IntroductionThe Optical Proximity Switches are a reliable solution for automation where other Proximity Switches have limitations.These are Infra-red type sensors incorporating advance and reliable technology.These switches have a distinct advantage of higher sensing distance over Inductive and capacitive type switches.
These can work more reliably in a noisy electro-magnatic radiation environment. As an infra-red wavelength is used, it is immune to visible light interference.Applications
These switches are very useful for counting and position sensing application in Pharma, food, Paper, Plastic Automobile industry. They also work effectively in level sensing applications for solids, grains, sand, ice and other non-metallic bulk material. Some typical applications are;
Component positioning sensing in Electronic Industry
Counting of bottles, Jars, Containers etc.
Glass sheet position sensing
For security 7 safety in machine Tools, presses etc.
Colour sensing applications
Principal Of OperationThese Switches incorporates an infra-red transmitter and receiver device hose in single enclosure or separate enclosure. The precision pulsed transmitter beam is interrupted or reflected by the object. The advanced electronic circuit generates an effective output signal when the object is sensed.Diffused Scan:
Diffused scan type switches have both transmitter and receiver is same enclosure.
The closely focused beam is reflected back by the object.
Through-Beam: Through-Beam type switches have separate transmitter and receiver. The object is sensed when the beam is interrupted.Retro Reflective: Retro reflective switches use a special reflectorto reflect back the beam. When an object interrupt the beam, an output signal is generated. These model have greater sensing distance compare to diffuse scan type. The receiver does not considerthe reflection from the object.Technical Terms
Standard ObjectThe sensing distance specified for diffused scan switch is considered with a white object having minimum 90% reflectivity.ConstrictionThese switches are offered in tubular metallic, Acrylic and Plastic enclosure. Standard model are available with integrated two meter long cable. Switches with built in (Male) connector.

Principle Of OperationInductive proximity Switches available in Varied shapes size, are a reliable option for applications in Machine tools, Foundries, rolling mils, Automobile, textiles, Pharmaceuticals and Material Handling systems.This type of switches work on ‘Damping’ principle. During operation a frontally radiated electromagnetic oscillating field is projected from the sensing face. Any electrically conductive material entering this field causes damping ofthe oscillations.
This change is detected by the in-built sensitive & reliable electronic circuit and is converted into an effective output signal.
Applications
For Counting / Position Sensing of various objects in
Bulk Material handing
Automobile
Steel Plants
Fertilizer
Cement
Engineering Industries
Sensing Object MaterialThe standard inductive proximity Switches can sense any metallic (electrically conductive) object. However, we have special type of switches to sense either only ferrous objects or sense only non-ferrous sensing switches are describedSensing Zone
This switch has a dome shaped electro-magnetic field present in front of the sensing area.
The switch will sense the object entering into this domain.
Sensing Distance (Sn)This is the distance between the target and the sensing face with the switch operates. This is usually specified considering MS. as target material.Correction FactorTargets other than MS actuate the inductive Switches at relatively less distance with correction factor as given below. However this criteria is not applicable to special “Non-ferrous sensing models”.

Capacitive Proximity SwitchesIntroductionThe capacitive Proximity Switches are designed for sensing wide range of materials. These switches give a superior performance for detection of various non-metallic objects where inductive type switches can not function.Applications:
Liquid Level
Plastic granules & parts
Sand / bulk material Ievel
Food / Grain / Confectionery
Paper and Rubber
Glass Bottles / Tins in packaging
Working PrincipleThe switch works on the principle of resonant oscillator Ckt. A pair of Brass/ Copper disc form the electrodes of a capacitor and the object acts as a dielectric media. The change in capacitance value, due to presence of objects, is sensed by a precision integrated circuit.Connection Diagrams3-Wire & 4Wire DCThese switches operate on 10-30 V Dc and can be used with Logic Circuits, Counters or to drive Relay Coil directly. The output of there switches can be either PNP or NPN or both. The switching is in the sourcing mode and the load must be connected between the Output and the Negative of the supply. Conversely, with NPN output switching is in sinking mode & the load must be connected between the output & the positive of the supply. All 3 wire & 4 wire DC switches are internally Protected against Inductive voltage peaks. Spurious Iine pulses, Reverse polarity short circuit conditions.
2-Wire DCThese switches are designed to operate external Loads connected in series with the switch. During operation, there is a voltage drop of about 6 V across the switch & the load connected in series gets the supply voltage reduced accordingly.2-Wire ACThe AC switches are designed for 2 wire connected and operate on full line voltage. The loads are to be connected in series with the switch in a similar manner to that of a mechanical limit switch. The external PLC, Contactor, Relay etc. The operating (OFF state) current ofthese switches is less than 3 mA.Generally the continuous load current should be restricted up to 60% of specified load current.
