NSCC Unsealed Connectors Molex NSCC Unsealed Connectors are a cost-effective, compact solution for small circuit-size applications. The one-piece design with integral hinged TPA makes assembly at the harness maker quick and simple. Power is carried through 1.50mm and/ or 2.80mm terminals. Molex's robust clean-body female terminals allow for smooth terminal entry. NSCC connectors must use male SICMA terminals from FCI.
