Our Products
We are leaders in the market for providing best range of Optical Proximity Switches, Magnetic Proximity Switch, Inductive Proximity Switches, Capacitive Proximity Switches and Magnetic Proximity Switches
Introduction
Sai Control System offers optical proximity switches with modulated Infra Red beam consisting of transmitter and receiver. The state of the art modulation and detection circuit ensures reliable operation of sensor in hostile environment and are unaffected by temperature variation and stray light.
Applications
These are widely used for sensing metals and non metals like wood, glass, paper and water etc. These switches are used for automation in various industries like pharmaceuticals machines, packaging machines, food processing, textile machines, conveyor system, automobile engineering industries, cement plants, safety and security appliances.
| Operating PrincipleThe LC Oscillator circuit generates the electromagnetic field over the active face, energy is drawn from oscillator resulting damping of the oscillator. This change is detected by electronic circuit and is converted into an effective output signal. | ||
| ApplicationFor position sensing in Automation. AutomobileFoodPharmaceuticals.SteelCementEngineering Industries | ||
| Sensing DistanceThe sensing distance is the distance between the target and sensing face at which the switch operates. The sensing distance is usually specified considering M.S. as sensing objects. | ||
| Correction Factor For Inductive Proximity Switch |
Introduction
The capacitive proximity switches are used for sensing metallic as well as non metallic material.
The Major Applications of Capacitive Switches
Liquid level / Plastic Granules/ Component /Sand / Bulk Material LevelFood /Grain / Paper & Rubber/ Glass Industries
Working Principle
The switches works on the principle of resonant oscillator circuit. Two brass plates are used as electrodes of capacitor & the sensing objects acts as a dielectric media. The change in capacitance the object is sensed by a sensing circuit and output signal is generated
The Magnetic Proximity Switches are available in Two Categories.
Position sensing switches with Reed Element.2 Wire/ 3 Wire Hall Effect Sensor.
The Magnetic Proximity Switches are available in different shapes and sizes.
These switches incorporated hermetically sealed reed element, the sensing object should be a magnetic only. These switches are provided with 2/3 Core built in cable and output is potential free contact & PNP as well as NPN output is available to switch external load directly.
The switching voltage and contact rating depends upon switch size. Special model of latching type switched are available. High temperature magnetic switches are also available.
