0.25 mm Pitch Ultra-low Profile FPC Back-lock Connector FF28 Series【Upper Contact】 OUTLINE FF28 series is 0.25mm pitch, denpth 3.80mm and 0.66mm connector height. And cable lock mechanism reinforce the retaining force of FPC by cable lock tabs on both ends of the contact. It is achieved both ultra-low profile and high retaining force. FEATURE ・DDK's original rotate oval cam lock mechanism; "Back-lock" system ensure the reliable connection. ・DDK's original cable lock mechanism solves retaining force shortage of FPC. ・The contact position is upper contact. ・Back-lock structure enables to retain FPC against pulling upward direction. ・Connectors deliver with the lock lever opened. Time saving for FPC inserting operation. ・Halogen free Note : Please do not close the lock lever without inserting the FPC. Since cable lock tabs electrify next contacts, please do not use the cable lock tabs as ground tabs.
