305-020-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-507 is a standard card edge connector featuring 20 positions with a 3.96 mm pitch. It utilizes a dual-side configuration for board insertion and employs a panel mount installation style at a straight angle. The contacts are constructed from copper alloy, offering a continuous current rating of 5 A. The unit operates within a temperature range of -40°C to +105°C and accepts between-contact or in-contact polarizing keys.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features gold plating on the mating area and tin plating on tails with nickel underplating
• Provides a 5A continuous current rating and 1800VACrms dielectric strength

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring standardized card edge interfaces
• Industrial control systems utilizing polarized connection methods
• Equipment operating within -40°C to +105°C environmental conditions

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 555-507 corresponds to the required plating configuration (gold mating/tin tail) and flange features. Confirm compatibility with polarizing key requirements if mechanical locking is necessary. Ensure the panel mounting hole pattern matches the M3 threaded insert specifications provided in the official datasheet before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a 20-position dual-side connector with a 3.96 mm pitch is required for panel mounting. It is suitable for applications needing robust polarization via between-contact or in-contact keys. Verify that the 5A current rating and thermal limits meet the system's electrical and environmental demands compared to other series variants.

Edgeboard Connectors Part Context
