305-050-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-203 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 50 positions with a 3.96 mm (0.156 inch) contact spacing and two rows of contacts. The connector utilizes copper alloy terminals with gold plating and accepts printed circuit boards with a nominal thickness of 1.57 mm. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure board alignment
Features a low-profile insulator body constructed from thermoplastic material
Utilizes half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

Medical interconnect solutions requiring durable connections
Agricultural technology systems operating in harsh environments
Industrial control panels utilizing dual-edge card edge PCBs

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct flange characteristics and termination style. Confirm that the required polarizing key configuration matches the design intent, as these connectors accept both between-contact and in-contact keys. Cross-reference the thermal rating and current capacity with system requirements before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a 50-position dual-row interface is required for thick PCB applications up to 1.57 mm. Ensure the design accommodates the 3.96 mm pitch and vertical panel mounting constraints. Consider the need for polarizing keys if mechanical alignment stability is critical for the specific assembly environment.
