The 3-487937-0: This is a 30-position, dual-row FFC receptacle housing from the AMPMODU System 50 series, built for 0.050" (1.27mm) pitch ribbon cable. It accepts FFC thickness from 0.05-0.08mm and uses a latch lock to hold the mated pair together — no secondary clip needed. The critical note: contacts are not included. Confirm your BOM includes the contact part number before you commit.
Pitch and position count — board fit
At 0.050" (1.27mm) pitch with 30 positions in two rows, this housing mates to a 15-per-row footprint. The dual-row layout halves the board-edge length compared to a single-row 30-position connector at the same pitch — useful when you're tight on PCB real estate. The latch lock adds a positive mechanical retention that resists vibration-induced disconnect. For a harness that sees movement or shock, that latch is your insurance against intermittent signal loss.
