The 65801-037LF is an 8-position FFC/FPC receptacle from the Clincher™ series by Amphenol ICC (FCI). It accepts 0.20 mm thick flat flex cable with a tapered end, and the flip lock secures the cable without a secondary actuator — quick to engage on the line or in the field.
The 0.20 mm FFC thickness is a common standard for signal-level flex circuits; the tapered cable end aids insertion into the flip-lock mechanism.
The 7-position 65801-036LF and the 11-position 65801-040LF are direct position-count alternatives — same footprint width per position, same cable thickness, same mating cycle rating.
