Overview
The EDAC Inc. part number 306-025-420-158 is a standard card edge connector from the 306 Series. It features 50 positions with a 3.96 mm (0.156 inch) pitch. The connector is designed for dual-edge, non-specified cards and utilizes female contacts with tin plating. It supports panel mounting in a vertical orientation and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, and the contacts are made of copper alloy.
Feature Summary
- Dual-edge female contact design for secure connection to non-specified circuit boards
- Panel mount vertical installation style for robust structural support
- Tin-plated copper alloy contacts for reliable signal transmission
Applications
- Industrial control systems requiring durable interconnects
- Test and measurement equipment interfaces
- Telecommunications hardware connections
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required contact finishes and mounting styles. Confirm that the tin plating specification aligns with your application's environmental requirements. Cross-reference the 306 series documentation for accurate dimensional drawings and mating card specifications before finalizing procurement decisions.
Selection Notes
Select this component when a high-density 50-position interface is required for dual-edge cards. The 3.96 mm pitch accommodates standard board widths. Ensure the vertical panel mount configuration fits the enclosure constraints. Verify that the operating temperature range and insulation material properties meet the system's thermal and chemical exposure standards.
Part Context
This component belongs to the EDAC 306 Series, which provides a comprehensive range of card edge connectors. The series offers various position counts and mounting options. The 306-025-420-158 specifically addresses applications needing a substantial number of connections in a compact vertical profile. It is part of a modular system allowing for mixed configurations.
Replacement Considerations
Compatible substitutes within the same series include 306-025-420-101 and 306-025-420-158 variants with different plating or packaging. Verify mechanical dimensions and electrical ratings match exactly before substitution.
