305-032-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-258 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 32 positions with a 0.156-inch (3.96 mm) pitch and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The connector utilizes female contacts made of copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current, it supports vertical panel mounting via solder lug termination. The insulator body is constructed from thermoplastic material, providing structural integrity within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact assembly requirements
• Includes integrated card guides to facilitate precise insertion and retention

Edgeboard Connectors Applications

• Panel-mounted interface connections
• Card extender systems
• Edgeboard interconnects requiring polarizing key compatibility

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required contact configuration and termination style. Confirm that the polarizing key options are compatible with your system design. Ensure the PCB thickness falls within the specified acceptance range. Check for RoHS compliance status if environmental regulations apply to your project. Validate the current rating against your application's electrical load requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with polarizing key capability is required. The 32-position count suits moderate-density interconnect needs. The 5A rating supports standard industrial signal and power loads. Consider the straddle mount or panel mount installation style based on chassis constraints. Verify that the 3.96mm pitch aligns with the target PCB trace layout.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its robust construction for repeated mating cycles. Similar parts in the series vary primarily by position count and termination type, sharing common mechanical dimensions and electrical ratings.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 32 positions and dual-edge configuration. Cross-referencing with identical pitch and current ratings is essential. Verify that any alternative maintains the same polarizing key acceptance and mounting style.
