305-052-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-578 is a dual-row card edge connector designed for panel mount applications. It features 52 positions with a contact spacing of 3.96 mm and a row spacing of 3.56 mm. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are made of copper alloy with gold plating, providing a continuous current rating of 5 A and an insulation resistance voltage of 1800 VACrms. The insulator body is green thermoplastic polyester, rated for operation between -40°C and 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with half-beamlock contacts for secure board retention
• Accepts both between-contact and in-contact polarizing keys for alignment
• Low-profile insulator body constructed from green thermoplastic polyester
• Panel mount design with flange features including top opening and threaded inserts

Edgeboard Connectors Applications

• Medical interconnect solutions requiring reliable signal transmission
• Agricultural technology equipment operating in harsh environments
• Industrial control systems utilizing standard card edge interfaces
• General electronic assemblies requiring high insulation voltage ratings

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting hardware and keying options. Confirm that the target PCB thickness falls within the specified acceptance range of 1.37 mm to 1.78 mm. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the selected variant matches the required contact plating thickness and material specifications for the intended electrical load.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required for panel-mounted installations. Consider the 5 A current rating and 1800 VACrms insulation capability for appropriate electrical isolation needs. Evaluate the need for polarizing key compatibility if precise board insertion alignment is critical. Verify that the green thermoplastic polyester housing meets the thermal and mechanical requirements of the application environment.

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 robust construction and suitability for demanding industrial and medical applications. Similar parts in the series may differ in position count, such as 50 or 52 positions, or mounting style variations. The 305-052-521-578 specifically denotes the 52-position dual-row variant with gold-plated contacts.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row spacing but different position counts, such as 305-050-520-578. Verify mechanical fit and electrical ratings before swapping. Parts with different suffixes may alter mounting features or keying options without changing the core connector function. Always cross-reference datasheets to confirm compatibility with existing PCB layouts and enclosure constraints.
