845-102-540-802

Edgeboard Connectors Overview

The EDAC Inc. 845-102-540-802 is a high-temperature card edge connector from the 845 Series, designed for single-sided board applications. It features 102 positions with a 0.100-inch (2.54mm) pitch and utilizes female contacts. The component employs a gold-plated contact finish over a copper alloy base to ensure reliable signal transmission. Constructed with green diallyl phthalate (DAP) insulation, it supports panel mounting in a vertical orientation. The connector accommodates card thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 125°C.

Edgeboard Connectors Feature Summary

• High-temperature DAP insulator construction for thermal stability
• Gold-plated cantilever spring contacts for secure connection
• Vertical panel mount design with top opening flange

Edgeboard Connectors Applications

• Industrial control systems requiring high thermal resistance
• Military and aerospace electronic assemblies
• High-reliability communication equipment

Edgeboard Connectors Procurement Notes

Verify that the specific suffix '802' corresponds to the required termination style and mounting configuration, as variations exist within the 845 series. Confirm compliance with RoHS3 standards if environmental regulations apply. Ensure the ordering quantity aligns with manufacturer minimums and lead times, as availability may vary. Cross-reference the datasheet drawing to validate physical dimensions against the PCB layout requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this model when a high-density, single-sided interface is required for environments exceeding standard temperature limits. The 102-position count suits complex data or power distribution needs. Verify that the 0.100-inch pitch matches the target card edge specifications. Consider the vertical mounting profile and flange diameter to ensure adequate clearance within the enclosure design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 845 Series, which specializes in high-temperature card edge connectors. The series offers various configurations including different row counts, termination types, and mounting options. The 845-102-540-802 variant specifically addresses high-pin-count applications requiring robust performance under thermal stress, distinguishing it from lower-temperature or lower-density alternatives in the broader connector portfolio.
