FH12-22S-0.5SH(55)

Hirose Electric FH12-22S-0.5SH(55): FFC/FPC connector, 22 positions, 0.5 mm pitch, bottom contact.

Hirose FH12-22S-0.5SH(55) is a 22-position, 0.5 mm pitch FFC/FPC connector with a flip-lock actuator, right angle, bottom contact, surface mount. It takes 0.3 mm FFC/FPC cable with gold-plated contacts.

The (55) suffix is part of the orderable part number (Hirose product code CL0586-0532-7-55). The wiki slug drops the punctuation; the page MPN keeps the exact string.

Pins

22 contacts numbered 1 to 22 (contact 1 at the polarization-mark end) plus MP, the two fitting-nail mounting pads. Each contact connects straight to the matching FFC/FPC conductor.

Design notes

• Contact 1 is at the polarization-mark end of the actuator. The fitting nails (MP) solder to the two mounting pads; tie them to ground or leave them unconnected as the design needs.
• The housing rear edge was placed at the inner (body-side) end of the signal pads, following the dash-dot connector outline on drawing sheet 1. Paste uses the full copper pad; the drawing's stencil pattern shows 0.25 mm wide signal apertures if a reduction is wanted.

3D model

The 3D model is AI-created from the manufacturer drawing, not a manufacturer model. The manufacturer's own model is not redistributed (its download terms grant no redistribution right). Box housing 14.1 x 4.6 x 1.85 mm with the FFC slot (11.57 mm wide), dark actuator lip and cover (12.9 mm wide, to 2.0 mm), a shallow polarization mark at the pin-1 end, metal fitting nails to 15.1 mm, 22 flat contact tails 0.2 mm wide projecting 0.8 mm. No internal contacts or lock details.

• Frame: Adom Z-up, millimetres, seating plane z = 0, origin = footprint origin, identity footprint binding. Extents: 15.1 x 6.4 x 2.0 mm, seated on z = 0.
• Cross-check against the manufacturer model (not included): Hirose STEP overall 2.1 x 6.4 x 15.1 mm (checked, not included): this model 2.0 x 6.4 x 15.1 mm, height per the drawing's 2.0 mm.
• Virtual MPN mark (identification aid, not a claim about the real part's marking): On the actuator top (light mark on the dark actuator), clear of the polarization mark. Placed with adom-aiflow-etch; the plan and gate report are in provenance/etch/.
