305-068-520-258

Edgeboard Connectors Overview

The EDAC 305-068-520-258 is a standard card edge connector featuring 68 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) pitch and accepts double-sided, unspecified card edge boards with thicknesses between 1.37 mm and 1.78 mm. The connector employs female half-bead contacts made of copper alloy with gold plating for reliable signal transmission. Designed for panel mount installation at a vertical angle, it supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The insulator is constructed from green thermoplastic polyester, ensuring stability across an operating 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 gold-plated copper alloy half-bead contacts for durable electrical connection
• Constructed with green thermoplastic polyester insulation for environmental stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standardized card edge modules
• Medical devices needing high dielectric strength connectors
• Energy sector hardware demanding reliable vertical panel integration

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure compatibility with required flange features and contact configurations. Confirm that the target application environment falls within the specified -40°C to 105°C operating temperature range. Check RoHS compliance status if restricted substances are a project constraint. Ensure the PCB card thickness aligns with the 1.37 mm to 1.78 mm acceptance window. Cross-reference the 4-40 threaded insert specifications if mechanical mounting details are critical for the enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 68-position interface is required for double-sided card edge applications. The 3.96 mm pitch accommodates standard board layouts while providing ample spacing for high-voltage isolation up to 1800 VACrms. Choose this model for panel-mount scenarios where vertical orientation and solder pin termination are preferred over surface mount alternatives. Consider the 5 A current rating for power distribution needs alongside signal integrity requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which specializes in standard card edge connectors designed for versatile industrial and commercial applications. The series offers various position counts and pitch options to suit different board densities. Components in this family typically feature robust metal housings or flanges for secure panel attachment. The 305 series emphasizes reliability through gold-plated contacts and stable thermoplastic insulation materials suitable for harsh environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but differing flange or contact variations. Verify that any alternative maintains the 3.96 mm pitch and 68-position configuration. Ensure replacement units support the same 5 A current rating and 1800 VACrms dielectric strength. Check compatibility with existing polarizing key requirements if mechanical locking is utilized in the assembly.
