Introduction

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.

Advantages:-

1) Non-Contact sensing	8)Works in rugged Industrial Environment consisting of dust, water, lubricants and cutting oils
2) No operating force necessary	9) High switching frequency
3) No mechanical moving parts	10) High repeat accuracy
4) No backlash	11) Visual LED indication for presence of object
5) Bounce-free operation.	12)Suitable for Intrinsically Safe operation in Hazardous areas
6) Operation possible from different directions	13) Withstands vibrations and mechanical shocks
7) Compact sizes and versatile sensing arrangement	14) Long and maintenance free life

Types of Proximity Switches:- A critical element of sensing, automation & control, Proximity Switches are available in Inductive, Capacitive, Optical, Ultrasonic & Magnetictypes based on the object sensing principle
