When water-type cleaning agents (terpene, alkaline saponification agents) are used, select cleaning agents basedon the 'table of influence' on metals and resins issued by the cleaning agent manufacturer.
Caution : Do not leave with any water content left.

●Cleaning Precautions
When cleaning the parts with organic solvents and water-type agents, if flux or cleaning agents remain in theconnector, it could cause the deterioration of electric performance.
Please be sure to check if adequate cleaning has been completed.

FX27 Series●0.8mm Pitch Floating Card Edge Connector●Securing Boards
Using only connectors is not recommended. The board is designed to be secured with a spacer.
If the board is supported only by the connector, an excessive load may be applied to the connector which may
result in damage or contact failure.
Take measures to secure the board other than using the connector.

●Mating Precautions
・The self-alignment range is ±0.7mm in the X and Y directions.
Insert the connector straight in without applying excessive load during mating.

Sep.1.2024 Copyright 2024 HIROSE ELECTRIC CO., LTD. All Rights Reserved.

Taper : 0.7mm

・It is recommended that the connector be inserted and removed
straight without tilting the connector.

X direction(Longitudinal)

Y direction(transverse direction)●Misalignment allowance in Mated Condition (Floating Amount)Since this connector has a floating structure, the maximum allowable PCB misalignment amount is ±0.6mm in the X
and Y directions when mated.
When two FX27 connectors are used for stacking connections, they have a double floating capability, allowing for a
maximum PCB misalignment of ±0.12mm in the X and Y directions.
However, this product cannot be used to absorb misalignment when there are constant changes due to vibration, etc.
Be sure to secure the boards after mating.
The floating operation can be repeated 100 times max. based on the connector durability (insertion/extraction times).
