305-052-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-208 is a standard card edge connector designed for vertical panel mounting applications. It features a dual-edge configuration with 52 positions arranged in two rows, providing a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Electrical specifications include a continuous current rating of 5 A and a dielectric withstand voltage of 1800 VAC rms. The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body made of green thermoplastic polyester
• Designed as a card extender with straddle mount installation style

Edgeboard Connectors Applications

• Vertical panel-mounted electronic assemblies
• Dual-edge card interface systems requiring polarizing key support
• Industrial control modules utilizing 0.062 inch thick PCBs

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact termination type and insulation color. Ensure the selected variant matches the required board thickness tolerance of 0.062 inches. Confirm RoHS compliance status directly with the manufacturer documentation prior to procurement. Cross-reference the Mouser or DigiKey part numbers to validate current availability and regional distribution restrictions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 52 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention via polarizing keys. Verify that the target PCB thickness falls within the specified range around 1.57 mm. Consider the 5 A current rating and 1800 VACrms dielectric strength for electrical safety margins in the design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent 0.156-inch pitch dimensions. The 305-052-555-208 specifically addresses needs for dual-edge interfaces with high reliability requirements in industrial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-052-520-201 and 305-052-556-278. Verify that alternative part numbers match the 52-position count and dual-edge configuration. Check for differences in termination style, such as solder lug versus solder pin, before substitution.
