How to determine the reasonable radiation intensity and collector current for the photoelectric sensor The output current of the photoelectric sensor is a very critical performance parameter of the photoelectric sensor. The output current of the photoelectric sensor is not only related to the design parameters such as the radiation intensity of the transmitter and the collector current of the receiver

Huawei is blocked by the United States In fact, Pepperl+Fuchs is a role model for progress! As a leading electronics company in China, Huawei has always been favored by the world. It also wants to enter the US market

Identification of photoelectric switch NPN and PNP The photoelectric switch can be divided into two states: NPN output and PNP output. When there is a current flowing out of the sensor (PNP output type), the current flows from the power supply through the output of the sensor to the load, and then to the ground.

Imported high quality Pepperl + Fux sensors Pepperl+Fuchs photoelectric sensor is one of P+F's automation equipment products. The important features are: long detection distance, no strict detection limit, relatively short response time, non-contact detection, and high resolution .

Inductive proximity switch from the structure can be divided into several categories Inductive proximity switches can be divided into many types according to the type of structure. The more common ones are self-controlled switches, which can amplify the circuit and signal to drive the circuit and power supply. Because this inductive switch connects the relay and each

Inductive proximity switch work to pay attention to what points In the process of using the inductive proximity switch, we must pay attention to its anti-vibration and impact resistance. This is the key to affecting the service life of the proximity switch. Once the shock wave is too large or frequent vibration occurs,

Infrared Photoelectric Switch The important function of the infrared photoelectric switch is to be able to deal with the change of light intensity: use optical elements to change the light beam in the middle of the propagation medium; use the light beam to reflect the object; make the light beam return instantaneously after a long distance.

Installation and use of photoelectric switch During the installation or use of the photoelectric switch, due to the influence of the workbench or the background and the use of vibration, it sometimes causes problems such as slight deviation of the optical axis, lens stains, dust accumulation, external noise, and out-of-range ambient temperature.

Introduction of photoelectric switch application process (a) The photoelectric switch is used to control the positioning and shearing of the material;

Introduction of photoelectric switch detection scheme Detection is to use physical methods to identify the number of measurement parameters in a certain range to determine whether the measurement parameters are qualified or whether there is a number of measurement parameters.
