305-056-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-507 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 56 positions arranged in a dual row configuration with a pitch of 3.96 mm (0.156 inches). The connector supports a PCB thickness of 1.57 mm and utilizes gold plating on the mating area to ensure reliable signal transmission. It has a continuous current rating of 5 A and offers high insulation resistance of 5 GOhms. The unit operates within a temperature range of -40°C to +105°C and accepts between-contact and in-contact polarizing keys.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features gold plating on the mating area for enhanced conductivity
• Supports dual-row configuration for high-density connections

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical card edge connection
• Industrial control systems utilizing polarized keying for safety
• High-reliability data acquisition hardware

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 56-position count and dual-row layout. Confirm compatibility with the target PCB thickness of 1.57 mm before integration. Ensure that the design accommodates the necessary polarizing keys if between-contact or in-contact types are specified. Cross-reference the voltage rating requirements against the component's 1800VACrms capability to guarantee operational safety under expected load conditions.

Edgeboard Connectors Selection Notes

Select this component when a robust, vertically mounted solution is needed for double-sided edge cards. The 3.96 mm pitch provides ample spacing for high-voltage isolation compared to finer pitches. Consider the thermal stability up to 105°C for environments with significant heat generation. The copper alloy contacts with gold finish offer durability for repeated insertion cycles typical in modular system architectures.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for industrial and commercial applications. The series is characterized by its versatility in position counts and row configurations. The 305-056 variant specifically addresses needs for moderate-to-high pin counts while maintaining a standardized footprint compatible with existing panel designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 56-position dual-row variants such as 305-056-556-507, provided the termination style matches the assembly requirements. Verify that any alternative maintains the identical 3.96 mm pitch and 1.57 mm board thickness tolerance to ensure mechanical fit.
