Connectors for frequencies below 3 MHz for use with printed boards; part 2: two-part connectors for printed boards, for basic grid of 2.54 mm (0.1 in) with common mounting features

This technical specification outlines requirements for connectors designed specifically for use with printed boards operating at frequencies below 3MHz. Focused on the second section of a broader series, it defines two-pair connectors that share common mounting characteristics on a 2.54mm (0.1in) basic grid. The document details the mechanical dimensions, electrical performance criteria, and interface compatibility necessary to ensure reliable signal transmission in electronic assemblies. It specifies the geometric arrangement and physical properties required for mating components, ensuring interchangeability across different manufacturers. The standard establishes testing procedures to verify dimensional accuracy and electrical continuity under specified conditions. By adhering to these guidelines, designers can ensure that connectors fit precisely onto printed circuit boards with the defined grid spacing. The content covers insulation requirements, contact resistance limits, and mechanical durability expectations. These specifications support the integration of various electronic systems where consistent interconnection is vital for operational stability. The guidelines address both the structural integrity and the functional performance of the connector system within the specified frequency range.
