Overview
The EDAC Inc. 306-026-421-112 is a standard card edge connector from the 306 series, designed for panel mount applications with a vertical orientation. It features 26 positions in a single row and utilizes a 3.96 mm (0.156 inch) contact spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The housing is constructed from thermoplastic polyester, while contacts are made of copper alloy with a tin plating finish.
Feature Summary
- Accepts PCBs with a nominal thickness of 0.062 inches
- Features a low-profile insulator body design
- Utilizes a single centerline row configuration
Applications
- Panel-mounted electronic assemblies requiring vertical interconnection
- Single-sided or double-sided PCB integration systems
- Industrial control hardware utilizing standard density card edges
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number with official EDAC documentation. Confirm that the specific ordering suffix matches the required contact plating and board thickness specifications. Ensure compliance with relevant environmental standards such as RoHS before finalizing procurement orders to avoid compatibility issues.
Selection Notes
Select this connector when a vertical, panel-mount solution is required for single-row card edge interfaces. The 3.96 mm pitch accommodates standard board thicknesses, making it suitable for general-purpose industrial applications. Consider the tin-plated contacts for cost-effective solutions where high corrosion resistance is not the primary constraint compared to gold-plated alternatives.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its versatility in accepting various board thicknesses and offering both single and dual-edge configurations. The 306 series provides reliable interconnection solutions for dense PCB layouts in demanding environments.
Replacement Considerations
Compatible substitutes within the same series include part numbers such as 306-026-421-158 and 306-026-421-168. Verify that any replacement maintains the identical 26-position count, 3.96 mm pitch, and single-row architecture to ensure mechanical and electrical compatibility.
