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.

Applications

• 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.

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 Level• Food /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.
