POWER CONNECTORS- This 8-1/2" x 11" cardboard "slide-rule" nomogram is a quick-reference guide to thousands of the firm's power connectors rated at 5A or higher. The inner part of the chart is a cardboard panel marked with indicator lines and part numbers. This panel is sandwiched between two outer cardboard panels marked with part identifiers and drawings. The outer panels have strategically placed cutouts that reveal the inner panel's markings. Sliding the inner panel aligns the information on the inner and outer panels, allowing the user to select the right housing and terminal for almost any use.
