The FX4 series is a miniature board to board connectors, where the stacking height can be set at the 1mm interval. According to the mounting method, you can select the product from the through hole type and SMT type.

●Through hole Type

1. Small and Light

The mounting space and weight is reduced about 30, compared to the conventional product (HRS FX2 series), respectively, and the mounting area about 70 reduced, compared to the conventional one.

2. Stacking Height 5 to 11mm

The board to board stacking height can be set per 1mm from 5mm up to 11mm.

3. Flux Swell Prevention

When solder is dipped, the flux swell from the board rear side is completely prevented.

4. Mis-insertion Prevention and Low

Insertion/Extraction Force Mechanism The connection area is designed to completely prevent the

mis-insertion. Moreover, the low insertion/extraction mechanism is adopted.

●SMT Type

1. Small and Light

The mounting space and weight is reduced about 40, compared with the conventional product (HRS FX2 series), and the mounting area is reduced 80, compared to the conventional one.

2. Stacking Height 6 to 11mm

The board to board stacking height can be set per 1mm from 6mm up to 11mm. In addition, the height can be also set in combination with the through hole type.

3. Mis-insertion Prevention and Low

Insertion/Extraction Structure The connection area is designed to completely prevent the mis-insertion. Moreover, the low insertion/extraction force mechanism is adopted.

4. Positioning Boss Selectable

According to the mounting condition, it is selected whether or not the boss is required. Regarding the boss attached type, the boss eccentric position can stabilize the mounting direction.
