305-048-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-202 is a standard card edge connector from the 305 series, designed for panel mounting with vertical orientation. It features 48 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator body is constructed from thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-row header design with low-profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel mount installation style with vertical orientation
• Accepts standard 0.062 inch nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computer peripheral interface connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required board thickness and contact termination type. Confirm that the 48-position dual-row configuration matches the target PCB layout dimensions. Check RoHS compliance status if environmental regulations apply to the end product assembly process.

Edgeboard Connectors Selection Notes

Select this component when a high-density 48-pin interface is required for vertical panel mounting. The 3.96 mm pitch accommodates standard double-sided card edge designs. Ensure the application environment stays within the specified operating temperature range of -40°C to +105°C for optimal performance and longevity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and configurations for card edge applications. The series is characterized by its durable construction and standardized dimensions, facilitating integration into modular electronic systems where reliable mechanical and electrical connections are critical for long-term operation.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-040-521-202 or 305-054-556-278 for different pin counts. Verify that any substitute maintains the same 3.96 mm pitch and 0.062 inch board thickness acceptance to ensure mechanical fit without redesigning the host PCB.
