Many applications require a wire-to-board connector that is sub-miniature in size and offers engineers design flexibility. The PA series of wire-to-board connectors are available in SMT and through-hole versions and are interchangeable between the crimp style PA and the IDC PAF style. They incorporate both a polarization and a secure locking feature. Additionally, the series features secondary retainers to enhance safety in case of partial insertion or accidental release of the contact from the housing.
