305-032-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-032-555-503 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features a 32-position configuration with a 3.96 mm (0.156 inch) pitch. The connector supports a maximum PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A continuous current, it employs a solder lug termination method and is housed in green thermoplastic polyester insulation. This panel-mount component operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure card edge insertion
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Panel mount installation style with vertical orientation
• Compatible with between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement instruments needing high-reliability signal paths
• Automotive electronics modules with strict environmental tolerance requirements

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 503 corresponds to the required termination type and housing color before ordering. Confirm compatibility with the target PCB thickness of 1.57 mm and ensure the mounting panel allows for the specified vertical orientation. Cross-reference the 32-position count against the design schematic to prevent pinout mismatches. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with a 3.96 mm pitch is required for panel mounting. The 5 A current rating suits moderate power distribution needs. Consider the gold plating for environments where oxidation resistance is critical. Ensure the application does not require straight mounting or different PCB thicknesses, as these variants exist within the same series but differ mechanically.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, including PCB mount and panel mount configurations. The 305 series is characterized by its durable thermoplastic polyester housing and consistent 3.96 mm pitch, providing a standardized solution for industrial interconnect applications across multiple product lines.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers such as 305-032-555-203 and 305-032-555-512, which share the same 32-position count and 3.96 mm pitch. Verify that alternative suffixes match the required termination style and housing color specifications before substitution.
