305-024-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-024-521-203 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 24 positions across two rows, utilizing a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts that are gold-plated, it supports a continuous current rating of 5 A and withstands 1800 VACrms. The insulator body is made of green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact configuration details. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm RoHS compliance status matches project regulatory requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 24 positions is required for panel-mounted vertical installations. The 3.96 mm pitch suits applications needing wider spacing for high-voltage isolation or ease of assembly. Consider the 5 A current rating and 1800 VACrms dielectric strength for power and signal integrity needs. Verify that the polarizing key acceptance feature aligns with the mechanical design constraints of the enclosure.

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 configurations to support diverse interface requirements.
