FX20 0.5mm Floating Stacking Connectors

Hirose FX20 0.5mm Floating Stacking Connectors feature a double beam structure that provides a minimum of +/- 0.6mm float in the XY directions. These connectors offer 0.5mm pitch, a self-cleaning function, vibration resistance, +/- 1.2mm self-alignment for easier mating and a current capacity of 0.5A / pin. The contacts for both header and receptacle are enclosed in a non-flowable housing for dust protection. Hirose FX20 connectors are available in four stacking heights in 15mm, 20mm, 25mm, and 30mm PCB distances.
