306-012-421-103

Edgeboard Connectors Overview

The EDAC Inc. 306-012-421-103 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features a single row of 12 positions with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are made of copper alloy and feature a tin plating finish to ensure reliable electrical connections. The insulator body is constructed from thermoplastic polyester, providing durability and stability in various industrial environments.

Edgeboard Connectors Feature Summary

• Accepts PCBs with a nominal thickness of 1.57 mm
• Features a low-profile insulator body design
• Utilizes a single centerline row configuration

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Electronic equipment utilizing standard 1.57 mm thick circuit boards
• Vertical mounting configurations in compact enclosures

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the contact plating and housing color, as variations exist within the 306 series. Confirm that the target application utilizes a 1.57 mm board thickness, as this connector is optimized for that dimension. Ensure the single-row, 12-position configuration aligns with the signal count requirements of the design. Cross-reference the manufacturer's current datasheet to validate compliance with relevant environmental standards such as RoHS before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for single-sided or dual-edge cards with a 1.57 mm thickness. The 3.96 mm pitch offers a balance between density and mechanical strength compared to finer pitches. Consider the tin-plated contacts for general-purpose applications where high corrosion resistance is not the primary constraint. Evaluate the need for a single row versus dual rows based on the total I/O requirements of the interface.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors for industrial and commercial electronics. The series provides various position counts and mounting styles, catering to diverse board integration needs. The 306-012-421-103 specifically addresses the need for a mid-count, single-row connector with a standardized 3.96 mm pitch, fitting into the broader portfolio of EDAC's interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 306 series parts with identical 12-position, 3.96 mm pitch, and 1.57 mm board thickness specifications. Verify that any alternative maintains the same vertical panel mount style and single-row configuration. Check for compatibility with existing tooling and panel cutouts if swapping between different manufacturers' offerings.
