305-012-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-012-555-508 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 12 positions across two rows 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). Contacts are made of copper alloy with gold plating, rated for 5 A continuous current. The insulator body is green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts polarizing keys between contacts or within contact areas for secure board alignment
• Features a low-profile insulator body constructed from green thermoplastic material
• Utilizes half-beam contact type with gold plating for reliable electrical connection

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical card edge interface
• Systems utilizing polarized PCB designs for orientation control
• Industrial equipment operating within specified thermal ranges

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 12-position configuration and dual-row layout. Confirm compatibility with the target PCB thickness of 1.57 mm and verify that the mounting style aligns with the panel design requirements. Ensure environmental conditions fall within the stated operational temperature limits.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided edge cards. Consider the 3.96 mm pitch and 5 A current rating against system constraints. Evaluate the need for polarizing key acceptance if board orientation security is critical for the application.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series includes variants with different position counts and flange configurations. The 305-012-555-508 specifically denotes the 12-position variant with standard flange characteristics suitable for general-purpose panel mounting applications.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series parts for position count variations. Verify mechanical dimensions against existing enclosures. Check for equivalent products in the 315 or 355 series if flange or termination differences are acceptable.
