Description
Technical Parameters
Size & Wiring

M8 inductive sensor uses the mutual induction principle of metal conductors and alternating electromagnetic fields. The detection coil located at the front end of the sensor generates a high-frequency magnetic field. When a metal object approaches the magnetic field, eddy currents are generated inside the metal object, causing the magnetic field energy to attenuate. When the metal object continues to approach the sensing surface of the sensor, the energy is absorbed and attenuated. When the attenuation reaches a certain level, the sensor switch is triggered to output a signal, thereby achieving the purpose of non-contact detection.

Advantages of m8 inductive sensor

 

  • Durable and reliable: usually encapsulated in sturdy materials (metal or high-performance plastic), capable of withstanding harsh industrial environments (impact, vibration).
  • High precision and high resolution: capable of accurately detecting micrometer-level displacement changes of metal targets (especially analog output type), providing stable position feedback.
  • Non-contact measurement: This is the most essential feature, as there is no physical contact between the sensor and the metal target being measured, and detection is carried out through electromagnetic induction. It has no friction or wear, extending the life of the sensor and the measured object itself. No mechanical load will affect high-speed or light objects being measured.
  • Only sensitive to metals: can only detect conductor materials (mainly metals). Does not react to non-metallic materials such as plastic, wood, paper, and the human body.

FAQ

Q: What fields can M8 Inductive Sensor be used in?

A: Inductive sensors exist in machinery such as machine tools, the textile industry, the automotive industry, assembly lines, etc. They are used to detect metal parts in harsh environments and to inspect metal components when fast-moving parts need to be inspected.

Q: How to choose a proximity sensor?

A: When choosing a proximity sensor, it is helpful to be aware of the following questions: What are the properties of the detected object: solid, liquid, particle, metal, etc? What is the distance between the sensor and the object? What is the shape of the object being detected?

Q: Why choose M8 Inductive Sensor?

A: Inductive proximity sensors have the highest sales volume. They have an oscillating circuit that generates an electromagnetic field. Any metal part that approaches it will be detected because it is the source of induced current, thereby reducing the oscillation detected by the detector. 

The main characteristics of inductive sensors are: Can only be used for metal parts Relatively limited range: up to 80 millimeters, varying according to the properties of the alloy Low cost: half the price of photoelectric sensors Durable and sturdy, able to withstand harsh environments, insensitive to impacts, vibrations, dust, etc A higher switching frequency (several kHz) allows for the detection of components passing at high speeds even during rotation. Excluding easily worn moving parts

Q: What is the principle of the M8 Inductive Sensor?

A: Inductive sensors consist of three main parts: an oscillator, a switch circuit, and an amplifier output circuit. The oscillator generates an alternating magnetic field. When the metal target approaches this magnetic field and reaches the induction distance, eddy currents are generated inside the metal target, leading to oscillation decay, reducing or even stopping vibrating. The changes in oscillator oscillation and stop oscillation are processed by the post-amplification circuit and converted into switch signals, triggering the driving control of Manufacturing devices to achieve non-contact detection purposes.

Q: What are the differences between embedded and non-embedded installation methods?

A: The installation method is also a factor to consider when selecting. This type of sensor offers two installation methods: embedded and non-embedded. The buried installation method is suitable for metal object detection, and its side design has taken into account metal shielding, which is not affected by the side metal. For non-embedded models, side clearance needs to be considered, and their sensing distance is usually greater than that of ordinary embedded models. In practical applications, the appropriate installation method should be selected based on specific installation requirements.
