Overview
The EDAC Inc. 306-031-421-104 is a dual-sided card edge connector designed for panel and through-hole mounting. It features 62 positions with a 0.156-inch (3.96mm) contact spacing across two rows of 31 contacts each. The connector utilizes copper alloy cantilever contacts with tin plating, housed in a green thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm).
Feature Summary
- Dual-sided female contact configuration for secure board insertion.
- Cantilever spring contact design ensures reliable electrical connection.
- Thermoplastic polyester insulator provides high-temperature resistance.
- Panel mount flange with top opening facilitates installation.
Applications
- Industrial control systems requiring robust interconnects.
- Telecommunications equipment backplanes.
- Test and measurement instrumentation modules.
- Automotive electronic control units.
Procurement Notes
Verify the specific part number suffix against official EDAC documentation to confirm exact pin count and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference manufacturer datasheets for precise mechanical dimensions and mating force requirements.
Selection Notes
Select this component when a dual-sided, through-hole card edge connector with 0.156-inch spacing is required. Evaluate the 62-position capacity against signal routing needs. Consider the operating temperature range of -40°C to 105°C for environmental suitability. Verify that the cantilever contact type matches the insertion and extraction force constraints of the application.
Part Context
This connector belongs to the EDAC 306 series, which offers various mounting options and contact configurations. The series is characterized by low-profile insulator bodies and standardized spacing. It serves as a standard interconnect solution within the broader category of card edge connectors, providing reliability for repeated mating cycles in industrial environments.
Replacement Considerations
Direct substitutes may include other EDAC 306 series variants with matching 62-position counts and 0.156-inch spacing. Verify mechanical footprint and terminal pitch compatibility before substitution. Consult official cross-reference guides for equivalent parts from other manufacturers meeting identical electrical and mechanical specifications.
FAQ
