306-023-521-108

Overview

The EDAC Inc. model 306-023-521-108 is a standard card edge connector from the 306 series, designed for vertical panel mounting applications. This receptacle features 46 positions arranged in a dual-row configuration with a 0.156-inch (3.96 mm) pitch. It utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and includes a green thermoplastic insulator housing. The component supports a maximum current rating of 5 A and offers an insulation resistance of 5 GOhms. Designed for robust industrial environments, it accommodates board thicknesses up to 1.57 mm and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female contact design ensures secure mating with double-sided card edge PCBs
• Gold-plated copper alloy contacts provide durable conductivity and corrosion resistance
• Vertical panel mount style with threaded insert flange facilitates stable mechanical installation
• Green thermoplastic insulation material meets high dielectric strength requirements

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board interfaces
• Consumer electronics module connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pin count, plating type, and flange configuration. Ensure compatibility with the target PCB thickness and mounting hole specifications. Confirm RoHS compliance status if required by project regulations. Cross-reference the part number with authorized distributors to avoid counterfeit components. Check for any recent design changes or obsolescence notices before finalizing procurement.

Selection Notes

Select this connector when a dual-row, 46-position interface with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current capacity and 5 GOhm insulation resistance for electrical safety margins. The green thermoplastic housing and gold contacts suit environments requiring moderate durability and reliable performance. Evaluate the -40°C to +105°C operating range against environmental conditions. Ensure the panel cutout dimensions align with the flush-mount flange specifications.
