305-074-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-268 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 74 positions arranged in two rows with 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). Contacts are made of copper alloy with gold plating and utilize a solder pin termination type. The insulator body is green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Low profile insulator body design suitable for space-constrained panel installations.
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance.
• Vertical panel mount configuration provides secure structural support for dual-edge cards.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board interconnects
• Communication equipment utilizing standard double-sided card edges
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify that the target application utilizes double-sided card edge PCBs compatible with the specified 0.062-inch nominal thickness. Confirm that the mounting environment remains within the operational temperature range of -40°C to +105°C. Ensure panel cutouts accommodate the specific flange dimensions and vertical alignment requirements of this series connector.

Edgeboard Connectors Selection Notes

Select this component when a high-density 74-position interface is required with a 3.96 mm pitch. This model is appropriate for designs necessitating vertical panel mounting rather than board-mounted headers. Consider the 305 series specifications if lower profile or different row spacing options are needed for alternative mechanical constraints.

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 mounting styles, providing a standardized solution for connecting double-sided circuit boards to backplanes or chassis panels through reliable soldered interfaces.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same family include 305-070-555-268 and 305-080-555-268, which share identical mechanical and electrical characteristics but differ in position count. Verify that any replacement maintains the 0.156-inch pitch and vertical panel mount configuration.
