305-032-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-504 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 and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-bead contact type to ensure reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing insulation resistance of 5 GOhms. Designed for panel mounting at a vertical angle, it accommodates PCB thicknesses between 1.37 mm and 1.78 mm (0.054" to 0.070").

Edgeboard Connectors Feature Summary

• Dual-row female connector design specifically engineered for non-specified dual-edge card applications.
• Gold-plated copper alloy half-bead contacts provide durable electrical connections and corrosion resistance.
• Thermoplastic polyester insulation ensures high dielectric strength and stable performance across wide temperature ranges.
• Vertical panel mounting style with flush mount flange features for secure structural integration.

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interconnects.
• Telecommunications equipment utilizing modular board architectures.
• Test and measurement instruments needing reliable high-density connections.
• Automotive electronics modules demanding vibration-resistant connectors.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required dual-edge specification and pitch dimensions before procurement. Confirm that the supplier provides original manufacturer documentation to ensure compliance with RoHS3 standards. Check for any regional distribution restrictions or availability constraints that may affect supply chain continuity. Ensure storage conditions maintain component integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 3.96 mm pitch connector is required for dual-edge boards. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Evaluate the vertical panel mounting requirement against available chassis space. Compare alternative series if different flange features or contact materials are needed for specific mechanical constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various positioning options and mounting styles for card edge applications. The series is characterized by its standardized 3.96 mm pitch and robust construction suitable for industrial environments. Similar models in the series vary primarily by position count and specific mounting configurations, allowing for scalable design solutions within the same connector family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 Series variants for equivalent pitch and row configurations. Verify compatibility with existing PCB layouts and mounting hardware when substituting similar components. Ensure that any replacement maintains the same current rating and temperature specifications to preserve system reliability.
