Question about flex cables/ribbons
Question about flex cables/ribbons
Just to confirm, are you asking about whether the measurements refer to the length of the pins or their thickness? It shouldn't be the thickness, should it?
I’m trying to swap one of the connectors for the touch-pad, which uses four pins. I think this is the right part to replace:

The distance of the pins is 0.5 units. A 1mm seems appropriate, but it could also be 1.25—it's all a bit confusing, right?
What I discovered is that the "pitch" of a ribbon cable describes the gap between the parallel wires inside the cable. A typical pitch is 0.05 inches (1.27 mm). Other options include 0.5mm, 1.0mm, and 1.25mm, with specialized cables also offered. The pitch is generally measured from the center of one wire to the center of the next.
What it entails:
Pitch signifies how much space exists between the centers of adjacent conductors in a ribbon cable. This measurement defines the arrangement and separation of the individual wires within the flat cable structure.
Why it’s important:
The pitch affects how many conductors can fit inside the cable’s width and influences the connector type that can be paired with it.
Common pitches:
0.05 inches (1.27 mm): A widely used standard for ribbon cables, especially in electronic assemblies.
0.5mm: Suitable for compact designs where space is limited.
1.0mm: Frequently seen in flat flexible cables (FFCs).
1.25mm: Applied in certain FFC configurations.
How to determine:
The pitch can be measured by calculating the distance between the outer edges of the cable and dividing it by the number of conductors.
