With the FR 1.27 series, Phoenix Contact is launching new board-to-board male and female connectors onto the market. While maintaining established market standards in terms of component dimensions, different mating directions and stacking heights can be realized with pin counts between 6 and 100 contacts.
Gold-plated contact zones enable long-term stable signal transmissions of up to 28 GBit/s. The upper limit of the rated current is 2.3 A per contact for a fully energized connector. If, for example, 6 poles are energized, 3.7 A per contact can be achieved (at an ambient temperature of 20 °C), see diagram. Customer-specific variants enable leading contacts for hot-swapping and increased creepage distances for higher voltages by partially populating the contacts. The SMT components are specified for up to 3 reflow soldering processes. The end surface is gold over nickel in the contact area and tin over nickel in the soldering area. The minimum value of the clearance and creepage distance is 0.42 mm, the insulation resistance between adjacent poles is more than 5 GOhm. The number of mating cycles is specified at 500, the operating temperature range is -55 °C ... 125 °C.
