Speed Switches

Speed Switches

Speed Switches are non-contact devices used to monitor over-speed and under-speed in rotary or linear motion, helping improve safety and prevent equipment damage. These units work with a sensor probe and monitoring unit, and are suitable for both indoor and outdoor applications with different enclosure options. Standard models allow easy setting through a potentiometer, while advanced versions offer features like digital display, 4–20 mA output, and RS-485 connectivity.

With a wide range of inductive, magnetic, and optical sensors, these switches can measure speeds from 0.1 to 10,000 RPM. They are widely used in applications such as belt conveyors, wind speed monitoring, and bulk material handling industries like coal, cement, fertilizer, and sugar.

With over 40 years of experience and thousands of installations worldwide, Jayashree Electron delivers reliable and high-performance speed monitoring solutions designed for accuracy, durability, and efficient operation.
