Flex circuit connectors are available in multiple contact spacing options, ranging from 1.25mm  down to 0.20mm. There are connectors for flexible circuitry with larger contact spacing (2.54mm) but they are typically two piece connector solutions. Contact spacing, also referred to as pitch, is the distance between contacts in the same row measured center to center. The contact spacing chosen usually reflects the application’s demand for printed circuit board space. For example, the designer of a handheld device places a premium on getting the maximum number of components in the smallest package.
