Why Micro Coaxial Cables Are Preferred in Industrial Automation Sensors

Quality and reliability of information transfer can make or break a production line in industrial automation. As factories grow smarter and more connected, the demand for robust, sophisticated sensor systems is skyrocketing. At the heart of these systems sit micro coaxial cables—often overlooked, frequently underestimated. Yet Hotten Electronic Wire’s development of ultra-fine coaxial solutions for the most demanding applications has quietly shown why this cable technology has become the undisputed standard for industrial sensors today.

Fundamental Considerations: Signal Integrity in Unfriendly Situations

Industrial environments don’t play nice—physically or electrically. Machinery churns out heavy electromagnetic interference (EMI), temperatures swing unpredictably, and cables are constantly flexed, vibrated, and exposed to oils or chemicals. Conventional wiring often struggles here, leading to corrupted data, lost signals, and costly downtime. Pressure, position, temperature, or vision sensors must transmit their readings without compromise. That’s exactly where micro coaxial cables step in—and prove their worth.

Key advantages driving their adoption in automation:

Unshaken Signal Performance Under EMI Attack

Electromagnetic compatibility isn’t just a feature—it’s the lifeline. A micro coaxial cable is built like a precision transmission line: a central conductor wrapped in dielectric insulation and shielded by multiple layers (typically foil plus braid). This structure acts as a Faraday cage, shielding sensitive sensor signals from external EMI generated by motors, drives, and wireless systems—while also preventing the signal itself from leaking out and interfering with other equipment. The result? A millivolt signal from a strain gauge or a high-frequency stream from a vision camera reaches the controller clean, intact, and uncorrupted.

High-Speed, Data-Intensive Sensing Needs High Bandwidth

Modern automation runs on high-resolution industrial cameras (often using LVDS or similar interfaces), LiDAR, and precision radar—all generating massive amounts of data that must move in real time. Micro coaxial cables excel at high frequencies with low attenuation (minimal signal loss), making them ideal for carrying both high-speed digital and analog signals across machines or cells without weakening. This capability is essential for real-time process control and instant quality verification.

Mechanical Toughness Built to Last

Industrial cables aren’t just installed and forgotten—they’re put through a lifetime of abuse. Hotten’s micro coaxial cables are engineered for high flex life, crush resistance, and vibration tolerance. They use fine-stranded conductors and special jacketing materials (oil- and chemical-resistant, as seen in our Robotics Wire Harnesses) to endure the constant motion of robotic arms, the repetitive thrust of linear actuators, and the general wear and tear of the factory floor. This durability keeps electrical performance stable over millions of cycles—eliminating those frustrating intermittent faults.

Miniaturization Meets Real-World Design Needs

As sensors and connectors shrink, designers must squeeze everything into tighter spaces inside smaller machines and robots. Cabling has to shrink too—without sacrificing performance. Micro coaxial technology delivers just that: an extremely small outer diameter paired with excellent signal integrity. In today’s crowded control panels packed with miniaturized sensors, this compact size isn’t optional—it’s essential to keeping signals strong and clear.
