Surface-mount termination, vertical orientation, 0.201" (5.10 mm) height above board. Compared to the right-angle sibling 12FMN-SMT-A-TF (3.00 mm height, top-contact entry), this vertical part takes more z-height but allows the FFC to exit straight up, which can simplify cable routing in tight enclosures.
The peer 12FMN-BMT-A-TF(LF)(SN) is the RoHS-compliant version of this exact connector — same pitch, position count, and vertical SMD footprint. Swap the BOM line to that order code if your assembly requires RoHS.
It uses a Low Insertion Force (LIF) mechanism — the FFC slides in and is held by friction and the contact beam. There is no secondary locking latch; vibration resistance depends on the cable strain relief in your assembly.
