The 0.5-5 Floating Series is a 0.5 mm-pitch high-speed floating board-to-board connector family available in SMT and through-hole (THR) versions. Its XY ±0.6 mm floating structure absorbs board misalignment, while supported double-floating combinations provide up to XY ±1.2 mm movement. The family covers multiple 20- to 120-contact configurations and 8–30 mm mating heights, with ratings of 0.5 A per contact and 50 V AC/DC, data rates up to 8 Gbps, and an operating temperature range of -55°C to 105°C. It suits equipment requiring flexible stack heights, high-speed links, and tolerance to assembly misalignment.
