In this category we present inductive proximity sensors. These devices come in many size variants, they differ in construction, parameters and application. Inductive sensors are powered by alternating or direct current. Inductive sensors are widely used in advanced automatic systems. These devices use changes in electromagnetic fields that occur as a result of the movement of special metal elements. Inductive sensors themselves generate a field which in turn causes an eddy current in the conductors. As a result, vibration parameters, such as their frequency, change. The inductive sensor is an increasingly popular element in many electronic projects. Check out Botland's offer and choose sensors for your projects!

Contactless inductive proximity sensors

Inductive proximity sensor is a component of industrial automation. This device is commonly used in production plants and in automatic devices – not only in robots, but even in production lines or in individual car subassemblies. When trying to characterize how an inductive sensor works, first of all, it must be pointed out that it is such a component that changes the state of its output after detecting a metal or magnetic object in its field.

The most common inductive sensor is a finger sensor and a cylinder sensor (as you can easily guess, it has a cylinder-shaped body with a coil end on one side, and a connection socket or cable on the other side). The coil is such a sensor detecting element. Its task is to supply power and the electromagnetic field induced around it. The introduction of metal or magnetic material there causes disturbances in the field. This in turn affects the detection of the electronics in the sensor and changes the state of its output.

There are many types of inductive proximity sensors. Due to the type of the forehead, we distinguish sensors with an open front or a closed forehead. As a rule, the former are characterized by a greater field of operation, which is the basic parameter that characterizes inductive proximity sensors. The operating range depends on the type of material that initiates the sensor.

What is an inductive proximity sensor?

Inductive sensors are most often used in industrial automation systems. These are the most common sensors among all types of proximity detectors. They are most often used in applications where it is necessary to detect the presence of a metal element in a short distance from the sensor. In this respect, inductive sensors are truly reliable. This is due to the fact that these devices are resistant to harsh industrial conditions (high temperature, unfavorable pressure). Depending on the materials from which a given sensor was produced, some detectors are resistant to chemical acids.

The most important parameters of inductive proximity sensors include the number and type of outputs. In the case of two-state sensors, the output may be in the form of a potential-free switching contact when the sensor is initiated. At this stage, it is worth distinguishing between two types of polarization - PNP polarization (supply voltage occurs at the moment of initiation) and NPN polarization (voltage close to 0 V occurs at the moment of sensor initiation).

Inductive proximity sensors with a binary output can have an output of NO (Normally Opened) and / or NC (Normally Closed) type. Additionally, it is also worth mentioning inductive proximity sensors with analog output. As a rule, the sensor is equipped with an indicator light. This option allows you to visually check whether the sensor has been initiated.

Which inductive sensor should I choose? Tough choice!

In this category, Botland has prepared for you an offer of the most commonly used inductive proximity sensors. The most popular devices are sensors with NC, NO and NO / NC switching outputs in PNP or NPN polarization. There are detectors in a cylindrical housing, with a metric thread and with nuts. The latter options make the installation of the sensors very easy. The supply voltage range is 6 V to 36V. In the case of typical automation systems, the control system supply voltage is 24 V.

For applications where a long sensor range is required, choose inductive proximity sensors with an open face with a large cross-section (diameter 30 mm and range 15 mm). Typical diameters of inductive proximity sensors are 6mm, 8mm, 10mm, 12mm, 18mm, 30mm. In Botland you will also find inductive proximity sensors that detect magnetic objects. We also invite you to familiarize yourself with the sensors integrated within the PCB (Printed Circuit Board) module with the I2C interface. Such devices are fully compatible with Arduino, Raspberry Pi, BeagleBone Wio, LinkIt ONE and other microcomputers.
