305-042-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-503 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 42 positions arranged in a dual row configuration with a 0.156-inch (3.96 mm) pitch. The connector utilizes female contacts made of copper alloy with gold plating and employs a solder lug termination type. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material, and it accommodates board thicknesses between 0.054 inches and 0.070 inches.
