Title
Detail Specification for the Interface of the 1.27 mm Pitch, Ribbon Contact (Leaf Spring), Trapezoidal Shaped, Self-Locking I/O Connector

Electronic Components Association

Publication Date:
Nov 1, 1997

Scope:

This specification covers rectangular self-locking connectors with ribbon style (leaf spring) connector contacts on 1.27 mm (0.050 in) contact spacing. Connector polarization is achieved by the trapezoidal configuration of the insulator. The straight or right-angled receptacle header (fixed connectors) with contacts is soldered to the printed board. The plug (fiee connector) with contacts uses the insulation displacement or compression type of termination for round cable with 0.09 mm2 (28 AWG) discrete solid or stranded conductors. It is recommended that the user have their cable evaluated by the connector manufacturer for their specific application. The specification covers the following:

1) sizes 20 and 26;

2) self-locking hardware only;

3) over-molding to be shown only as an application note with maximum dimensions only;

4) cable connectors, straight and right angle headers are to be covered;

5) headers to be suited for soldering to single, as well as double-sided printed boards.

The application of this range of connectors includes use for signals in telecommunication and information processing equipment and systems, and other electronic devices employing similar techniques.
