857-062-459-202

Edgeboard Connectors Overview

The EDAC Inc. 857-062-459-202 is a standard card edge connector designed for dual-edge board applications. It features 62 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes copper alloy contacts with a tin finish and semi-bellows contact type. It supports wire wrap termination and is constructed from thermoplastic polyester housing. The unit is rated for operation between -40°C and +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified card types
• Semi-bellows contact type ensures reliable engagement with card edges
• Wire wrap termination method for secure circuit interconnection
• Flush mount flange feature with top opening for panel installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Consumer electronics internal board connections

Edgeboard Connectors Procurement Notes

Verify the specific contact finish requirement against application needs, as this part uses a tin finish rather than gold. Confirm that the 3.96 mm pitch aligns with the target card edge thickness and layout specifications. Ensure the wire wrap termination capability matches the available assembly tools and processes. Check RoHS compliance status if required by regional regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row configuration with a 3.96 mm pitch is required for vertical panel mounting. The tin-plated contacts offer a cost-effective solution for environments where high corrosion resistance is not critical. Consider the semi-bellows contact type for maintaining signal integrity during mating cycles. Evaluate the thermoplastic polyester housing durability against the expected operating temperature range of -40°C to +105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors. The series provides various position counts and row configurations for diverse board-to-board or board-to-panel applications. The 857 series typically features flush mount flanges and supports both single and dual-edge card interfaces. It is part of a broader portfolio offering robust interconnect solutions for industrial and commercial sectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different finishes or row configurations. Verify compatibility with existing tooling and panel cutouts when considering alternative part numbers from the same manufacturer family.
