305-016-520-568

Edgeboard Connectors Overview

The EDAC Inc. 305-016-520-568 is a standard card edge connector from the 305 series, designed for dual-edge female connections with 16 positions. It features a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054 to 0.070 inches). The connector utilizes copper alloy contacts with gold plating and employs a solder pin termination type for panel mounting. It operates within a temperature range of -40°C to +105°C and supports a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Utilizes half-beam contact type for reliable electrical connection

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card interface
• Industrial control systems operating in extreme temperature environments
• High-reliability data transmission modules using polarized keying

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct contact plating thickness and insulation material specifications. Confirm that the required polarizing key configuration matches the intended application constraints before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 16 positions and 3.96 mm spacing is required for panel installation. Ensure the host PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Consider the 5 A current rating and -40°C to +105°C operating temperature window for environmental compatibility.
