305-016-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-016-521-558 is a dual-edge female card edge connector from the 305 Series, designed for through-hole mounting. It features 16 positions with a 0.156-inch (3.96mm) contact spacing and half-beam contact type. The connector utilizes gold-plated copper alloy contacts with a 10.0µin thickness to ensure reliable signal transmission. It accepts printed circuit boards with a thickness range of 0.054 to 0.070 inches (1.37mm to 1.78mm). The insulator body is made of green thermoplastic polyester, supporting an operating temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with half-beam contacts for secure board retention
