Proximity Sensors

Jayashree Electron has been manufacturing
quality Proximity Switches for since year 1980. As
one of the largest manufacturers, 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 Service.
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
application 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
