305-040-521-508

Edgeboard Connectors Overview

The EDAC 305-040-521-508 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 40 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The unit provides a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density board connections
• Gold-plated copper alloy contacts for corrosion resistance and conductivity
• Panel-mount design with vertical installation angle for structural stability
• Thermoplastic insulator body compatible with specified PCB thicknesses

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and insulation color variants. Ensure that the target application PCB thickness aligns with the connector's acceptance range. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, vertically mounted card edge interface is required for systems demanding 5 A current capacity. The 3.96 mm pitch suits applications where board space allows for wider spacing compared to finer pitches. Verify that the panel cutout dimensions accommodate the flange specifications and that the mating card edge meets the mechanical tolerances defined in the datasheet.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for durability in demanding environments. The series offers various position counts and termination options, providing flexibility for different board densities. The 305-040 variant specifically addresses requirements for 40-position interfaces, balancing connectivity density with mechanical strength.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 40-position count and 3.96 mm pitch. Verify compatibility with existing panel mounts and PCB stack-ups. Ensure that any substitute maintains the same current rating and temperature operating range to preserve system reliability.
