0.175 mm pitch ultra-low profile FPC LIF back-lock Connector 【Upper Contact Type】 FF27 Series OUTLINE The FF27 series ultra-low profile FPC LIF connector has a market leading height of only 0.66mm with a depth of just 3.80mm. The cable lock mechanism provides maximum FPC circuit retention and alignment of the material. DDK's FF27 LIF 0.175mm connector mates with an FPC circuit of 0.12mm thick. The upper contact is utilized as the electrical contact for the FPC material. FEATURES ・DDK's original cam-type "Back-lock" system ensures a reliable connection and continued retention from inadvertent upward pulling of the FPC. ・The FF27 FPC LIF connector has a pitch of 0.175mm and a mounting height of 0.66mm. ・DDK's cable lock mechanism provides positive retention of the FPC. ・Back-lock structure ensures retention from inadvertent from upward pulling of the FPC. ・The upper contact is used for electrical contact with the FPC circuit. ・Connectors are delivered unlocked, so the lock lever does not need to be opened before operation. ・Supplied with emboss tape for automatic mounting. ・Nickel barrier prevents solder wicking. ・Halogen Free ・The housing and lock lever are made of heat-resistant resin making the FPC connector compatible with lead-free reflow soldering. Note: ※ Please do not close the lock lever without inserting the FPC. ※ Since the cable lock tabs electrically conductive on both ends, please do not use the cable lock tabs as ground tabs.

Due to the semi-retaining mechnism, some insertion force is necessary when inserting FPC. FPC insertion is completed when the edges of the FPC are ouching connector frange. （ picture ⑤） Stiffener side Pattern side NG picture ③ picture ② 3．Correct FPC Insertion Position ・The frange position enables a visual verification of the mating position.(figure ⑤）. It prevents shallow and diagonal insertion.（ picture ⑥、⑦） FPC frange figure ⑤：normal insersion figure ⑥：Shallow insertion figure ⑦：Diagonal insertion ・If cable lock tabs catch the FPC correcty, FPC patterns are not dislocated from contacts. ◎ Specifications and/or dimensions in this catalog are subject to change without notice.
