anamet electrical components are a new type of contactless switching device composed entirely of solid-state electronic components. It utilizes the switching characteristics of electronic components (such as switching transistors, triacs, and other semiconductor devices) to achieve contactless and spark-free circuit connection and disconnection, hence it is also called a "contactless switch". A solid-state relay is a four-terminal active device, where two terminals are input control terminals and the other two are output controlled terminals. It has both amplification drive and isolation functions, making it very suitable for driving high-power switching actuators. Compared to electromagnetic relays, it offers higher reliability, is contactless, has a long service life, fast speed, and low external interference, and has been widely used [1].

anamet electrical components principle

A resistor consists of three parts: the resistive element, the substrate, and the leads (for solid-core resistors, the resistive element and substrate are combined into one), and only the resistive element determines the resistance value. The volt-ampere characteristic is represented by a graphical curve showing the relationship between voltage and current at the resistor terminals. When voltage and current are proportional (the characteristic is a straight line), it is called a linear resistor; otherwise, it is called a non-linear resistor. The rated power of a resistor refers to the maximum power allowed to be dissipated when the resistor works continuously at the rated temperature (maximum ambient temperature) tR. For each type of resistor, a maximum working voltage is also specified, meaning that even if the rated power is not reached, the maximum working voltage must not be exceeded when the resistance value is high. The rated power of a resistor refers to the maximum power allowed to be consumed during long-term continuous operation in DC or AC circuits. Load characteristics: When the ambient temperature is lower than tR, the resistor must not exceed its rated power; when it exceeds tR, the load power must be reduced. Each type of resistor has specified load characteristics. In addition, the allowable load is correspondingly reduced under low pressure. Under pulse load, the average pulse power is far lower than the rated power, and there are generally separate regulations.

1. Wiring harnesses are designed to facilitate installation and maintenance, ensuring that electrical equipment can operate under the harshest conditions. Wires of different specifications and colors used by various electrical equipment in the entire vehicle are reasonably arranged and integrated into one unit, with the wires bundled together using insulating materials, making them both complete and reliable. 2. Normal selection of wire cross-sectional area and color codes: ① Correct selection of wire cross-sectional area: Electrical equipment on the vehicle selects the wire cross-sectional area based on the magnitude of the load current. For electrical equipment operating for long periods, 60% of the actual current-carrying capacity of the wire can be selected; for electrical equipment operating for short periods, 60%-105% of the actual current-carrying capacity of the wire can be used. ② Selection of wire color codes: To facilitate identification and maintenance, wires in the wiring harness use different colors. For easy labeling in circuit diagrams, wire colors are represented by letters, and the corresponding colors are annotated in each circuit diagram.

anamet electrical components function

The modulated pulses generated by the oscillation circuit pass through the reflection circuit and are radiated as light pulses by the LED GL. When the measured object enters the effective range of the receiver, the reflected light pulses enter the phototransistor DU. In the receiving circuit, the light pulses are demodulated into electrical pulse signals, amplified and synchronously gated/shaped by an amplifier, and then interference is eliminated using digital integration or RC integration methods. Finally, the photoelectric switch control signal is output by triggering the driver after a delay (or without delay). Photoelectric switches generally have good hysteresis characteristics, so even if the detected object shakes within a small range, it will not affect the output status of the driver, thereby keeping it in a stable operating zone. At the same time, the self-diagnosis system can display the light-receiving status and stable operating zone to monitor the work of the photoelectric switch at any time. Proximity switches are widely used in aviation, aerospace technology, and industrial production. In daily life, they are applied in automatic doors in hotels, restaurants, and garages, as well as in automatic hot air blowers. For security and anti-theft purposes, important places such as archives, finance departments, banks, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as length and position measurement; in control technology, such as displacement, speed, and acceleration measurement and control, a large number of proximity switches are also used.
