305-036-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-036-500-203 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features 36 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector accepts dual-edge cards with a thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure low contact resistance and durability. Rated for 5 A continuous current and 1800 VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing robust insulation and mechanical stability for PCB mounting applications.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Gold-plated contacts provide corrosion resistance and stable electrical performance
• Thermoplastic polyester insulation ensures high dielectric strength and thermal stability

Edgeboard Connectors Applications

• Industrial control system circuit boards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 36-position configuration and 1.57 mm board thickness tolerance. Confirm compliance with RoHS3 and REACH regulations as specified in the official datasheet. Ensure compatibility with existing polarizing key requirements if used in constrained spaces. Cross-reference the manufacturer's ordering guide to validate suffix codes against intended termination and material specifications before final procurement.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-edge connector is required for 1.57 mm thick PCBs. The 5 A current rating suits moderate power distribution needs. Verify that the operating environment stays within the -40°C to +105°C range. Consider the availability of polarizing keys if precise board insertion guidance is necessary for the assembly process.
