857-056-560-201

Edgeboard Connectors Overview

The EDAC Inc. 857-056-560-201 is a standard card edge connector featuring 56 positions arranged in a dual female configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and a 0.200-inch (5.08 mm) row spacing. The component accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with gold-plated copper alloy contacts and a black thermoplastic insulator body, it offers high-profile insulation for robust mechanical stability.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating, row count, and mounting style match the design requirements. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-row connection is required for 56-position applications. Ensure the target PCB thickness aligns with the 0.062-inch specification. Consider the 0.156-inch pitch for trace routing density and verify that the high-profile housing fits within the available vertical clearance constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series, which specializes in high-temperature card edge connectors. The series is characterized by durable thermoplastic bodies and gold-plated contacts designed for demanding environments. It serves as a critical interface solution for connecting edge-mounted circuit boards in various electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 857 series designation, such as 857-056-560-208, provided they maintain identical pin counts and electrical specifications. Verify mechanical dimensions and termination methods before substitution.
