are firmly held in place using SMT joints. A low-wear insertion and withdrawal procedure is ensured by a very smooth contact point between the male and female contacts. This is the result of special follow-up treatment in the punching process which HARTING applies based on its extensive experience with punching technology. This characteristic also has a positive impact on vibration resistance that has been verified according to recognized test standards.

The har-flex® IDC connector for flat ribbon cable also meets the most exacting requirements in terms of robustness. A secure catch prevents unintentional removal of the cable from the circuit board. A tensile relief clamp is available as an option to protect the cable insulation displacement connection from the impact of force. In addition to the individual IDC connectors, HARTING also offers prefabricated cables in individual designs.

The different har-flex® variants can be freely combined and enable modular device configurations. The spatial requirement on the circuit board is minimized thanks to the variable number of contacts from 6 to 100. har-flex® data transmission meets the requirements of modern transmission protocols, such as Gigabit Ethernet and PCI Express. In this way, the high level of performance of modern computers is combined with the robustness of industrial devices.
