Overview
The EDAC Inc. 306-026-521-158 is a dual-edge female card edge connector from the 306 Series, designed for panel and through-hole mounting. It features 52 positions arranged in two rows with a contact pitch of 0.156 inches (3.96 mm). The connector utilizes gold-plated cantilever contacts on a green thermoplastic polyester insulator. It supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual-edge female configuration with cantilever spring contacts for reliable signal transmission
- Panel mount design with flush mounting flange and top opening for secure installation
- Gold-plated copper alloy contacts ensure corrosion resistance and low contact impedance
- Thermoplastic polyester insulation provides stability across specified thermal ranges
Applications
- Industrial control systems requiring robust panel-mounted interconnects
- Telecommunications equipment utilizing standard card edge interfaces
- Test and measurement instrumentation boards
- General-purpose electronic assemblies needing high-density connections
Procurement Notes
Verify that the target printed circuit board adheres strictly to the specified thickness range of 0.054 to 0.070 inches to ensure proper mechanical engagement. Confirm that the mating card edge is non-specified dual-edge type compatible with the 0.156-inch pitch. Ensure the application environment remains within the -40°C to 105°C operating temperature limits defined by the manufacturer's specifications.
Selection Notes
Select this component when a dual-row female connector with a 0.156-inch pitch is required for panel installation. The 52-position count suits applications needing moderate density without excessive footprint. Consider the green thermoplastic polyester housing for general environmental protection. Verify compatibility with existing tooling for the 4-40 threaded plug mounting feature before finalizing the design.
Part Context
This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles tailored for industrial and commercial electronics. The 306-026-521-158 specifically addresses needs for dual-edge female connections with panel-mount capabilities, distinguishing it from surface-mount or single-row variants within the broader product line.
Replacement Considerations
Direct substitutes within the same series include parts with identical pitch and row configuration but different pin counts, such as 306-024-521-158 or 306-028-521-158. Cross-series replacements require matching the 0.156-inch pitch and dual-edge female interface. Always verify mechanical dimensions and mounting hole patterns before substituting.
