Pixsys electrical components Germany Pixsys model Pixsys price

Pixsys electrical components refer to an electrical device that disconnects the circuit by melting the fuse element with the heat generated by itself when the current exceeds the specified value. A fuse is a current protection device made based on the principle that when the current exceeds the specified value for a period of time, the heat generated by itself melts the fuse element, thereby disconnecting the circuit. Fuses are widely used in high and low voltage distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, making them one of the most commonly used protective devices. It is an electrical device that uses a metal conductor as the fuse element connected in series in the circuit. When overload or short-circuit current passes through the fuse element, it melts due to its own heating, thereby breaking the circuit. The fuse has a simple structure and is easy to use, and is widely used in power systems, various electrical equipment, and household appliances as a protective device.

Pixsys electrical component features

(1) loudspeakers have two terminals (two leads). When a single loudspeaker is used, the two pins are not distinguished by polarity; when multiple loudspeakers are used simultaneously, the two pins have polarity distinctions. (2) The loudspeaker has a paper cone, which is usually black, but also white. (3) The shapes of loudspeakers include circular, square, and elliptical types. (4) The back of the loudspeaker paper cone is a magnet. When a metal screwdriver touches the magnet of an external magnetic loudspeaker, the presence of magnetism can be felt; there is no such feeling in an internal magnetic loudspeaker, but there is indeed a magnet inside the housing. (5) The loudspeaker is installed on the machine panel or inside the speaker box.

Pixsys electrical component performance

The performance of fiber optic connectors primarily involves optical performance, in addition to considering interchangeability, repeatability, tensile strength, temperature resistance, and number of mating cycles. 1 Optical performance: The main requirements for the optical performance of fiber optic connectors are insertion loss and return loss, which are the two most basic parameters. Insertion loss, also known as connection loss, refers to the loss of effective optical power in the link caused by the introduction of the connector. The smaller the insertion loss, the better; generally, it is required to be no greater than 0.5dB. Return loss refers to the ability of the connector to suppress the reflection of optical power in the link, and its typical value should be no less than 25dB. For connectors in practical applications, the ferrule surface undergoes special polishing treatment, which can increase the return loss, generally not lower than 45dB. 2 Interchangeability and repeatability: Fiber optic connectors are universal passive devices. For the same type of fiber optic connector, they can generally be combined arbitrarily and reused multiple times. The additional loss introduced thereby is generally within the range of less than 0.2dB. (3) Tensile strength: For finished fiber optic connectors, the tensile strength is generally required to be no less than 90N. (4) Temperature: Generally, fiber optic connectors must operate normally at temperatures between -40oC and +70oC. (5) Mating cycles: Fiber optic connectors in use can generally withstand more than l000 mating cycles.

Pixsys electrical component principle

The Hall voltage changes with the magnetic field strength; the stronger the magnetic field, the higher the voltage, and the weaker the magnetic field, the lower the voltage. The Hall voltage value is very small, typically only a few millivolts, but after amplification by the amplifier in the integrated circuit, the voltage can be amplified enough to output a stronger signal. To make the Hall integrated circuit function as a sensor, mechanical methods are needed to change the magnetic field strength. A rotating impeller is used as a switch to control magnetic flux. When the impeller blades are in the air gap between the magnet and the Hall integrated circuit, the magnetic field deviates from the integrated chip, and the Hall voltage disappears. In this way, the change in the output voltage of the Hall integrated circuit can indicate a certain position of the impeller drive shaft. Using this working principle, the Hall integrated circuit chip can be used as an ignition timing sensor. Hall effect sensors belong to passive sensors; they require an external power supply to work, which allows them to detect low-speed operation conditions.
