305-044-500-502

Edgeboard Connectors Overview

The EDAC Inc. 305-044-500-502 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 44 positions with a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes female half-bead contacts made of copper alloy with 10.0 µin gold plating. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic polyester, and it supports panel mount installation via solder lug termination.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Dual-edge female contact configuration ensures reliable signal transmission
• Thermoplastic polyester housing provides thermal stability and electrical insulation

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• High-voltage interface modules needing 1800 VACrms isolation
• Panel-mounted electronic assemblies with strict thermal requirements

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 44-position count and 3.96 mm pitch before ordering. Confirm compatibility with polarizing key types if mechanical locking is necessary for the application. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper contact engagement. Check RoHS compliance status against local regulatory requirements prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with high voltage rating is required. The 5 A current capacity suits moderate power distribution needs. Verify that the vertical panel mount style aligns with the enclosure design. Consider the half-bead contact type for its specific mating force characteristics compared to full-bead alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are standardized for industrial and commercial electronics. The series offers various position counts while maintaining consistent 3.96 mm pitch dimensions. The 305-044-500-502 variant specifically addresses applications requiring 44 connection points with robust environmental ratings.
