305-038-520-278

Edgeboard Connectors Overview

The EDAC 305-038-520-278 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 38 positions with a 3.96 mm pitch and supports a board thickness of 1.57 mm. The connector utilizes two rows of gold-plated copper alloy contacts rated for 5 A current. It employs solder pin termination and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, providing an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Vertical panel mount installation style with through-hole solder termination
• Gold-plated copper alloy contacts ensure reliable electrical performance

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring card edge interface
• Industrial control systems utilizing standardized interconnects
• Equipment needing polarized keying for connection security

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact finish thickness and plating specifications. Ensure the selected variant matches the required polarizing key compatibility and thermal rating. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and compliance certifications such as RoHS before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount card edge solution with 38 positions is required. The 3.96 mm pitch accommodates standard double-sided boards of specified thickness. Consider the 5 A current rating and operating temperature range for environmental suitability. Verify that the application design allows for the necessary polarizing key integration to prevent misalignment during mating.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing and robust construction. These connectors are engineered for high-reliability connections in demanding environments, featuring durable thermoplastic housings and precise contact geometry for stable signal transmission.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 38-position configurations and identical 3.96 mm pitch specifications. Ensure replacement parts maintain the same vertical panel mount orientation and solder pin termination type. Verify that alternative models support the required polarizing key options and meet the same electrical ratings.
