Overview
The EDAC Inc. 306-021-420-168 is a dual-sided edgeboard connector featuring 42 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes female, cantilever contacts made of copper alloy with gold plating for reliable signal transmission. Designed for through-hole termination, the unit accepts printed circuit boards with thicknesses ranging from 0.062 to 0.071 inches. The insulator body is constructed from thermoplastic polyester, ensuring stability across an operating temperature range of -55°C to 85°C.
Feature Summary
- Dual-sided configuration with 42 positions for comprehensive board connectivity
- Cantilever contact design ensures secure mating and electrical continuity
- Gold-plated copper alloy contacts provide corrosion resistance and low contact resistance
- Thermoplastic polyester insulation supports stable performance in varied thermal environments
Applications
- Industrial control systems requiring robust edge card connections
- Communication equipment interface modules
- Consumer electronics internal board interconnects
