Overview
The EDAC Inc. 306-034-521-168 is a dual-edge female card edge connector featuring 68 positions with a 0.156-inch (3.96mm) contact spacing. Designed for through-hole panel mounting, it utilizes gold-plated cantilever contacts and a green thermoplastic polyester insulator. The unit accommodates printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). It operates within a temperature range of -40°C to 105°C and includes flanges with 4-40 threaded inserts for secure installation.
Feature Summary
- Dual-edge female configuration with cantilever contact type
- Gold-plated terminals for reliable signal transmission
- Panel mount design with integrated guide rails
- High-temperature resistant thermoplastic polyester insulation
Applications
- Industrial control system interconnections
- Telecommunications equipment backplanes
- Consumer electronics module interfaces
- Medical device internal board connections
Procurement Notes
Verify the specific part number against official EDAC documentation to confirm pin count and spacing alignment. Ensure that the target PCB thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Confirm RoHS compliance requirements match project specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual-sided connection is required for high-density applications. The 0.156-inch pitch suits standard board layouts requiring robust mechanical retention. Consider the through-hole termination method for superior durability compared to surface mount alternatives in vibration-prone environments.
Part Context
This connector belongs to the EDAC 306 series, which specializes in card edge solutions. The series offers various position counts and mounting options. This specific model provides a balanced combination of density and mechanical stability, suitable for general-purpose industrial and commercial electronic assemblies requiring reliable dual-edge connectivity.
Replacement Considerations
Cross-reference compatible parts within the EDAC 306 series for alternative pin counts. Verify that substitute models maintain identical 0.156-inch spacing and dual-edge female configurations. Ensure any replacement matches the thermal rating and mounting flange specifications for direct interchangeability.
