INTRODUCTION

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
