Quick Answers
Learn more about industrial sensors
What are proximity sensors?
Proximity sensors detect an object's presence or absence without physically contacting the object.
Types of proximity sensors
Proximity sensors are typically split into inductive, capacitive or magnetic type proximity sensors, with inductive being the most common.
Where to use proximity sensors
Because proximity sensors detect based on their electrical interaction with the object their sensing, there are fewer effects on performance in dusty or dirty environments.
What are photoelectric sensors?
Photoelectric sensors detect objects or changes in surface conditions through a variety of optical properties.
How a photoelectric sensor works
A photoelectric sensor consists primarily of an emitter, for emitting light, and a receiver, for receiving light. When emitted light is interrupted or reflected by the sensing object, it changes the amount of light that arrives at the receiver. The receiver detects this change and converts it to an electrical output indicating whether an object is present or absent.
What is a fiber optic sensor
A fiber optic sensor is a type of photoelectric sensor that enables the detection of objects in narrow locations by transmitting and receiving light from a fiber amplifier through a fiber optic cable.
