AMSINDUSTRIEL electrical components Germany AMSINDUSTRIEL model AMSINDUSTRIEL price

AMSINDUSTRIEL electrical components are a common type of low-current master control device. They utilize the collision of moving parts of production machinery to actuate their contacts, thereby making or breaking control circuits to achieve specific control objectives. Typically, such switches are used to limit the position or travel of mechanical motion, enabling moving machinery to automatically stop, reverse, change speed, or perform automatic reciprocating motion according to a predetermined position or travel. In electrical control systems, the role of position switches is to implement sequence control, positioning control, and detection of position status. Used to control the travel of mechanical equipment and provide limit protection. Construction: Composed of an operating head, contact system, and housing. In actual production, limit switches are installed at pre-arranged positions. When a module mounted on the moving parts of the production machinery strikes the limit switch, the contacts of the limit switch actuate, achieving circuit switching. Therefore, a limit switch is an electrical device that switches circuits based on the travel position of moving parts; its operating principle is similar to that of a pushbutton. Limit switches are widely used in various machine tools and lifting machinery to control their travel and provide terminal limit protection. In elevator control circuits, limit switches are also used to control the speed of opening and closing car doors, provide automatic door opening/closing limit protection, and provide upper and lower limit protection for the car.

AMSINDUSTRIEL electrical component principle

Photoelectric sensors achieve control by converting changes in light intensity into changes in electrical signals. Generally, a photoelectric sensor consists of three parts: a transmitter, a receiver, and a detection circuit. The transmitter emits a light beam toward the target; the emitted light beam generally originates from semiconductor light sources, such as light-emitting diodes (LED), laser diodes, and infrared emitting diodes. The light beam is emitted continuously, or with modified pulse width. The receiver consists of photodiodes, phototransistors, and photocells. Optical components such as lenses and apertures are installed in front of the receiver. Behind it is the detection circuit, which filters out valid signals and applies them.

AMSINDUSTRIEL electrical component function

Antennas radiate radio waves and also receive radio waves. However, what the transmitter feeds into the antenna via the feed line is not radio waves, nor can the receiving antenna directly feed radio waves into the receiver via the feed line; an energy conversion process must occur in between. Below, we analyze the signal transmission process using radio communication equipment as an example to illustrate the energy conversion role of antennas. At the transmitting end, the modulated high-frequency oscillating current (energy) generated by the transmitter is input to the transmitting antenna via feeding equipment (the feeding equipment may directly transmit current waves or electromagnetic waves, depending on frequency and form). The transmitting antenna converts the high-frequency current or guided wave (energy) into radio waves—free electromagnetic waves (energy)—radiating them into the surrounding space. At the receiving end, radio waves (energy) are converted by the receiving antenna into high-frequency current or guided waves (energy), which are transmitted to the receiver via feeding equipment. From the above process, it can be seen that the antenna is not only a device for radiating and receiving radio waves but also an energy converter, serving as the interface device between the circuit and space.

AMSINDUSTRIEL electrical component principle

When current flows through a conductor, the conductor heats up due to its inherent resistance. The heat generation follows this formula: Q=I2RT; where Q is the heat generated, 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time the current flows through the conductor; from this formula, we can easily understand the simple working principle of a fuse. Once the material and shape of the fuse are determined, its resistance R is relatively fixed (if its temperature coefficient of resistance is not considered). When current flows through it, it generates heat, and the amount of heat increases with time. The magnitude of the current and resistance determines the rate of heat generation, while the construction of the fuse and its installation conditions determine the rate of heat dissipation. If the rate of heat generation is less than the rate of heat dissipation, the fuse will not blow. If the rate of heat generation equals the rate of heat dissipation, it will not blow over a considerable period. If the rate of heat generation exceeds the rate of heat dissipation, heat will accumulate. Due to its specific heat capacity and mass, this accumulation manifests as a rise in temperature. When the temperature rises above the melting point of the fuse, the fuse blows. This is the working principle of a fuse. From this principle, we should understand that when designing and manufacturing fuses, you must carefully study the physical properties of your selected materials and ensure they have consistent geometric dimensions, as these factors play a crucial role in whether the fuse operates correctly. Similarly, when using it, you must install it correctly.
