306-034-420-112

Overview

The EDAC Inc. 306-034-420-112 is a dual-edge female card edge connector from the 306 Series, designed for panel mount and through-hole termination. It features 68 positions (34 per row) with a 0.156" (3.96mm) contact spacing. The connector utilizes tin-plated copper alloy cantilever contacts and a green thermoplastic polyester insulator. It accommodates PCB thicknesses of 0.054" to 0.070" (1.37mm to 1.78mm). Operating temperature ranges from -40°C to 105°C, and it complies with RoHS3 standards.

Feature Summary

• Dual-edge female configuration with cantilever contacts for reliable board insertion
• Panel mount installation with flush flange and top opening design
• Tin-plated copper alloy terminals ensuring stable electrical performance
• Thermoplastic polyester insulation body providing durability in industrial environments

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard double-sided PCBs
• Test and measurement devices needing high-density signal connections

Procurement Notes

Verify that the specific part number matches the required pin count and termination style before ordering. Confirm compatibility with the target PCB thickness range of 1.37mm to 1.78mm. Ensure the application environment falls within the specified operating temperature limits. Check for any specific packaging requirements if bulk quantities are needed. Cross-reference the manufacturer's latest datasheet for updated compliance information.

Selection Notes

Select this component when a dual-edge female connector with 68 positions is required. Ensure the design supports panel mounting and through-hole soldering processes. Verify that the PCB material and thickness align with the connector's mechanical specifications. Consider the tin plating option if gold plating is not strictly necessary for the application. Confirm that the 0.156" pitch fits the existing layout constraints.

Part Context

This connector belongs to the EDAC 306 Series, which offers various configurations for card edge applications. The series provides options for different pin counts, termination styles, and mounting methods. The 306-034-420-112 specifically addresses needs for dual-edge connections with a standard 68-position layout. It is part of a broader family of connectors designed for reliability in demanding electronic assemblies.

Replacement Considerations

Direct substitutes within the same series include 306-034-420-104 and 306-034-421-104. These alternatives may differ in contact plating or flange characteristics. Verify mechanical dimensions and electrical ratings before swapping components. Ensure that any replacement maintains the same dual-edge female configuration and mounting style.
