357-074-522-202

Edgeboard Connectors Overview

The EDAC Inc. 357-074-522-202 is a dual-edge card edge connector featuring 74 positions arranged in two rows of 37 contacts each. It utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The connector employs female half-beehive contacts with gold plating for reliable signal transmission. Designed for panel mount installation, it includes flanges with side openings and no threads. The housing is constructed from black thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 74 total contact positions for high-density interconnect applications
• Gold-plated half-beehive female contacts ensure stable electrical connection and corrosion resistance
• Panel-mount design with side-opening flanges facilitates secure mechanical attachment without threading
• Thermoplastic polyester insulation provides structural integrity within a wide operational temperature range

Edgeboard Connectors Applications

• High-density electronic circuit board interconnections requiring dual-edge access
• Industrial control systems utilizing standard card edge modules
• Medical equipment interfaces demanding reliable signal transmission
• Automotive electronics assemblies requiring robust panel-mounted connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, contact material, and flange specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status through current manufacturer certificates. Cross-reference ordering guides to validate availability and lead times directly with authorized distributors.

Edgeboard Connectors Selection Notes

Select this component when a 74-position dual-edge interface is required with a 3.96mm pitch. Verify that the application supports panel mounting with side-open flanges rather than surface mount or through-hole board edge options. Ensure the mating card thickness falls within the specified 0.054 to 0.070 inch range for proper contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 357 series of standard card edge connectors. The series offers various position counts and configurations tailored for diverse industrial and commercial applications. The 357 series is characterized by its use of half-beehive contacts and thermoplastic polyester housings, providing a balance of performance and cost-effectiveness for standard interconnect needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes indicating variations in flange style or contact finish. Consult the official EDAC ordering guide for cross-referencing equivalent components with matching mechanical dimensions and electrical ratings.
