305-046-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-512 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a dual row configuration providing 46 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, while the insulator body is made of thermoplastic material. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 46-position dual row configuration before procurement. Confirm that the receiving system supports the specified 3.96 mm pitch and 1.57 mm board thickness. Ensure compatibility with the vertical panel mount style and solder pin termination method. Check for any updated environmental compliance documentation such as RoHS status directly from the manufacturer or authorized distributors prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when a dual row card edge interface is required for vertical panel mounting. It is suitable for applications demanding a 5 A current rating and operation within a -40°C to +105°C temperature range. Choose this model if the design specifies a 3.96 mm contact spacing and requires gold-plated contacts for corrosion resistance. Ensure the target PCB thickness aligns with the 1.57 mm nominal specification for proper mechanical fit.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations tailored for different board edge applications. The 305-046-556-512 specifically addresses needs for 46-position dual row connections. It utilizes a thermoplastic insulator and solder pin termination common across the family for consistent performance in industrial environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing identical 3.96 mm pitch and 46-position dual row layouts. Verify mechanical dimensions and electrical ratings match exactly before substitution. Ensure the replacement maintains the same vertical panel mount style and gold-plated contact finish.
