857-006-454-101

Edgeboard Connectors Overview

The EDAC Inc. 857-006-454-101 is a standard card edge connector receptacle featuring 12 positions with a 3.96 mm (0.156 inch) pitch. Designed for dual-edge non-specified cards, it utilizes semi-bellows female contacts finished with tin plating to ensure reliable signal transmission. The housing is constructed from black polyphenylene sulfide (PPS), providing durability and thermal stability across an operating temperature range of -40°C to +125°C. This panel mount component supports board thicknesses between 1.37 mm and 1.78 mm, offering a robust mechanical interface for high-density interconnect applications requiring secure mating cycles.

Edgeboard Connectors Feature Summary

• Dual-edge semi-bellows contact design ensures consistent force and reliable engagement with card edge profiles.
• Tin-plated copper alloy contacts provide corrosion resistance and stable electrical conductivity.
• Black PPS insulation material offers high thermal stability and mechanical strength for demanding environments.

Edgeboard Connectors Applications

• Industrial control systems requiring durable panel-mounted interfaces
• Communication equipment utilizing standard card edge modules
• Consumer electronics assemblies needing reliable high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific pin configuration and contact finish against project requirements before ordering. Confirm that the target PCB or card edge thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical fit. Check for any recent product change notifications regarding material composition or manufacturing origin. Ensure compatibility with existing panel mounting hardware and soldering processes used in the assembly line.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel mounting. The tin-plated semi-bellows contacts are suitable for applications where moderate current carrying capacity and frequent insertion cycles are expected. Consider the black PPS housing for its inherent flame retardancy and heat resistance. Evaluate the 12-position count against signal routing needs to determine if additional connectors are necessary for complex designs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and contact finishes to suit different application densities. The 857-006-454-101 specifically addresses the need for a 12-position dual-edge solution with tin plating, fitting into the broader portfolio of high-reliability interconnects provided by EDAC Inc. for diverse electronic assembly challenges.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other 12-position dual-edge connectors with identical 3.96 mm pitch and panel mount style. Verify that alternative components support the same board thickness range and offer comparable thermal ratings. Contact finish variations, such as gold versus tin, may affect long-term reliability in corrosive environments. Ensure mechanical dimensions match exactly to avoid PCB layout modifications during replacement.
