In modern industrial and technological applications, sensors act as the "sensory nerves" of equipment, constantly monitoring critical parameters such as temperature, pressure, displacement, and vibration. However, many sensors must operate in harsh environments such as high temperature, humidity, corrosion, and strong electromagnetic interference. How can we ensure their stable operation? Fiberglass sleeving—a seemingly ordinary material—has become an indispensable high-performance solution for sensor protection.

High-temperature protection ensures stable sensor operation

Sensors are often installed in high-temperature environments, such as around automotive engines, in industrial boilers, or inside electronic products, where temperatures can exceed 150°C or even higher. Ordinary plastic tubing easily softens and deforms, while metal sheaths are bulky and costly.

Fiberglass sleeving stands out for its excellent heat resistance, capable of operating in temperatures ranging from -40°C to 200°C without deformation or melting. Like a "heat-insulating suit," it wraps around sensor wiring harnesses or sensitive components, effectively shielding them from external heat sources, maintaining the sensor's internal temperature within a suitable range and ensuring accurate and consistent data collection.

High insulation performance resists electromagnetic interference

Many sensors are used in power systems, communications equipment, or variable frequency control applications, often surrounded by electromagnetic interference. Signal interference can cause misjudgments or even system downtime in the entire control system.

Fiberglass sleeving is made of woven glass fibers, which offer excellent electrical insulation properties. It is neither electrically conductive nor magnetic, effectively isolating external electric and magnetic fields. 

Lightweight and flexible, suitable for complex installation scenarios. 

Compared to metal sheaths or ceramic shields, fiberglass sleeving is lightweight, flexible, and well-suited for sensor wiring in confined spaces or complex structures, such as within robotic arms, robot joints, or precision instrumentation. 

It can be easily cut to size and applied directly to the wiring for ease of installation and low cost. It effectively resists external friction and minor impacts while reducing structural weight, meeting the demands of lightweight and highly integrated modern equipment.
