302-012-658-201

Edgeboard Connectors Overview

The EDAC Inc. 302-012-658-201 is a standard card edge connector from the 302 Series, designed for reliable signal transmission in electronic assemblies. It features a dual-edge configuration with 12 positions arranged in two rows of six contacts each. The connector utilizes a 0.050-inch (1.27mm) contact spacing to accommodate high-density board layouts. Contacts are female type with gold plating to ensure low contact resistance and corrosion resistance. The housing is black polyamide (PA66), providing thermal stability and mechanical strength.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure mating with non-specified double-sided card edges
• Gold-plated cantilever spring contacts ensure reliable electrical connection and durability
• Black polyamide insulation offers structural integrity and heat resistance
• Right-angle termination facilitates efficient PCB routing and space-saving installation

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module interfaces
• Automotive electronic circuit boards

Edgeboard Connectors Procurement Notes

Verify that the target application requires right-angle termination, as this specific part number differs from the straight-mount variant 302-012-256-201. Confirm compatibility with the intended PCB thickness range of 0.051 to 0.071 inches. Ensure the design supports the 0.050-inch pitch constraint. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a compact, right-angle interface is required for double-sided cards. The 12-position count suits moderate I/O density needs. The 0.050-inch pitch allows for tighter board spacing compared to larger series. Gold flash plating is suitable for low-to-medium current applications requiring stable signal integrity without heavy oxidation concerns.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 Series, which specializes in small-pitch card edge solutions. The series includes various pin counts and mounting styles. This specific model represents the right-angle variant, distinguishing it from the more common straight-mount versions like the 302-012-256-201. It is part of a standardized lineup used across multiple industrial sectors.

Edgeboard Connectors FAQ

What is the difference between 302-012-658-201 and 302-012-256-201?

The primary difference is the termination style. The 302-012-658-201 is a right-angle connector, while the 302-012-256-201 is a straight-mount connector. Both share the same 12-position, dual-edge, and 0.050-inch pitch specifications.

Is this connector compatible with single-sided card edges?

No, this is a dual-edge connector designed specifically for double-sided card edges. Using it with a single-sided card may result in improper alignment or insufficient contact engagement.
