Overview
The EDAC Inc. 306-023-521-102 is a standard card edge connector from the 306 series, designed for panel mount installation with a vertical orientation. It features 46 positions arranged in a dual-edge configuration, utilizing a 3.96 mm (0.156 inch) contact spacing. The connector accepts printed circuit boards with a thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). Constructed with copper alloy contacts and a green thermoplastic insulator body, it employs a solder pin termination method. The unit is RoHS compliant and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual-edge female connector design accommodating non-specified card types
- Low profile insulator body with single centreline row architecture
- Panel mount installation style with vertical alignment
- Gold-plated copper alloy contacts for reliable signal transmission
Applications
- Industrial control systems requiring robust panel-mounted interconnects
- Telecommunications equipment utilizing standard card edge interfaces
- Test and measurement devices needing high-density vertical connections
- Automotive electronics assemblies compatible with specified board thicknesses
Procurement Notes
Verify that the specific part number matches the required 46-position dual-edge configuration before ordering. Confirm that the receiving PCB thickness falls within the 1.37 mm to 1.78 mm specification to ensure proper mechanical engagement. Check for any regional distribution restrictions or lead time variations associated with the EDAC 306 series. Ensure compatibility with existing panel mounting hardware and vertical space constraints in the final assembly design.
Selection Notes
Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch offers a balance between density and ease of manufacturing. Consider the gold plating for environments where corrosion resistance is critical. Verify that the operating temperature range of -40°C to +105°C meets the environmental demands of the target application. Compare against single-row alternatives if space allows for reduced position counts.
Part Context
This connector belongs to the EDAC 306 series, which provides various design options for card edge applications. The series supports multiple position counts and termination styles, allowing designers to tailor interconnect requirements. The 306-023-521-102 specifically addresses needs for higher position counts in a dual-edge format, differing from single-row variants like the 306-021 series.
Replacement Considerations
Direct substitutes within the same series include 306-023-521-102 variants with different plating or flange options. Cross-series replacements require matching the 3.96 mm pitch and 46-position count. Verify that alternative parts support the same dual-edge card type and panel mount orientation to maintain mechanical integrity.
