PROXIMITY SWITCHES
Proximity Switches provide better alternative to the conventional electro-mechanical limit switches for position sensing. It is a best solution to all speed / counting / linear position sensing applications. They find wide application in Machine tools, Foundries, Rolling mills, Automobile, Textile, Pharmaceutical, Material handling and all automation systems in general. The proximity switches are generally available in tubular enclosures with diameter from 4 mm to 140 mm. These enclosures are made of Nickel Plated Brass, Stainless Steel or Engineering Plastics as required by the application. The proximity switches are available in both voltages AC & DC supply voltage. Proximity switches are available in Inductive, Capacitive, Optical and Magnetic sensing principle based on the object material and application.
