Overview
The EDAC Inc. part number 306-022-521-158 is a dual-edge female card edge connector from the 306 series. It features 44 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated cantilever contacts and is designed for panel mounting. It accepts printed circuit boards with a thickness ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The insulator material is thermoplastic polyester, and the unit operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual-edge female configuration with cantilever spring contacts for reliable board insertion
- Panel mount design with flange features for secure mechanical installation
- Gold-plated contacts ensure corrosion resistance and stable electrical performance
Applications
- Industrial control systems requiring robust card edge interconnects
- Medical equipment utilizing standardized connector interfaces
- Telecommunications infrastructure hardware modules
Procurement Notes
Verify the specific suffix codes against the manufacturer's ordering guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm RoHS compliance status if required by project regulations. Cross-reference the basic product number 306-009 for series-specific dimensional constraints.
Selection Notes
Select this component when a dual-edge female interface with 0.156-inch spacing is required for panel-mounted applications. The 306 series offers a low-profile body suitable for space-constrained enclosures. Consider the cantilever contact type for ease of board insertion and removal during maintenance or module replacement cycles.
Part Context
This connector belongs to the EDAC 306 series, which provides standard card edge solutions for various industries. The series is characterized by its thermoplastic polyester insulation and gold-plated copper alloy contacts. It serves as a reliable interconnection solution between backplanes and daughter cards in electronic assemblies.
Replacement Considerations
Consult the EDAC 306 series ordering guide for direct substitutes with different pin counts or flange variations. Verify that any alternative part maintains the same 0.156-inch pitch and compatible PCB thickness range to ensure mechanical fit.
