TopWorx GO Switch Position Sensing Overview

Leverless Limit Switches built to last in the most demanding plant conditions GO^®Switch leverless limit switches provide reliable, durable position sensing in the most demanding plant conditions. Unlike mechanical limit switches or inductive proximity sensors, GO Switches use a unique hybrid technology that eliminates wear and tear. As a result, GO Switches are more dependable and last longer in the toughest applications.	The GO Switch Difference Unique hybrid technology. GO Switches have a one-of-a-kind “leverless limit switch” design that combines the advantages of existing limit switch and proximity sensor technologies. As a result, GO Switches deliver better performance in the most demanding applications. Reliability in a variety of industries. For over fifty years, GO Switches have set the standard for mission-critical position sensing in the automotive, cement, chemical, die casting, food & beverage, hydrocarbon, manufacturing, mining, oil & gas, petrochemical, power generation, pulp and paper, steel & aluminum, tire & rubber, and water & wastewater industries. Durability when it matters most. GO Switches last longer in plant conditions that are hot, cold, wet, dirty, abusive, corrosive, and explosive. A wide variety of GO Switches are certified for use in all hazardous areas including Zone 0 (intrinsically safe), Zone 1 (explosion proof), and Zone 2 (non-incendive). With no exposed moving parts and no delicate electronics, GO Switches have been designed to withstand caustics, corrosives, salt water, submersion, physical abuse, vibration, and temperatures ranging from -58°F/-50°C to 400°F/204°C.
