305-050-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-507 is a dual-edge female card edge connector with 50 positions arranged in two rows of 25 contacts. It features a 0.156-inch (3.96mm) contact spacing and accepts PCBs with thicknesses between 0.054 and 0.070 inches (1.37mm to 1.78mm). The connector utilizes gold-plated copper alloy half-bellows contacts for reliable signal transmission. Designed for panel mount through-hole installation, it includes M3 threaded inserts for secure mounting. The insulator body is constructed from green thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to 105°C.

• Test and measurement instrumentation with specific form factor constraints

Edgeboard Connectors Procurement Notes

Verify the exact part number against manufacturer documentation to confirm compatibility with specific PCB thickness requirements within the 0.054 to 0.070 inch range. Ensure that the mounting environment supports the specified operating temperature range of -40°C to 105°C. Confirm that the M3 threaded insert dimensions align with the assembly hardware specifications. Cross-reference the RoHS compliance status with current regulatory standards applicable to the target market before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 50 positions is required for panel-mounted applications. The 0.156-inch pitch and specific PCB thickness tolerance are critical selection factors. Consider the gold plating and half-bellows contact design for environments demanding high reliability and low contact resistance. Verify that the thermoplastic polyester material meets the thermal and chemical resistance needs of the application environment.
