1. Preface
1-1 Purpose
The FX23xFX23L Series Instruction Manual is intended to provide information on basic features of
the FX23 and FX23L Series and the method of use, as well as to provide information on the
method of designing products efficiently and improving the assembling process when the
FX23xFX23L Series are used.
Hirose expects this Instruction Manual will significantly contribute to your product development,
quality, and cost reduction of the entire system.
Because this Instruction Manual intends only to provide general information, it does not restrict
your design and does not guarantee results in all circumstances.
If there is anything that does not conform to the description in this Instruction Manual, consult
Hirose for alternative solutions.
1-2 Scope
Described is basic connector design information, recommended board dimensions, and
requirements.
This Instruction Manual will be revised on a continuing basis as technical specifications and
manufacturing capability changes.

2-7 Floating Range
FX23 and FX23L Series have a floating capability on the header and receptacle side, respectively.
The floating range is ±0.6mm in both X and Y directions.
Note that the repeat count of the floating operation is 100 times at maximum according to the
specified insertion/withdrawal count.

The connector can be rotated in parallel with the board surface.
The rotation angle varies by the number of pins. See the table below.

Rotation angle (MAX): FX23L Series 6.0°4.3°3.4°2.8°2.6°2.0°
* These values are obtained with the rotation center placed at the center of the connector. When the
rotation axis is at a position other than center, the rotation range becomes narrower than the above value.

2-8 Use of Insulation Coating Agent
FX23 Series --- Can be used
FX23L Series --- Cannot be used
FX23 Series have spaces around the contacts to prevent insulation coating agents from creeping up
due to capillarity.
FX23L Series, which has a lower height, does not have spaces like FX23 Series.
Thus, FX23L Series is not designed for preventing insulation coating agents from creeping up.
When an insulation coating agent creeps up, it may have adverse effects, such as contact failure by
disturbing contact displacement and loss of floating movement.
For this reason, avoid applying an insulation coating agent for FX23L Series.
Spaces around contacts prevent coating agents from
creeping up due to capillarity.
◆FX23 Series
◆FX23L Series No space around contacts due to lower height.
Since the spaces between the boards and contacts are limited, FX23L Series
cannot prevent coating agents from creeping up.
