306-025-421-112

Overview

The EDAC Inc. 306-025-421-112 is a standard card edge connector from the 306 series, designed for reliable signal transmission in electronic assemblies. It features 50 positions with a single centerline row and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes a dual female contact configuration. Constructed with copper alloy contacts finished in tin plating, it ensures durable electrical performance. The insulator body is made of thermoplastic polyester, providing structural integrity and low profile characteristics suitable for panel mount applications.

Feature Summary

• Features a low-profile insulator body design to minimize vertical space requirements within equipment enclosures.
• Utilizes copper alloy contacts with tin plating to ensure consistent electrical conductivity and corrosion resistance.
• Supports dual edge board insertion for secure mechanical engagement and stable signal transmission.

Applications

• Industrial control systems requiring robust panel-mounted interconnections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable PCB mounting solutions

Procurement Notes

Verify that the specific part number matches the required pin count and contact finish before procurement. Confirm compatibility with the target PCB thickness of 0.062 inches to ensure proper mechanical fit. Check for any updated RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure that the supplier provides genuine EDAC Inc. components to maintain quality standards.

Selection Notes

Select this component when a single-row, 50-position interface is required for dual-edge card applications. The 0.156-inch pitch offers a balance between density and manufacturability. Consider the tin-plated contacts if lead-free soldering processes are utilized or if specific environmental conditions favor tin over gold. Verify that the panel mount style aligns with the chassis design constraints.

Part Context

This connector belongs to the EDAC 306 series, which specializes in standard card edge connectors for various industrial and commercial applications. The series is known for offering multiple termination options and mounting styles. The 306-025-421-112 variant specifically addresses needs for higher position counts with a single row configuration, fitting into broader system architectures requiring standardized interconnects.

Replacement Considerations

Direct substitutes may include other EDAC 306 series parts with matching 50-position counts and 0.156-inch pitch. Verify that alternative models support dual-edge board insertion and have compatible termination types. Cross-reference pinouts and mechanical dimensions to ensure interchangeability without redesigning the host PCB or panel.
