305-044-520-268

Edgeboard Connectors Overview

The EDAC 305-044-520-268 is a standard card edge connector from the 305 series, featuring 44 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for 1.57 mm nominal thickness printed circuit boards. The connector employs gold-over-nickel plating on copper alloy contacts to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it supports panel mount installation with vertical orientation. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low profile insulator body constructed from thermoplastic polyester
• Provides robust electrical performance with high insulation resistance and voltage rating

Edgeboard Connectors Applications

• Industrial control systems requiring secure card edge connections
• Telecommunications equipment utilizing standardized board interfaces
• Test and measurement devices needing reliable vertical panel mounting

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, row configuration, and termination type. Ensure compatibility with target PCB thickness and polarizing key requirements. Cross-reference RoHS compliance status with current regulatory standards before procurement. Confirm availability through authorized distributors as supply levels may vary.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 44 positions is required for vertical panel mounting. Ensure the application environment stays within the specified temperature range of -40°C to +105°C. Verify that the mating card edge board meets the 1.57 mm thickness specification. Consider the 3.96 mm pitch for layout constraints and check if polarizing key integration is necessary for the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its 3.96 mm pitch and dual-row configuration. Similar parts in the family include different position counts such as 305-040 or 305-048, maintaining consistent electrical ratings and mechanical dimensions for interchangeability within system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include EDAC 305-040-520-268 and 305-048-520-268, provided the position count difference is acceptable. Verify mechanical fit and electrical ratings match the original design requirements before substitution.
