306-029-421-104

Overview

The EDAC Inc. 306-029-421-104 is a dual-edge female card edge connector designed for panel mount and through-hole termination applications. It features 58 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The unit operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Feature Summary

• Dual-edge female configuration with cantilever contact type for secure board insertion
• Panel mount installation with flush flange featuring top opening and no threading
• Tin-plated copper alloy contacts housed in a green thermoplastic polyester body

Applications

• Industrial control systems requiring robust edge board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm pin count, spacing, and termination style match design requirements. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm that the tin plating and operating temperature range meet environmental specifications. Check for any recent product change notifications or lead time updates directly from the manufacturer before finalizing procurement orders.

Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required for panel-mounted applications. It is suitable for designs needing through-hole soldering and a low-profile insulator body. Consider the thermal rating and material composition if operating in environments exceeding standard temperatures. Verify that the non-specified card type aligns with the mechanical constraints of the mating edge board.

Part Context

This component belongs to the EDAC 306 series of edgeboard connectors, which are standardized for general-purpose electronic interconnections. The series offers various position counts and spacing options to accommodate different board densities. The 306-029 variant specifically addresses mid-range pin count requirements with a focus on durable mechanical engagement and reliable electrical performance in industrial settings.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with differing pin counts or spacing. Cross-reference with other manufacturers only if mechanical dimensions and electrical ratings are identical. Verify that any alternative maintains the same termination style and mounting configuration.
