Size & Wiring

The Garantta M18 Inductive Proximity Sensor is an M18 metal threaded cylinder with high accuracy. It uses a dedicated IC, has a long service life, and is highly reliable. The compact design of sensors can effectively save installation space and reduce mechanical damage over longer distances. The sturdy and durable design ensures less downtime and higher system throughput, making it a universal inductive sensor suitable for industrial environments. Mainly used for automatic equipment workpiece positioning, detection, and presence detection

 

Classification of M18 inductive proximity sensor

 

  • Shielded type: also called embedded type, flush type. The sides of this type of detection coil are covered with metal. Can be embedded in metal.
  • Unshielded type: The sides of this type of detection coil are not covered with metal. Compared with the shielded type, the detection distance is longer. However, since it is easily affected by the surrounding metal, you need to pay attention to the installation location.

FAQ

 

FAQ

Q: What is the main difference between shielded/unshielded M18 Inductive Proximity Sensor?

A: The main difference between the two is:

1) In terms of installation environment, the Shielded type can be embedded in metal for installation, while the non-shielded type cannot be embedded in metal for installation.

2) In terms of detection distance, the detection distance of unshielded switches is longer than that of shielded switches.

3) In terms of parallel installation, Shielded switches require installation spacing close to twice the diameter of the switch; non-shielded switches require installation spacing of 4 times the diameter of the switch.

Q: I noticed that your company's cylindrical proximity switch has a metal shell and a resin shell. What are the main differences between these two types of proximity switches?

A: There are two types of cylindrical proximity switches: metal shell and resin shell. The main differences are as follows. Metal shell type: The shell is sturdy and has a high tightening torque during installation; The installation thread (external thread) has relatively high accuracy. Resin shell type: cheaper than metal shell, generally has better water resistance. The external installation thread accuracy is relatively poor, and the tightening torque is limited.

Q: Can inductive sensors detect magnets?

A: Usually, inductive sensors cannot directly detect magnets because they mainly rely on detecting the magnetic permeability of metal objects rather than the magnetic field strength. However, if the magnet is made of magnetic metals such as iron or nickel, inductive sensors can detect it because the magnetic metal changes the sensor's magnetic field, triggering detection

Q: What is the error range of the proximity switch sensing distance?

A: The error between the sensing distance of the sensor and the standard sensing distance is generally ± 10%

Q: What is the inspection method for the M18 Inductive Proximity Sensor?

A: Inductive proximity switches belong to contactless switches (i.e., switch type sensors), which are generally used in mechanical automatic control equipment that requires high positioning accuracy, long service life, fast response speed, and easy installation. They are mainly used as limit, reset, travel positioning, counting, automatic protection, and replacement of micro switches. The detected object of the inductive proximity switch sensor must be a metal object, and for non-metallic objects, the inductive proximity switch has no action. It has the characteristics of waterproofing, shock resistance, oil resistance, dust resistance, and corrosion resistance, and has strong applicability to harsh environments.
