306-027-420-112

Overview

The EDAC Inc. model 306-027-420-112 is a standard card edge connector from the 306 series, designed for panel mount vertical installation. It features a single row with 27 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The insulator body is made of thermoplastic material, providing structural integrity and electrical insulation. The unit operates within a temperature range of -40°C to +105°C and has an insulation resistance of 5 GOhms.

Feature Summary

• Vertical panel mount design for secure board integration
• Gold-plated copper alloy contacts for corrosion resistance
• Single centerline row configuration for simplified routing
• Thermoplastic insulator body for low profile structure

Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interfaces
