302-050-656-201

Edgeboard Connectors Overview

The EDAC Inc. 302-050-656-201 is a dual-edge card edge connector from the 302 series, designed for board-to-board interconnection. It features 50 positions with a female contact type and a 0.050-inch (1.27mm) pitch spacing. The connector utilizes gold-plated contacts on a copper alloy base, housed in a black polyamide (PA66) insulator. It supports card thicknesses between 0.051 and 0.071 inches (1.30mm to 1.80mm). Rated for operation within a temperature range of -55°C to 85°C, it employs a solder termination method and is RoHS3 compliant.

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact finish and housing color specifications. Confirm compliance with RoHS3 directives for environmental regulations. Ensure the selected distributor provides valid traceability documentation. Cross-reference the manufacturer part number against official EDAC catalogs to avoid counterfeit components. Validate storage conditions to maintain moisture sensitivity level integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this component when a 1.27mm pitch dual-edge connection is required for compact designs. The cantilever contact style suits applications needing moderate mating cycles. Verify that the target PCB thickness falls within the 1.30mm to 1.80mm operational window. Consider the -55°C to 85°C temperature range for environmental suitability. Ensure the mounting style aligns with the mechanical constraints of the enclosure design.
