305-034-556-503

Edgeboard Connectors Overview

The EDAC Inc. model 305-034-556-503 is a standard card edge connector featuring a dual female configuration with 34 positions. It utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. Designed for panel mounting in a vertical orientation, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable conductivity. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40 C to +105 C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with gold-plated copper alloy contacts
• Accepts between-contact and in-contact polarizing keys
• Vertical panel mount design compatible with 1.57 mm PCB thickness

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and pitch before ordering. Confirm that the receiving board thickness aligns with the 1.57 mm specification. Ensure that the application environment remains within the stated temperature limits. Check for any specific polarizing key requirements if signal isolation is necessary. Validate that the gold plating meets the corrosion resistance needs of the intended deployment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection is required for a 34-position interface. The 3.96 mm pitch suits applications where space allows for wider spacing compared to finer pitches. Consider the vertical panel mount style for chassis-based installations. The 5 A rating supports moderate power distribution alongside signal transmission. Verify compatibility with existing polarizing key systems if used in high-reliability environments.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized card edge solutions. The series offers various position counts and mounting styles to accommodate different board densities. The 305 series is designed for robust mechanical retention and electrical stability in demanding industrial settings. It complements other components in modular electronic systems requiring secure card insertion.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 34-position count, 3.96 mm pitch, and dual-row female configuration. Verify that alternative parts support the same 1.57 mm PCB thickness and vertical panel mounting. Ensure equivalent current ratings and insulation voltage specifications are met. Cross-reference polarizing key compatibility if the original design relies on specific keying mechanisms.
