Otto Marketing is supplying the HiRose FH42 and FH43B series of miniaturised back-flip FPC connectors.
The FH42 features 11, 19, 23 and 31 contact positions and has a height profile of 0,65 mm, double-sided leads and top contact, while the FH43B offers 21, 25, 29, 31, 35, 41, 51, 61 and 71 contact positions, 0,9 mm height and bottom contact.
Both series are rated for 0,2 A and 30 V. Although compact in size the connectors are easy to mount on the PCB with double-sided contacts. The fully enclosed moulded housing structure conceals the exposure of contacts on the bottom face of the connector, allowing conductive traces to run underneath the connector. Solder wicking is prevented by the application of a nickel barrier on the contacts to prevent the travel of solder into the mating contact area.
The insertion of the FPC is user friendly due to the wide housing entry and tapered contacts that allow the FPC to be inserted from a steeper upright angle. This allows other components to be placed closer to the connector entrance.
In addition, it is also possible to insert the FPC horizontally thanks to side-catches that have been designed with a curved surface to permit correct positioning of the connector. When the FPC travels over the side-catches an audible and tactile click confirms correct mating.
For additional security, a special cut-out in the housing allows a visual window to verify the FPC is positioned correctly. A high retention force of 7,25 N (31 position, horizontal direction) is achieved due to the inclusion of metal fittings situated internally on each side of the housing to hold the FPC tabs firmly in place.
The unique shape of the contacts supports FPC retention. Applying pressure on to the FPC further increases the retention. In addition, the contacts fully support the back-flip actuator axle during rotation, making it more secure and highly durable.
The FH42 and FH43B connector series are well suited for LCD displays, digital cameras, PDAs, POS terminals and many other small portable devices where their small size proves advantageous.
