305-040-500-512

Edgeboard Connectors Overview

The EDAC 305-040-500-512 is a standard card edge connector from the 305 series, designed for dual-edge PCB insertion. It features 40 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are made of copper alloy with gold plating, supporting a continuous current rating of 5 A. The housing is constructed from green thermoplastic polyester, providing an insulating resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarization keys and mounting styles. Confirm that the thermal and electrical ratings align with the target application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with 40 positions and 3.96 mm pitch is required. Ensure the host PCB thickness matches the specified 1.57 mm tolerance. Consider the need for polarizing keys if mechanical locking is necessary for the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations, maintaining consistent 3.96 mm spacing across models. The 305-040-500-512 specifically denotes the 40-position variant with gold-plated contacts and a green thermoplastic housing.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 3.96 mm pitch and 40-position count. Verify mechanical dimensions and electrical ratings match exactly before substituting.
