6EP1961-2BA61 electrical components are commonly used temperature-sensing elements in temperature measurement instruments. They directly measure temperature and convert the temperature signal into a thermoelectric EMF signal, which is then converted into the temperature of the measured medium by an electrical instrument (secondary instrument). The external shapes of various thermocouples often differ significantly depending on requirements, but their basic structures are largely similar. They typically consist of main components such as hot electrodes, insulating protective tubes, and terminal blocks, and are usually used in conjunction with display instruments, recording instruments, and electronic regulators. In industrial production processes, temperature is one of the important parameters that need to be measured and controlled. In temperature measurement, thermocouples are widely used due to their many advantages, including simple structure, ease of manufacturing, wide measurement range, high accuracy, low inertia, and output signals suitable for long-distance transmission. Additionally, since thermocouples are passive sensors that do not require an external power supply during measurement, they are very convenient to use and are often employed to measure the temperature of gases or liquids inside furnaces and pipes, as well as the surface temperature of solids.

6EP1961-2BA61 Electrical Component Features

(1) A loudspeaker has two terminals (two leads). When a single loudspeaker is used, the two pins have no polarity distinction; when multiple loudspeakers are used simultaneously, the two pins have polarity distinctions. (2) The loudspeaker has a paper cone, which is usually black, but can also be white. (3) Loudspeakers come in several major shapes, including circular, square, and oval. (4) The back of the loudspeaker paper cone is a magnet. With external-magnet loudspeakers, you can feel the presence of magnetism when touching the magnet with a metal screwdriver; internal-magnet loudspeakers do not produce this sensation, but there is indeed a magnet inside the housing. (5) The loudspeaker is mounted on the machine panel or inside the speaker enclosure.

6EP1961-2BA61 Electrical Component Structure

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, where the thermoelectric EMFs output by each thermocouple are superimposed. It is used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple. Connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made into wire-type and thin-film types, as well as multi-channel and array devices.

6EP1961-2BA61 Electrical Component Function

Low-power resistors are typically composed of carbon film encapsulated in a plastic housing, while high-power resistors are typically wirewound resistors, made by winding high-resistivity metal wire around a ceramic core. If a resistor's resistance value is close to zero ohms (for example, a large-cross-section wire between two points), the resistor offers no obstruction to current, and the circuit parallel to this resistor is short-circuited, resulting in infinite current. If a resistor has infinite or very high resistance, the circuit in series with this resistor can be regarded as an open circuit, with zero current. Resistors commonly used in industry fall between these two extremes; they have a certain resistance and allow a certain amount of current to pass, but the current is not as large as in a short circuit. The current-limiting function of a resistor is similar to the effect of a small-diameter pipe restricting water flow between two large-diameter pipes. Resistance, usually abbreviated as R, is a fundamental property of a conductor, related to the conductor's size, material, and temperature. Ohm's law states that I = U/R, so R = U/I. The basic unit of resistance is the ohm, represented by the Greek letter "Ω". It is defined as the resistance corresponding to a current of one ampere generated when one volt is applied across a conductor. The main function of a resistor is to impede the flow of current. In fact, "resistance" refers to a property, while "resistor" in electronic products usually refers to the component itself. Ohm is often abbreviated as Oh. Common units for expressing resistance values include kiloohm (kΩ), megaohm (MΩ), and milliohm (m Ω).
