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.
