4-position 1.00mm pitch vertical FFC connector
The 1735042-4: This is a 4-position FFC/FPC connector on 1.00mm pitch, mounted vertically to the board. The pitch sets the cable width and the SMT footprint — at 1.00mm it matches standard 4-conductor FFC with 0.30mm thickness. The vertical orientation keeps the cable perpendicular to the PCB, useful when the cable exits upward into a tight enclosure. Rated 1A per contact with a 125V voltage rating, the connector handles low-power signal and control lines — think sensor inputs, LED indicators, or configuration jumpers. Tin-plated phosphor bronze contacts keep the cost down for moderate mating-cycle applications. The housing is glass-filled nylon (PA), UL94 V-0 rated for flame resistance inside enclosed equipment.
Board-fit and z-height budget
Height above board is 5.59mm — this is the space the connector claims above the PCB surface. In a mezzanine or stacked-board layout, that z-height must clear the adjacent board or cover. The contacts are vertical, 1-sided — the FFC/FPC inserts straight in and contacts one side only. That means the cable's exposed pads must face the contact beam side. Orientation matters at assembly: flip the cable and the circuit won't connect.
