305-076-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-076-521-512 is a standard card edge connector featuring 76 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts PCBs with thicknesses between 1.37 mm and 1.78 mm. The component employs gold-plated copper alloy contacts for reliable signal transmission and supports a continuous current rating of 5 A. Designed for panel mounting, it offers vertical orientation and solder pin termination to ensure secure mechanical and electrical connections.

Edgeboard Connectors Feature Summary

• Dual female contact configuration designed for non-specified dual-edge card insertion
• Gold-plated copper alloy contacts provide corrosion resistance and stable conductivity
• Thermoplastic polyester housing ensures structural integrity within specified temperature ranges
• Accepts between-contact and in-contact polarizing keys for precise alignment

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules
• Medical device circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm compatibility with required polarizing keys and flange characteristics. Ensure that the selected variant matches the intended PCB thickness range and mounting style requirements for the target application environment.

Edgeboard Connectors Selection Notes

Select this connector when a high-pin-count interface is necessary for dual-edge cards. Consider the 5 A current rating and operating temperature range of -40°C to +105°C for environmental suitability. Verify that the panel mount style aligns with the chassis design constraints.
