305-032-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-032-521-503 is a standard card edge connector from the 305 Series, designed for dual-sided board insertion. It features 32 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and a solder termination method for secure electrical connections. Constructed with a green thermoplastic insulator, it is rated for 5 A current and operates within a temperature range of -40°C to +105°C.
