Overview
The EDAC Inc. 306-025-520-103 is a standard card edge connector designed for vertical panel mounting applications. It features a single row of 50 female positions with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts and gold plating, it ensures reliable electrical performance. The insulator body is made of thermoplastic material, providing durability in demanding environments.
Feature Summary
- Vertical panel mount design for secure installation
- Single centerline row configuration for compact layout
- Gold-plated copper alloy contacts for conductivity
- Compatible with 1.57 mm nominal PCB thickness
Applications
- Industrial control systems requiring robust interconnects
- Panel-mounted electronic equipment interfaces
- High-density signal routing in specialized hardware
- Automated testing and measurement device connections
Procurement Notes
Verify the specific ordering suffix to confirm contact count, plating type, and board thickness compatibility before purchase. Ensure the selected variant matches the required PCB dimensions and mounting style. Cross-reference the manufacturer datasheet for precise dimensional tolerances and environmental ratings to guarantee system integration success.
Selection Notes
Choose this connector when a single-row, high-position count interface is required for thick PCBs. The 3.96 mm pitch suits applications where space efficiency is less critical than mechanical stability. Verify that the target PCB utilizes the specified 1.57 mm thickness to ensure proper mating force and retention.
Part Context
This component belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles to accommodate diverse electronic assembly needs. The 306 series is recognized for its reliability in industrial and commercial sectors requiring durable board-to-panel connections.
Replacement Considerations
Direct substitutes within the same series include part numbers such as 306-025-520-107 or 306-025-520-112, provided they match the 50-position count and 3.96 mm pitch specifications. Always verify dimensional drawings and electrical ratings before swapping components.
