maxim electrical components refer to devices that convert chemical energy into electrical energy, consisting of cups, tanks, or other containers or partial spaces of composite containers holding electrolyte solutions and metal electrodes to generate current. They have distinct positive and negative poles. With technological advancements, the term battery generally refers to small devices capable of generating electrical energy, such as solar cells. Key performance parameters of batteries include electromotive force, capacity, specific energy, and internal resistance. Using batteries as an energy source provides stable voltage and current, long-term stable power supply, and current minimally affected by external factors. Additionally, batteries feature a simple structure, are portable, offer easy charging and discharging operations, are unaffected by external climate and temperature, and provide stable and reliable performance, playing a significant role in various aspects of modern social life.

maxim electrical component principle

Potentiometric displacement sensors convert mechanical displacement into resistance or voltage output that has a linear or arbitrary functional relationship with the displacement via potentiometer elements. Standard linear and rotary potentiometers can be used as linear displacement and angular displacement sensors, respectively. However, potentiometers designed for displacement measurement require a definite relationship between displacement change and resistance change. The movable wiper of the potentiometric displacement sensor is connected to the measured object. The object's displacement causes a change in resistance at the moving end of the potentiometer. The magnitude of the resistance change reflects the magnitude of the displacement, while an increase or decrease in resistance indicates the direction of displacement. Typically, a supply voltage is applied across the potentiometer to convert the resistance change into a voltage output. In wire-wound potentiometers, the resistance changes in steps corresponding to the winding resistance as the wiper moves, resulting in a stepped output characteristic. If such a displacement sensor is used as a displacement feedback element in a servo system, excessive step voltages can cause system oscillation. Therefore, the resistance per turn should be minimized during potentiometer manufacturing. Another major disadvantage of potentiometric sensors is their susceptibility to wear. Their advantages include simple structure, large output signal, ease of use, and low cost.

A thermopile is a pyroelectric infrared sensor composed of thermocouples. It is widely used as a temperature detection device in applications such as ear thermometers, radiation thermometers, electric ovens, and food temperature monitoring. A thermopile consists of two or more thermocouples connected in series, where the thermoelectric potentials generated 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 these in series forms a thermopile. Depending on the application, practical thermopiles can be manufactured in wire-type and thin-film types, as well as multi-channel and array-type devices.

maxim electrical component function

Modulated pulses generated by the oscillation circuit pass through the reflection circuit, and light pulses are radiated by the LED GL. When the measured object enters the effective range of the receiver, the reflected light pulses enter the phototransistor DU. The receiving circuit demodulates the light pulses into electrical pulse signals, which are then amplified and synchronously gated and shaped. Interference is eliminated using digital integration or RC integration methods. Finally, the signal triggers the driver output (with or without delay) to produce the photoelectric switch control signal. Photoelectric switches generally exhibit good hysteresis characteristics, so slight shaking of the detected object within a small range does not affect the driver's output status, keeping it in a stable operating zone. Meanwhile, the self-diagnosis system can display the light reception status and stable operating zone to monitor the photoelectric switch's operation 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 locations such as archives, accounting departments, financial institutions, museums, and vaults are typically equipped with anti-theft devices composed of various proximity switches. In measurement technology, such as length and position measurement, and in control technology, such as displacement, speed, and acceleration measurement and control, a large number of proximity switches are also used.
