Proximity sensor
A proximity sensor is
a sensor able to detect the presence of nearby objects without any physical
contact. A proximity sensor often emits an electromagnetic field or a beam of
electromagnetic radiation, and looks for changes in the field or return signal.
 
Applications
Due to their
reliability and efficiency, inductive proximity switches are used whenever a
metal object has to be detected within just a few millimeters:
·      
Presence detection of
a machine component
·      
Ultra precise
referencing of the zero position of a moving machine component (e.g. in
robotics)
·      
Detection of different
positions (e.g. limit switches)
·      
Counting metal objects
(e.g. in component feed or conveyor technology)
·      
Presence detection
of objects in process
·      
Rotary speed
measurement on metal gear wheel
 
Features:
·      
This is a normally open
proximity switch sensor with 10mm detection distance.
·      
When proximity switch is close
to some target object, it will send out control signal.
·      
It is a component widely used
in automatic control industry for detecting, controlling, and non-contact
switching.
·      
High sensitivity, quick
response, stable performance.
·      
Non-contact detection avoids
the sensor and the target object from damages.
