305-016-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-016-520-502 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 16 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. Constructed with copper alloy contacts finished with gold plating, it supports a continuous current rating of 5 A. The housing is made of green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features half-beam contact type for robust signal transmission
• Includes flange characteristics with top opening for flush installation

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring card edge interfacing
• Industrial control systems utilizing standardized connector pitches
• Equipment needing polarized keying for correct board insertion

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 16-position count and dual-row configuration. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment falls within the specified -40°C to +105°C operating temperature limits. Check for any specific polarizing key requirements if mechanical locking is necessary for the assembly.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch card edge interface is required for panel-mount designs. The dual female configuration allows for mating with corresponding male headers or card edges. Consider the gold-plated copper alloy contacts for corrosion resistance and conductivity. The thermoplastic polyester housing provides durability for industrial environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations to suit different connectivity needs. The 305-016-520-502 specifically addresses applications requiring a 16-position dual-row interface with panel-mount capabilities.

Edgeboard Connectors Replacement Considerations

Consult official EDAC documentation for direct substitutes within the 305 series. Verify that alternative parts maintain the same 3.96 mm pitch and 16-position count. Ensure mechanical dimensions and flange specifications match the existing panel cutouts.
