833-042-521-602

Edgeboard Connectors Overview

The EDAC Inc. 833-042-521-602 is a standard card edge connector from the 833 series, designed for single-edge board applications. It features 42 positions with a 0.156-inch (3.96 mm) pitch and supports PCB thicknesses of 0.054 to 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated cantilever contacts with a 10.0µin finish for corrosion resistance and reliable signal transmission. Constructed with a green diallyl phthalate (DAP) housing, it offers vertical panel mount installation. The unit is rated for 3A current and operates within a temperature range of -55°C to +125°C.

Edgeboard Connectors Feature Summary

• Gold-plated cantilever contact design ensures low insertion force and high durability for repeated mating cycles.
• Vertical panel mount configuration provides secure mechanical stability in enclosed chassis environments.
• Green Diallyl Phthalate (DAP) insulator housing delivers robust thermal resistance and electrical insulation properties.

Edgeboard Connectors Applications

• Industrial control systems requiring reliable I/O connections
• Medical equipment interconnect solutions
• Automotive electronics modules
• Telecommunications infrastructure hardware

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact finish and housing color specifications. Confirm the PCB thickness tolerance aligns with your board manufacturing capabilities to ensure proper retention. Check regional availability as distribution may be limited in certain areas. Ensure compliance with RoHS directives if applicable to your assembly process. Validate pin count and pitch requirements against the target circuit board layout before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a single-edge card interface with 42 positions is required. The 0.156-inch pitch suits applications needing moderate density without excessive miniaturization. Choose the vertical panel mount style for fixed installations where space constraints favor height over depth. The gold contact finish is appropriate for environments demanding long-term corrosion resistance. Consider the DAP material for superior heat dissipation compared to standard thermoplastics.

Edgeboard Connectors Part Context

This part belongs to the EDAC 833 series, a line of standard card edge connectors engineered for general-purpose and specialized industrial uses. The series emphasizes mechanical reliability and consistent electrical performance across various environmental conditions. Components in this family are widely utilized in sectors such as medical technology and agricultural machinery, where durable interconnects are critical for system longevity and operational safety.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 833 series variants with matching position counts and pitch dimensions. Cross-reference compatible parts from the same manufacturer to maintain consistent mounting hole patterns and housing profiles. Verify that alternative options retain the same cantilever contact mechanism and gold plating specifications to ensure functional equivalence in existing designs.
