insys electrical components are sensors that convert the state of a measured object into measurable optical signals. The operating principle of a fiber optic sensor is to guide the light beam from a light source via an optical fiber into a modulator. Inside the modulator, interaction with external measured parameters causes changes in the optical properties of the light, such as intensity, wavelength, frequency, phase, and polarization state, resulting in a modulated optical signal. This signal is then transmitted via the optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is guided through the optical fiber, passes through the modulator, and is then emitted. The primary role of the optical fiber is to transmit the light beam, and its secondary role is to act as an optical modulator.

insys electrical component classification

1. Classified by operating nature into transmitting antennas and receiving antennas. 2. Classified by application into communication antennas, broadcast antennas, television antennas, radar antennas, etc. 3. Classified by directionality into omnidirectional antennas and directional antennas, etc. 4. Classified by operating wavelength into ultra-long wave antennas, long wave antennas, medium wave antennas, short wave antennas, ultra-short wave antennas, microwave antennas, etc. 5. Classified by structural form and operating principle into wire antennas and aperture antennas, etc. Characteristic parameters describing antennas include radiation pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization, and bandwidth. 6. Classified by dimensionality into two types: (1) One-dimensional antennas consist of many wires, which may be straight lines like those used in mobile phones, or clever shapes like the old "rabbit ear" antennas used on televisions before cable TV. Monopole and dipole antennas are the two most basic one-dimensional antennas. (2) Two-dimensional antennas: Diverse variations, including patch (a square piece of metal), array (an organized two-dimensional pattern of patches), horn, and dish types. 15. Antennas can be classified into three major categories based on usage scenarios: handheld transceiver antennas, vehicle-mounted antennas, and base station antennas. Handheld transceiver antennas are antennas for personal use with handheld two-way radios, commonly divided into rubber antennas and telescopic whip antennas. Vehicle-mounted antennas refer to communication antennas originally designed for installation on vehicles; the most common and widely used type is the magnetic mount antenna. Vehicle-mounted antenna structures also include shortened types, quarter-wave, center-loaded, five-eighths wave, and half-wave dipole configurations. Base station antennas play a critical role in the entire communication system, especially at communication hubs acting as central stations. Common base station antennas include fiberglass high-gain antennas, four-loop array antennas (eight-loop array antennas), and directional antennas

insys electrical component performance

1. Protection characteristics: When the surge strength from the surge source does not exceed the specified value, the clamping voltage of the varistor must not exceed the impulse withstand voltage that the protected object can endure. 2. Surge withstand characteristics: The varistor itself must be able to withstand the specified surge current, surge energy, and the average power when multiple surges occur sequentially. 3. Life characteristics have two aspects: one is the continuous operating voltage life, meaning the varistor should reliably operate for a specified time (in hours) under specified ambient temperature and system voltage conditions. The other is surge life, meaning it can reliably withstand a specified number of surges. 6. After the varistor is integrated into the system, in addition to its "safety valve" protection function, it introduces some additional effects, known as "secondary effects," which should not degrade the normal operating performance of the system. The main factors to consider are threefold: first, the inherent capacitance of the varistor; second, the leakage current under system voltage; and third, the influence of the varistor's nonlinear current coupling through the source impedance on other circuits.
