FX20 Series, 0.5mm Pitch, Floating, Board to Board Connectors

The FX20 series has been introduced to meet the requirement for floating connectors that can absorb mounting misalignment in applications where multiple stacking connectors are used.

the fixed base of the housing. This allows an alignment movement in XY
directions of + 0.6mm minimum to absorb mounting misalignment,
vibration and dimensional errors. Large mating guides on each side of
the connector allow for a alignment movement of + 1.2mm in XY
directions to simplify the mating operation and prevent incorrect insertion.
The receptacle features highly reliable double beam contacts. Each
contact beam has a different vibration characteristic due to different
contact forces that widens the frequency range to avoid resonance. This allows high vibration resistance and
increased contact reliability. Furthermore the first beam contact has a self-cleaning function which eliminates dust
from the contact path of the second beam contact. Although the 0.5mm pitch is fine, each contact has the current
handling capacity of 0.5A (amps).
The contact area is protected from solder wicking and penetration of flux due to the clearance between the
contact and housing to prevent capillary action. The board layout design allows board patterning underneath the
connector for design flexibility.
Hirose’s popular FX18 high speed, board to board connector series shares the same stack height variants as
FX20, therefore both can be combined on the same board to offer a flexible high speed capability.
Ideal applications are industrial equipment, broadcast equipment, smart meters, medical devices, BTS, measuring
instruments and projectors.
