Operating Temperature of Industrial-Grade Switches
Industrial switches are usually designed with a wide range of temperature adaptability, and their operating temperature range is generally -40 ° C to 85 ° C. The operating temperature of a network switch is one of its most fundamental specifications, directly affecting performance, reliability, and service life. When selecting a network switch, many users notice that operating temperature ranges can vary significantly and are often unsure how to choose. By leveraging industrial-grade Ethernet switches that are designed and built to withstand extreme conditions, organizations can build redundant networks that will operate regardless of location. They are built to exceed the specifications of commercial switches with industrial safety. With the rapid development of IIoT, networking applications have penetrated into various industrial scenarios.
