Overview
The EDAC Inc. 306-035-520-158 is a dual-edge card edge connector featuring 70 positions arranged in two rows of 35 contacts each. It utilizes a 0.156-inch (3.96mm) pitch with female cantilever contacts designed for solder termination. The unit accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). Constructed with copper alloy contacts and gold plating, the insulator is made of thermoplastic polyester. It supports panel mounting via flange features including flush installation and top openings.
Feature Summary
- Dual-edge configuration providing 70 contact positions across two rows
- Cantilever contact type ensures reliable connection for specified board thicknesses
- Panel mount design incorporates flange features for secure mechanical attachment
Applications
- Industrial control systems requiring robust interconnect solutions
- Medical equipment utilizing EDAC medical interconnect components
- Agricultural technology applications demanding durable connectors
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure compatibility with required board thickness and mounting configurations. Confirm that the dual-edge specification aligns with the target PCB design requirements before procurement. Cross-reference the part number with current distributor listings to validate availability status and standard packaging quantities.
Selection Notes
Select this component when a high-density dual-edge interface is required for vertical panel mounting applications. The 0.156-inch pitch accommodates standard board layouts while the cantilever contacts provide flexibility during insertion. Ensure the target PCB thickness falls within the 0.054 to 0.070-inch range to guarantee proper contact engagement and electrical performance.
Part Context
This connector belongs to the EDAC 306 Series, which offers various position counts and mounting options. The series is characterized by its use of thermoplastic polyester insulators and gold-plated copper alloy contacts. It is designed for environments requiring reliable signal transmission through card edge interfaces.
Replacement Considerations
Consult the EDAC 306 Series Ordering Guide for direct substitutes with differing pin counts or mounting styles. Verify that alternative parts maintain the same 0.156-inch pitch and dual-edge configuration to ensure mechanical fit.
