Transportation applications present the most exacting requirements for any equipment, in terms of resistance to shock, vibration and long-term corrosion. At the same time, PCB interconnections in electronic racks are often mission-critical to communications systems and power supplies. The use of the Hyperboloid contact design dramatically reduces overall wear rate and the fretting that can lead to long-term corrosion damage, making these connectors highly suitable for use in mass transport rolling stock, signalling and line-side electronic equipment, military/aerospace and naval applications.
The connectors, designated the HDB, HDC, HDD, HDS and HDT series, are available in two- or three-row formats with a maximum of 192 positions. Designers can choose between two pin pitches – 2.54mm and 5.08mm. The HDT style offers mixed contact arrangements that combine signal, power and up to 12 co-axial contacts.
Pin diameters of 0.6mm, 1.0mm and 3.6mm offer (respectively) contact resistance of 7, 3 and 1mohm maximum, and current handling capabilities of 4A, 7.5A and 10A. This exceptional performance allows more current carrying capability within a given space envelope, bringing space savings and simplifying design.
Thanks to the use of Hyperboloid contact technology, the connectors can endure in excess of 2000 mating cycles with no adverse effects and are rated for use across the -55°C to +125°C temperature range. In addition to conformance with industry standard DIN 41612, this connector range is designed to sustain electrical integrity under the most demanding conditions of extreme shock and vibration.
To provide further design flexibility, the Hypertac DIN41612 range of connectors is available in a choice of board- or panel-mounted formats and as a free connector with plastic cover. Other accessories include Double Eurocard aligners: custom requirements can be accommodated on request.
