305-074-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-074-521-201 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 74 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts gold-plated for conductivity, it utilizes a thermoplastic polyester insulator body. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating specifications, and mounting style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the vertical panel mount configuration aligns with the mechanical assembly requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 74-position interface. The 3.96 mm pitch suits applications needing wider spacing between traces. Verify that the operating environment stays within the -40°C to +105°C range. Consider the thermoplastic polyester housing for general-purpose insulation needs in standard industrial environments.

Edgeboard Connectors Part Context
