What Is a Positioning Sensor?
A positioning sensor is a sensor that measures the position of a target object and converts the position information of the object into digital information and conveys it.
There are two types of sensors: contact sensors, which grasp the position of an object by touching it, and non-contact sensors, which grasp the position of an object by emitting a laser beam toward the object. There are several types of non-contact types other than lasers.
Some displacement sensors that measure displacement, such as the amount of movement of an object, are also used as positioning sensors.
Uses of Positioning Sensors
Positioning sensors are used in all aspects of life, including medical, industrial, robotic, and infrastructure applications.
Positioning sensors can acquire one-dimensional, two-dimensional, or three-dimensional positional information, depending on the sensor. They must be used in different ways depending on the situation in which they are used.
Examples of the use of positioning sensors are as follows:
- One-dimensional information in the form of the position of the elevator cage is obtained using a contact-type positioning sensor, and the elevator stops.
- Non-contact positioning sensors measure the position of the vehicle in front in three dimensions to maintain a safe distance between vehicles and prevent collisions.
Principle of Positioning Sensors
This section describes the typical principles used in positioning sensors.
Contact type
This type of sensor measures position by direct contact of a part called a contactor with an object. This type can be used when the object is an individual.
Non-contact type
- Eddy Current Type
A high-frequency current is passed through the coil of the part called the sensor head to generate a high-frequency magnetic field, and the distance to the object is measured by the impedance change of the coil. Since the impedance is changed by electromagnetic induction, the object is limited to metal. - Phase Detection Method
A laser or other light is irradiated onto the object, and the distance to the object is calculated from the phase difference between the emitted light and the reflected light to determine the position of the object. - Triangulation Method
This method uses the triangulation method to determine the position. A laser or other light is emitted perpendicular to the object, the reflected light is detected, the distance to the object is calculated, and the position is determined. - Optical Method
Visible or infrared light is irradiated toward the object, the reflected light hitting the object and changes in light intensity are detected, and the object's position is determined. - ToF Method
The ToF (Time of Flight) method measures the time it takes for an irradiated infrared, ultrasonic, or laser light to reflect back and determine the object's position.
