837-040-541-607

Edgeboard Connectors Overview

The EDAC Inc. 837-040-541-607 is a single-row, female card edge connector designed for through-hole mounting with wire wrap termination. It features 40 positions with a 0.156-inch (3.96mm) contact spacing and accepts cards ranging from 0.054 to 0.070 inches thick. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). The green insulator is constructed from Diallyl Phthalate (DAP), supporting an operating temperature range of -40°C to 125°C.

Edgeboard Connectors Feature Summary

• Utilizes cantilever spring contacts for reliable signal transmission
• Features a flush mount flange with top opening and no threads
• Constructed with durable DAP insulator material for thermal stability

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature reliability
• Telecommunications equipment interface connections
• Automotive electronics board-to-board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 837 Series Ordering Guide to ensure correct termination style and flange configuration. Confirm RoHS3 compliance status and REACH restrictions prior to final procurement decisions. Cross-reference the full part number with distributor catalogs to validate current availability and lead times.

Edgeboard Connectors Selection Notes

Select this component when a 40-position single-edge female connector is required for wire wrap applications. Ensure the PCB layout accommodates the 0.156-inch pitch and that the mating card thickness falls within the specified 0.054 to 0.070-inch range. Consider the high-temperature rating if the application environment exceeds standard commercial limits.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 837 High Temp series, which is engineered for demanding environments. The series offers various pin counts and termination options, all sharing consistent mechanical dimensions and material properties. The 837-040 variant specifically provides a balance of density and spacing suitable for complex circuit board architectures.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 837 Series Ordering Guide for direct substitutes. Verify compatibility regarding contact count, pitch, and termination method before considering alternative part numbers.
