TE Connectivity AMP offers Standard Edge II Connectors with or without mounting ears, for rack mounting and soldering. Contacts are arranged on .100 [2.54] centers, .200 [5.08] row-to-row; and .125 [3.18] centers, .250 [6.35] row-to-row. Right-angle connectors are also available with contacts arranged on .100 [2.54] centers, .150 [3.81] row-to-row or .200 [5.08] row-to-row. Card extenders with contacts on .100 [2.54] and .125 [3.18] centers also are available. Precision formed phosphor bronze contacts are selectively gold plated. Phosphor bronze has excellent strength characteristics which help the connector absorb load deflection movement of a pc board while maintaining sufficient contact force for good electrical connection. Bifurcated cantilever beam contacts provide redundant contact.
