FH34 FPC/FFC ZIF Connectors Hirose FH34 FPC/FFC ZIF Connectors are 0.5mm pitch low-profile connectors with a height of 1.0mm above the board and a width of 3.8mm, making them ideal for space-saving applications. These back-flip connectors are compatible with 0.3mm thick FPC/FFC and feature both upper and lower contacts. The FH34SRJ series provides increased FPC/FFC retention horizontally and vertically than other connectors with similar construction. The FH34D connectors come with tabs for improved FPC retention force. Hirose FH34 series connectors are delivered with the lock open, so there is no need to open the actuator before working.
