315-074-555-268

Edgeboard Connectors Overview

The EDAC Inc. 315-074-555-268 is a dual-edge female card edge connector from the 315 series, designed for board-edge mounting. It features 74 positions with a 0.156-inch (3.96mm) contact spacing and two rows of contacts. The connector utilizes gold-plated half-crimped terminals on copper alloy substrates, ensuring reliable signal transmission. It accommodates printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The housing is constructed from green thermoplastic polyester, providing durability across an operating temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated half-crimped terminals for enhanced conductivity
• Thermoplastic polyester insulation for thermal stability
• Panel-mount flange design with threaded inserts

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device internal circuit connections
• Energy sector instrumentation modules

Edgeboard Connectors Procurement Notes

Verify that the replacement PCB thickness falls within the specified 0.054 to 0.070-inch range to ensure proper mechanical engagement. Confirm that the mating card edge does not exceed the connector's current rating limits. Check for RoHS3 compliance requirements if environmental regulations apply to the final assembly. Ensure mounting hardware matches the 4-40 thread specification for secure installation.

Edgeboard Connectors Selection Notes

Select this component when a robust panel-mount solution is required for high-density signal routing. The 0.156-inch pitch offers a balance between pin count and spacing reliability. Consider the threaded flange feature if vibration resistance and secure panel attachment are critical priorities over surface-mount alternatives. Evaluate the operating temperature range against the specific environmental conditions of the target application.
