Capacitive Proximity Switch

Item Code: SW-505
The series SW 505 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.

Specifications:
• Liquid level
• Plastic granules & parts
• Sand / Bulk Material Level
• Food / Grain / Confectionery
• Paper & rubber
• Glass bottles / Tins in packaging

Working Principle:
The switch works on the principle of resonant oscillator circuit. A pair of brass/copper disc from the electrodes of a capacitor & the object acts as a dielectric media. The change in capacitance value, due to presence of object, is sensed by a precision integrated circuit. An effective output signal is generated at a preset value of capacitance.

Construction:
These are offered in tabular threaded housing from size M12 to M80. The enclosures are made of Brass, Stainless steel or Engineering plastics. Special shapes, teflon housings are provided against requirements. Standard models are provided with an integrated 2 meter long cable. Connector type versions are available with built-in male connectors.

The nominal sensing distance of any size of switch is specified with Water as standard object and tested at 25°C. Depending upon the material of the object to be detected, the distance will vary. The sensitivity of the sensor is adjustable with a trimpot provided usually on the rear side of the sensor. Typical Sensing distance chart for a M30 size sensor, for different objects is shown in Fig.1

Effect of Ambient Conditions on Sensitivity:
The sensing distance is affected by change in ambient temperature, humidity, size and material of the object.

Specifications:

Protection:
All the Capacitive switches are provided with Reverse polarity, Overload, short circuit and false pulse protections. Rugged construction along with IP-67 grade of protection renders these switches to be very useful for liquid level monitoring applications.

Magnetic Proximity Switch

Series - SW 705 / SW 715 / MSP 706/MSP 716 MSP 707/MSP 717
The series SW 705 Magnetic Proximity Switches are available in two broad categories.
• Position sensing switches with Reed Element.
• 2-Wire / 3-Wire Magnetic pick-up Sensors.

These switches are available in different shapes and sizes. Tubular models are available in Brass/SS enclosures in sizes M12, M18 and M30 and above.

Switches With Reed element:
These switches are used only for position sensing application. These incorporate a hermetically sealed sensitive reed element. The object should necessarily be a magnet. These are provided with 2-core built-in cable. The output is a potential free contact and can switch external load directly. The switching voltage and contact rating depends upon switch size. Special models of latching type switches are available for direction sensing applications.

Applications:
Position sensing in hydraulic cylinders, Roto-meters, Direction sensing applications Level sensing of liquids

Magnetic Pick-Up Sensors:
Series MSP 706/MSP 716

Hall Effect Sensors:
• Series MSP 707/MSP 717

These sensors can be used only for sensing motion of a ferrous object e.g. Gear Wheel. These incorporate a special high strength ALNICO Magnet with a properly designed coil. Special high frequency sensors incorporate a Hall effect sensor.
These switches are available in 2/3-wire design. The 3-wire type switches have output logics / operating voltages similar to other types of switches described earlier. The 2-wire switches should be necessarily used with a special controller / amplifier unit.

Applications:
• Turbine high-speed sensor.
• Bucket Elevator high temperature sensor.

Automobile Sensors:
Special / custom built models are available for Automobile applications as below
• Transfer case speed sensor.
• Wheel Rotation sensor for Fare-meter.

Inductive Proximity Switch

Item Code: SW-405
Principle of Operation:
Series SW 405 Inductive Proximity Switches available in varied shapes & sizes, are a reliable option for applications in Machine tools, Foundries, Rolling mills, Automobiles, Textiles, Pharmaceuticals and Material Handling systems. This type of switches work on 'Damped Oscillator' principle. During operation a frontally radiated electromagnetic oscillating field is projected from the sensing face. Any electrically conductive material entering this field causes damping of the oscillation.

Applications:
• Bulk Material handling
• Automobile
• Steel Plants
• Fertilizer
• Cement
• Engineering Industries

Sensing Object Material:
The 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 (Cu, Al etc.) objects.

Sensing 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 at which the switch operates. This is usually specified considering M.S. as target material.

Correction Factor:
Targets 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 "Nonferrous sensing models."

Nonferrous Inductive Switches:
All standard inductive switches sense presence of any metal but will offer stated sensing distance only for ferrous materials like MS. The type SW 4051-NF is specially developed to sense only non-ferrous metals such as Copper, Aluminium, Gold, Tin, Zinc etc. The biggest advantage of this type of switch is that the non-ferrous objects are sensed from larger distances as compared to standard models. These switches are available in M18 and above sizes. The other operating features are same as those of standard 3 wire DC switches.

High Pressure Switches:
Special high pressure type Inductive Proximity Switch has been developed for direct use in a Hydraulic cylinder.
The switch construction is sturdy and is rated for pressure upto 500 bar. These switches are also available in connector version for easy replacement.
• Switches in standard Tabular Enclosure
• Switches in Square/Slot/Rectangular shape
• Switches with Built in Connector
