CS1W-CN226 Expansion Cable for CS1-Series PLCs | Omron Industrial-Grade Connectivity Solution

Premium Industrial Expansion Cable for Demanding Automation Environments

The CS1W-CN226 represents Omron's engineering excellence in industrial connectivity solutions, specifically designed to provide flawless signal transmission between CS1-series Programmable Logic Controllers (PLCs) and their expansion I/O units. This 2.6-meter shielded cable features military-grade 40-pin male connectors at both ends, engineered to maintain signal integrity in electrically noisy industrial environments. With its oil-resistant PVC jacket and gold-plated contacts, the CS1W-CN226 delivers reliable performance in temperature ranges from 0°C to 55°C, making it ideal for factory automation, process control, and heavy manufacturing applications.

Key Features and Technical Advantages

Installation Best Practices

For optimal performance of your CS1W-CN226 expansion cable:

• Maintain minimum 100mm separation from power cables carrying >10A current
• Use DIN rail-mounted cable clamps every 400mm to prevent mechanical stress
• Route cables in dedicated wireways or conduits to minimize EMI exposure
• Ensure connector seals are fully engaged in dusty or humid environments
• Avoid sharp bends - maintain >50mm radius throughout cable run

Quality Assurance and Compliance

Every CS1W-CN226 cable undergoes 100% electrical testing at Omron's certified manufacturing facilities, including:

• Continuity verification (all 40 pins)
• Hi-pot testing at 1000V AC for 1 minute
• Insulation resistance verification (500VDC)
• Mechanical mating force measurement
