AutomationX electrical components Germany AutomationX model AutomationX price

AutomationX electrical components are current fuses that provide overload protection. When a circuit fault or abnormality occurs, the current continues to rise. This rising current may damage certain important devices in the circuit, burn out the circuit, or even cause a fire. If a fuse is correctly installed in the circuit, it will melt and cut off the current when the current abnormally rises to a certain level and temperature, thereby protecting the safe operation of the circuit. With the fuse correctly installed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain level and temperature, protecting the safe operation of the circuit. The fuse invented by Edison was used to protect the then-expensive incandescent lamps. With the development of the times, fuses protect power equipment from damage due to overcurrent and overheating, avoiding serious damage to electronic equipment caused by internal faults.

AutomationX electrical component classification

1, fusible resistor: also called a fuse resistor, it serves the dual function of a resistor and a fuse under normal conditions. When a circuit fault causes its power to exceed the rated power, it melts like a fuse to disconnect the connected circuit. Fusible resistors generally have small resistance values and low power ratings. 2, sensitive resistor: refers to a resistor whose resistance value is sensitive to a certain physical quantity (such as temperature, humidity, light, voltage, mechanical force, and gas concentration). When these physical quantities change, the resistance value of the sensitive resistor changes accordingly, presenting different resistance values. According to sensitivity to different physical quantities, sensitive resistors can be divided into types such as thermistors, humidity-sensitive resistors, photoresistors, varistors, force-sensitive resistors, magnetoresistors, and gas-sensitive resistors. The materials used for sensitive resistors are almost all semiconductor materials, so these resistors are also called semiconductor resistors. The resistance value of a thermistor changes with temperature; a thermistor whose resistance decreases as temperature rises is a negative temperature coefficient (NTC) thermistor. NTC thermistors are widely used and can be further divided into general-purpose NTC thermistors, voltage-stabilizing NTC thermistors, and temperature-measuring NTC thermistors. The resistance value of a photoresistor changes with the intensity of incident light; when the incident light increases, the resistance of the photoresistor decreases, and when the incident light weakens, the resistance value increases.

AutomationX electrical component applications

Photoelectric sensors that use photoelectric elements as sensitive elements come in many types and have wide applications. According to the nature of the output of photoelectric sensors, they can be divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent can be used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. For example: illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ellipticity, and surface roughness of processed parts, all of which use photoelectric elements as their sensitive elements. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Devices that convert the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements are used as switching photoelectric conversion elements. For example, photoelectric input devices for electronic computers, switching temperature regulation devices, and digital photoelectric tachometers for speed measurement.

AutomationX electrical component characteristics

The so-called dynamic characteristic refers to the output characteristic of a sensor when the input changes. In practical work, the dynamic characteristic of a sensor is often expressed by its response to certain standard input signals. This is because the sensor's response to standard input signals is easy to obtain through experimental methods, and there is a certain relationship between its response to standard input signals and its response to arbitrary input signals; often, knowing the former allows one to deduce the latter. The most commonly used standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of sensors are also often expressed by step response and frequency response.
