This specification covers the requirements for application of Micro MATE-N-LOK connectors for printed circuit (pc) board, panel mount, and free-hanging applications. Connectors are available in dual row with 2 through 24 contact positions, and single row with 2 through 12 positions on 3.00 mm centerline spacing. End cavities are marked with a number to provide circuit identification. The pin header is available, for wire-to-board applications, in vertical or right-angle configurations for through hole mount application or surface mount technology (SMT). The plug housings are available for panel mount or free-hanging wire-to-wire applications. The receptacle locking latch ensures positive mating of the connectors.
