Overview
The EDAC Inc. 306-034-521-158 is a dual-edge female card edge connector from the 306 series, featuring 68 positions with a 0.156-inch (3.96mm) pitch. It utilizes gold-plated cantilever contacts and a green thermoplastic polyester insulator. Designed for panel mounting via flanges with top openings, it accommodates PCB thicknesses between 0.054 and 0.070 inches. The component operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual-edge female contact configuration for secure board insertion
- Gold-plated cantilever spring contacts ensure reliable electrical connection
- Panel-mount design with integrated flanges for mechanical stability
Applications
- Industrial control system backplanes
- Telecommunications equipment interconnects
- Automotive electronic module connections
Procurement Notes
Verify that the specific part number matches the required 68-position count and 0.156-inch pitch before procurement. Confirm that the gold plating specification aligns with environmental requirements. Ensure the panel mounting flange dimensions are compatible with the assembly chassis. Cross-reference the operating temperature range against the application environment to guarantee reliability under thermal stress conditions.
Selection Notes
Select this component when a dual-edge interface with high pin density is required. The 0.156-inch pitch allows for broader spacing compared to finer pitches, aiding in manufacturing tolerance. The gold finish provides superior corrosion resistance for harsh environments. Verify that the target printed circuit board thickness falls within the specified acceptance range to ensure proper contact engagement.
Part Context
This connector belongs to the EDAC 306 series, which specializes in standard card edge solutions. The series offers various position counts and termination options. This specific model represents a mid-range density option within the lineup, balancing connectivity needs with physical footprint constraints for general-purpose industrial applications.
Replacement Considerations
Compatible substitutes include other EDAC 306 series connectors with matching 68 positions and 0.156-inch pitch. Verify that alternative parts maintain the same dual-edge female configuration and panel-mount flange specifications to ensure interchangeability without mechanical modification.
