The principle of operation of the proximity switch
The function of the proximity switch is that when an object is close to the proximity switch and reaches a certain distance, it can announce the signal. It does not require external force to be applied and is a contactless master appliance. It is far more useful than the travel switch, with stroke control and limit maintenance. Proximity switches can be used for high-speed counting, metal body detection, speed measurement, liquid level control, part size detection, and as a contactless button.
Now it is widely used, and the proximity switch can be divided into the following types according to the operating principle: high-frequency oscillation type: detection of various metal body capacitance type: detection of various conductive or non-conductive liquid or solid photoelectric type: detection of opaque substances Ultrasonic type: detection of non-permeable ultrasonic materials Electromagnetic induction type: detection of magnetic or non-magnetic conductivity metals can be divided into garden column type, square type, ditch type, perforation (through) type and separation type according to its appearance and shape. The garden column type is easy to install than the square type, but its detection characteristics are the same, the groove type detection part is the inside of the groove, used to detect the object in the tank, through type China is rarely produced, and Japan is more commonly used, can be used for small screws or balls and other small parts and buoys assembled into water level detection equipment. The proximity switch can be divided into according to the power supply mode; DC type and communication type, according to the output type, can be divided into DC two-wire system, DC three-wire system, DC four-wire system, communication two-wire system and communication three-wire system.

Precautions when switching the ifm on or off the power supply
The output status of the sensor when the power is turned on or off, whether it is detected or not, is OFF. In particular, when the power supply is turned on, the output condition is OFF for a certain period of time is called the initial reset. But in the following cases, the output will be momentarily ON(OFF) ...

Common faults in ifm encoders
1. Encoder own problem: It refers to the problem of the encoder's own components, resulting in its inability to generate and output correct waveforms. In this case, the encoder needs to be replaced or its internal components repaired.
2. Encoder connection cable problem: the probability of this problem is high, and the maintenance is under repair.

The function and purpose of ifm pressure sensors
Pressure sensors are one of the more common sensors. Conventional pressure sensors are primarily mechanical devices, and the deformation of elastic parts indicates pressure. However, due to their size and weight, they are unable to generate electricity. The development of semiconductor skills has also led to the emergence of semiconductor pressure sensors.

High-frequency pressure sensor output signal – ifm
The conversion of the pressure to the electrical signal is done by the physical deformation of the strain gauge, and the strain gauge is bonded to the diaphragm of the pressure sensor and wired into a Wheatstone bridge structure. The pressure exerted on a high-frequency pressure sensor causes the diaphragm to flex, which causes the strain gauge to strain. Strain will occur ...
