305-078-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-268 is a standard card edge connector featuring 78 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a row spacing of 3.56 mm (0.140 inch). Designed for panel mount installation at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. This component operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, termination type, and insulator material. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the RoHS status and environmental compliance requirements with project specifications. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure constraints.

Edgeboard Connectors Selection Notes

Select this model when a 78-position dual-row interface is required with a 3.96 mm pitch. The vertical panel mount style is suitable for chassis-mounted applications where space efficiency is critical. Verify that the operating temperature range of -40°C to +105°C meets the environmental conditions of the deployment site. Ensure the gold-plated contacts satisfy the conductivity and durability requirements of the application.

Edgeboard Connectors Part Context
