305-032-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-032-521-268 is a standard card edge connector header from the 305 series, designed for panel mount and through-hole installation. It features 32 positions with a dual-edge configuration and a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating, rated for 5 A continuous current. The housing is green thermoplastic, accommodating board thicknesses of 1.37 mm to 1.78 mm. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides 1800VACrms dielectric withstand voltage capability
• Features solder lug termination for reliable panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• Telecommunications equipment interfaces
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact contact plating thickness and insulation material variations. Ensure compatibility with existing polarizing key requirements before procurement. Cross-reference the 32-position count and 3.96 mm pitch with system design specifications to prevent interface mismatches during integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with polarizing key acceptance is required. The 5 A rating and 1800VACrms insulation support high-reliability applications. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm range for proper mechanical engagement and electrical performance.
