Overview
The EDAC Inc. 306-026-500-178 is a standard card edge connector receptacle featuring 52 positions in a dual female configuration. It utilizes a 0.156-inch (3.96 mm) pitch and supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The component employs through-hole termination with solder tail contacts, gold-plated copper alloy terminals, and a green thermoplastic polyester insulator. Rated for 5 A current, it operates within a temperature range of -40°C to 105°C.
Feature Summary
- Dual row female contact configuration for double-sided card edge interfaces
- Gold-plated copper alloy contacts ensure reliable signal transmission
- Thermoplastic polyester housing provides thermal stability and durability
Applications
- Industrial control system interconnections
- Telecommunications equipment backplanes
- Computing hardware motherboard connections
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal type and mounting style compatibility. Ensure the target PCB design accommodates the required 3.96 mm pitch and 1.57 mm maximum board thickness specifications before procurement.
Selection Notes
Select this component when a high-density 52-position interface is required for double-sided cards. Confirm that the application environment remains within the specified -40°C to 105°C operating range and that the mechanical fit aligns with the flush mount and straight installation style requirements.
Part Context
This part belongs to the EDAC 306 Series, designed for robust standard card edge applications. It serves as a vertical receptacle solution for connecting double-sided edgeboards to main systems, offering a balance of electrical performance and mechanical reliability for general-purpose industrial electronics.
Replacement Considerations
Cross-reference with other EDAC 306 series variants such as 306-026-500-104 or 306-026-520-103 for potential pin count or termination differences. Verify exact dimensional tolerances and contact plating specifications before substituting.
