305-046-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-046-520-201 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 46 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-beam contact type, rated for 5 A current. It is constructed with a thermoplastic polyester housing and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The unit employs through-hole solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness and housing color specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Confirm RoHS compliance status via the latest datasheet as regulatory requirements may vary by production batch.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge configuration with a 3.96 mm pitch is required for high-reliability connections. The 46-position count suits moderate-density applications. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Verify that the through-hole solder pin style aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles, providing a standardized solution for connecting edge-board modules to host systems.
