306-031-521-178

Overview

The EDAC Inc. 306-031-521-178 is a dual female card edge connector featuring 62 positions arranged in two rows. It utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component employs gold-plated contacts for reliable signal transmission and is housed in a low-profile insulator body. Designed for panel mounting, it supports vertical installation angles and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female configuration providing 62 connection points across two rows
• Gold-plated contacts ensure durable electrical performance
• Low-profile insulator body design facilitates compact assembly
• Compatible with standard 0.062-inch nominal thickness PCBs

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics board-to-board connections
