             Bee Instruments has been manufacturing quality Proximity Switches since 1976. As one of the largest manufacturer’s, we offer over 500 models of Inductive, Capacitive, Optical, Ultrasonic & Magnetic Proximity Sensors. With continuous induction of latest technologies, our proximity switches are keeping pace with time. With over 1500 satisfied customers spread all over India & abroad, we are committed to maintain high standards in Quality and Prompt Services.

Application:- Proximity switches provide better alternative to the conventional electro-mechanical limit switches for position sensing. It is a best solution to all linear / rotary counting applications. They find wide applications in Machine tools, Foundries, Rolling mills, Automobile, Textile, Pharmaceutical, Material handling and all automation systems in general.

Construction:- The Proximity Switches are generally available in tubular enclosures with diameter from 4 mm to 140 mm. These enclosures are made of Stainless Steel, Nickel Plated Brass Tube or Engineering Plastics as required by the application.

These switches are totally epoxy potted to meet IP-67 grade of protection. The switches are also available in various other shapes such as Rectangular, Slot, Block, Button and Insert type modules. Our Proximity Switches meet CE requirements.
