sew-eurodrive electrical components Germany sew-eurodrive model sew-eurodrive price

sew-eurodrive electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from a light source into a modulator via an optical fiber. 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 optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is introduced via the optical fiber, passes through the modulator, and is then emitted. In this process, the optical fiber first serves to transmit the light beam and second acts as an optical modulator.

sew-eurodrive electrical component parameters

The main parameters of a potentiometer include nominal resistance, rated power, resolution, sliding noise, resistance variation characteristic, wear resistance, zero-position resistance, and temperature coefficient. 1. Rated power: The maximum power allowed to be dissipated across the two fixed terminals of a potentiometer is its rated power. Note that the rated power is not equal to the power between the center tap and a fixed terminal. The rated power of a potentiometer refers to the maximum power allowed to be consumed under long-term continuous load at the specified rated temperature, when the atmospheric pressure is 87~107kPa. 2. Nominal resistance: The nominal resistance value marked on the product, with series similar to those of resistors. 3. Tolerance class: The error range between the measured resistance and the nominal resistance allows for errors of 20%, 10%, 5%, 2%, or 1% depending on the precision class. The precision of precision potentiometers can reach 0.1%. 4. Resistance variation law: Refers to the relationship between resistance change and the rotation angle (or sliding travel) of the wiper contact. This relationship can take any functional form; common types include linear, logarithmic, and reverse logarithmic (exponential). In use, linear potentiometers are suitable as voltage dividers; reverse logarithmic (exponential) potentiometers are suitable as volume controls in radios, tape recorders, phonographs, and televisions. If a replacement of the same type is unavailable during maintenance, a linear potentiometer may be used as a substitute, but a logarithmic one is not recommended. Logarithmic potentiometers are only suitable for tone control, etc.

sew-eurodrive electrical component features

A solid-state relay is a contactless electronic switch with isolation functionality. It has no mechanical contact parts during switching. Therefore, in addition to having the same functions as electromagnetic relays, solid-state relays offer compatibility with logic circuits, resistance to vibration and mechanical shock, unrestricted installation position, good moisture, mold, and corrosion resistance, and excellent performance in explosion-proofing and ozone pollution prevention. They also feature low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise, and high operating frequency. With no internal mechanical parts and a fully sealed potting structure, solid-state relays offer advantages such as vibration resistance, corrosion resistance, long service life, and high reliability. AC solid-state relays use zero-crossing triggering technology, resulting in short switching times, making them suitable for higher-frequency applications. Optical isolation is used between the input and output circuits, resulting in very low input power consumption. The output end includes protection circuits and strong load capacity.

sew-eurodrive electrical component classification

Fiber optic connectors can be divided into common single-mode and multimode connectors for silica-based fibers, as well as other types using plastic etc. as the transmission medium, based on the transmission medium. Based on the connector structure, they can be classified into: FC, SC, ST, LC, D7, DIN, MU, MT, and various other forms. Among these, ST connectors are typically used at the cabling equipment end, such as fiber patch panels and fiber modules; while SC and MT connectors are typically used at the network equipment end. Based on the fiber end-face shape, they are classified into FC, PC (including SPC or UPC), and APC; based on the number of fiber cores, they are divided into single-core and multi-core (such as MT-RJ). Fiber optic connectors are widely used and come in many varieties. In practical applications, we generally distinguish them based on the different structures of the fiber optic connectors.
