305-018-521-507

Edgeboard Connectors Overview

The EDAC 305-018-521-507 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 18 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and accepts PCBs with a thickness of 1.57 mm. Rated for 5 A continuous current, it employs a solder lug termination method and 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 alignment
• Provides 1800VACrms dielectric voltage withstand capability
• Features gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connections
• Industrial control systems utilizing polarized card edge interfaces
• Equipment needing high dielectric strength interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 18-position configuration and 3.96 mm pitch before ordering. Confirm compatibility with polarizing key requirements if mechanical locking is necessary. Ensure the target PCB thickness aligns with the specified 1.57 mm dimension. Check regional availability as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount card edge connector with a 3.96 mm pitch is required. It is suitable for designs needing 18 signal paths with dual-row access. Consider the 5 A current rating and 105°C maximum operating temperature for thermal management. Verify that the solder lug termination style fits the assembly process constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm spacing. These connectors are engineered for robust panel mounting and support polarizing keys to prevent misalignment during insertion.

Edgeboard Connectors Replacement Considerations

Cross-reference other EDAC 305 series parts with identical 18-position counts and 3.96 mm pitch. Ensure replacement options maintain the same vertical panel mount orientation and solder lug termination type.
