857-082-455-212

Edgeboard Connectors Overview

The EDAC Inc. 857-082-455-212 is a standard card edge connector receptacle featuring 82 positions arranged in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 5.08 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A per contact. The housing is constructed from black polyphenylene sulfide, and contacts are tin-plated copper alloy. It supports vertical panel mount installation.

Edgeboard Connectors Feature Summary

• Dual edge female contact configuration for secure board insertion
• Low profile insulator body design for compact assembly
• Vertical panel mount orientation for fixed positioning
• High temperature resistant polyphenylene sulfide housing

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature reliability
• Telecommunications equipment interface connections
• Automotive electronic module interconnects
• Test and measurement instrument backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm plating type and material composition. Ensure the selected variant matches the required contact spacing and board thickness specifications for your application. Confirm RoHS compliance status if restricted substances are prohibited in your manufacturing process. Cross-reference the part number with the latest EDAC Inc. documentation to avoid discrepancies between legacy and updated product lines.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for 0.062-inch thick PCBs. The 3.96 mm pitch suits applications needing robust mechanical retention without fine-pitch density. Consider the tin plating for general-purpose use where gold plating is not strictly necessary. Verify that the vertical mounting style aligns with the chassis or panel layout constraints of the final assembly design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors. The series offers various position counts and row configurations to accommodate different signal routing needs. The 857 series is designed for high-reliability environments, utilizing durable thermoplastic materials. It provides a standardized solution for connecting edge-mounted circuit boards to system infrastructure.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical 82-position dual female configurations and matching 3.96 mm spacing. Verify mechanical dimensions and electrical ratings before swapping. Alternative manufacturers may offer similar form-factor connectors, but pin compatibility and mounting hole patterns must be validated.
