305-018-500-212

Edgeboard Connectors Overview

The EDAC Inc. 305-018-500-212 is a standard card edge connector from the 305 Series, designed for vertical panel mount applications. It features 18 positions with a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. Constructed with a thermoplastic polyester insulator body, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact installation requirements
• Provides high insulation resistance of 5 GOhms for electrical safety

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized module connections
• Test and measurement devices needing reliable vertical mounting solutions

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Cross-reference the Mouser or DigiKey part numbers with the original datasheet to avoid substitution errors during acquisition.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 18 positions is required for vertical panel mounting. The 3.96 mm pitch accommodates standard board layouts while the 5 A rating suits moderate power applications. Consider the polarizing key acceptance feature if precise board orientation is critical. Verify that the thermoplastic polyester housing meets the thermal and chemical resistance requirements of the intended operating environment.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 Series, a line of standard card edge connectors known for their durability and versatility. The series offers various position counts and termination styles to suit different design needs. The 305-018-500-212 specifically addresses applications requiring a 18-position interface with gold-plated contacts and a green insulator body, fitting within the broader category of industrial-grade interconnect solutions.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination types. Verify mechanical dimensions and electrical ratings before replacing with generic equivalents. No specific public substitute part numbers are confirmed for this exact configuration.
