Stacking Height 5 to 11mm Half Pitch Connector FX4 Series Stacking Height Flexible 5 to 11mm DIP type 6 to 11mm SMT type The mounting area 70% reduced, compared with conventional product (FX2 series) FX2 series FX4 series (Compared with 60 contacts) ■Features 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. ■Applications Computers, peripheral equipments, business equipments, etc. A189 ■Product Specifications Rating Current rating 0.5A Operating Temperature Range -55ç to +85ç (Note 1) Storage Temperature Range -10ç to +60ç (Note 2) Voltage rating 125V AC Operating Humidity Range 40% to 80% Storage Humidity Range 40% to 70% Item Specification Condition 1.

Tolerance Clearance on Mating Side The effective connecting length of the product is set to 1.5mm. Please use the product to specify the clearance between the header and the receptacle in the connection process within 1mm. 2. Prefixed Process to Board (Through hole Type) If the prefixed work is required for mounting on the board, please use the prefixed pin type. (Applicable board thickness t = 1.6±0.1) Cautions:When the connector is installed in the board, the dip post is guided into the board through-hole in order to prevent the dip post breakage, and then insert the board in parallel to the connector so as to push in the prefixed pin. 3. Temperature Profile (Reference) Temperature (ç) Applicable Conditions Reflow system : IR reflow Solder : Paste type 63 Sn/37 Pb Test board : Glass epoxy 110mm x 40mm x 0.8 mm (Flux content 11 wt%) Metal mask thickness: 0.2 mm Recommended temperature profile. The temperature may be slightly changed according to the solder paste type and amount. In addition, the temperature profile as shown left will be variable in 5% less or more according to number of contacts, height or other factors. Note: The heat-proof cover is also equipped on the header side. A205
