Inductive Proximity Sensors
Proximity Sensors are used for non-contact metal sensing. Being contact-less
sensors these can be used for position sensing, speed measurement, counting,
etc. They can be used in extreme conditions, such as oily, dusty, corrosive
environment. Their application ranges from automobile industries to steel
industries, from CNC / NC machines to material handling equipments, process
automation, conveyor systems, packaging machines.
Proximity Sensor is designed to detect, and react to any object which moves
into the operating zone. The sensor contains an oscillator. The capacitance of
this oscillator is linked with the sensing face and when any object moves into
the operating zone, its capacitance activates the oscillator. The sensor can
detect conductive as well as non conductive material. It is advisable to have
an object with permittivity more than one. The conductive objects are
generally to be earthed for better results.
Sensor works on the principle of modulated Infra-Red rays. These sensors can
sense any opaque, semi-transparent objects which comes in its sensing range.
Photoelectric Sensors have large operating distance. These are mainly divided
into : Diffused Beam Sensor, Through Beam Sensor with Amplifier Unit, Through
Beam Sensor with Built in Amplifier, Retro-Reflective Sensors.
Print Mark Sensors
- This is
designed for sensing registration mark. It continuously scans the presence of
registration mark on the moving packaging film. The electronic circuitry is
capable of detecting any colours on any background colour. The scanning rate
is as high as 2000 packages / minute making it suitable for any type of
packaging machine including candy packing machine.
Electronic Safety Guards
safety guard is mainly designed for human safety. It is a invisible barrier of
Infra Red Beam installed in dangerous operating areas to provide maximum
safety to operators working on automatic machines, hydraulic presses, shearing
machines, printing presses etc. It also provides flexibility in working areas,
which in turn increases productivity and ensures machine safety also.
