306-034-421-103

Overview

The EDAC Inc. 306-034-421-103 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 68 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The contacts are made of copper alloy with a tin finish, utilizing a cantilever design. The insulator is constructed from thermoplastic polyester, colored green, and supports PCB thicknesses between 0.054 and 0.070 inches. Operating temperature ranges from -40°C to 105°C.

Feature Summary

• Dual-edge female configuration with cantilever contacts for secure board retention
• Through-hole termination compatible with standard panel mounting flanges
• Tin-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester insulator body rated for high-temperature environments

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to confirm pin count, termination style, and plating specifications. Ensure compatibility with the target printed circuit board thickness range of 0.054 to 0.070 inches. Confirm that the required operating temperature range aligns with the component's -40°C to 105°C rating before finalizing procurement orders.

Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required for through-hole panel mounting. The 68-position capacity suits applications needing moderate I/O density. Verify that the cantilever contact type matches the mechanical retention requirements of the assembly. Ensure the green thermoplastic polyester insulator meets environmental and thermal constraints of the specific deployment scenario.
