305-044-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-503 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 44 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a solder lug termination type. It accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and supports a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides reliable electrical connection through gold-plated copper alloy contacts

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement instrumentation needing polarized connector options

Edgeboard Connectors Procurement Notes

Verify that the specific order matches the full part number 305-044-520-503 to ensure correct position count and termination style. Confirm compatibility with the target PCB thickness of 1.57 mm before integration. Check RoHS compliance status if required by project specifications. Ensure that the panel mounting requirements align with the vertical installation angle specified for this component.

Edgeboard Connectors Selection Notes

Select this model when a 44-position dual-row interface is required for panels. The 3.96 mm pitch suits applications where standard board dimensions are utilized. Consider the polarizing key acceptance feature if mechanical stability against misalignment is critical. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles while maintaining consistent dimensional standards. The 305 series is widely used in industrial and commercial electronics for its durability and standardized form factor. This specific variant provides a balanced solution for medium-density interconnect needs.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-044-520-201 and 305-044-520-502. These alternatives share identical positioning and spacing but may differ in termination type or plating finish. Verify that any replacement maintains the 1.57 mm board thickness tolerance and panel mount capability.
