12 Questions
What is the main principle behind the operation of an inductive proximity sensor?
It generates an alternating magnetic field that is modified by the presence of a metallic object.
What is the typical operating range of a capacitive proximity sensor?
1 - 10 mm
Which type of photoelectric sensor uses a light source and a reflective surface to detect the presence of an object?
Retro-Reflective
What is the main difference between inductive and capacitive proximity sensors?
Inductive sensors can only detect metallic objects, while capacitive sensors can detect any type of object.
What is the primary purpose of a proximity sensor?
To detect the presence of an object without physical contact.
Which type of photoelectric sensor uses a light source and a semiconductor switch to detect the presence of an object?
Through-Beam
What is the primary advantage of a retro-reflective photoelectric sensor?
It uses a special prism reflector to return the transmitted light in the same direction, allowing the transmitter and receiver to be housed in the same package.
How does a diffuse reflection photoelectric sensor operate?
It detects objects by measuring the diffuse reflection of light from non-smooth surfaces.
What is the Hall effect?
The generation of a voltage difference in a conductor when it is placed in a magnetic field perpendicular to the current flow.
Which type of photoelectric sensor is suitable for long-range sensing applications up to 10 meters?
Through-beam photoelectric sensor
In a mirror reflective photoelectric sensor, how is an object detected?
When the reflected beam of light from a plane surface mirror is broken.
What is the basis of Hall effect sensors?
The generation of a voltage difference in a semiconductor plate when placed in a magnetic field perpendicular to the current flow.
