302-022-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-022-621-201 is a standard card edge connector from the 302 Series, designed for dual-edge non-specified cards. It features 22 positions with a female contact type and a 0.050 inch (1.27mm) pitch. The connector utilizes gold-plated contacts on a black polyamide (PA66) housing. It supports board thicknesses between 0.051 and 0.071 inches (1.30mm to 1.80mm). The component operates within a temperature range of -55°C to 85°C and employs a solder termination method.

Edgeboard Connectors Feature Summary

• Dual-row configuration with vertical staggered PCB tails for secure mounting
• Gold flash plated contacts ensure reliable signal transmission
• Housing constructed from black polyamide (PA66) nylon 6/6 material
• Designed for non-specified dual-edge card insertion without mounting lugs

Edgeboard Connectors Applications

• Industrial control system interconnects
• Medical device circuit board connections
• Telecommunications equipment backplanes
• General-purpose electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 22-position configuration and dual-edge compatibility. Confirm that the gold plating finish aligns with environmental requirements. Ensure the operating temperature range meets the application's thermal specifications. Check RoHS compliance status if restricted substances are a concern. Validate that the supplier provides official documentation for quality assurance.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge card interface with a 1.27mm pitch is required. Consider the 22-position count for circuit density needs. Evaluate the gold contact finish for corrosion resistance in harsh environments. Assess the PA66 housing material for mechanical stability. Verify compatibility with the target card thickness range of 1.30mm to 1.80mm.
