The difference between wiring harness and sensors and their wide applications

1、 The difference between wiring harness and sensor 1. Definition and Function Wire harness: A wire harness is a set of connecting components that bind wires, cables, terminals, connectors, etc. together to carry signals and power between devices. It is mainly composed of wires and cables, connectors, terminals, and other auxiliary materials (such as tape, zip ties, sleeves, etc.), used to transmit power and signals in electrical systems. Sensor: A sensor is a detection device that can sense the measured information and convert it into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. Sensors typically consist of three parts: sensitive components, conversion components, and measurement circuits, and are widely used in fields such as industrial automation, environmental monitoring, and medical equipment. 2. Structural differences Wire harness: The structure of a wire harness is relatively simple, mainly composed of wires, cables, and connectors. The wires and cables are responsible for transmitting power and signals, while the connectors are used to connect different electrical equipment. The design of wiring harnesses needs to consider factors such as the specifications of wires and cables, environmental adaptability, temperature range, as well as the type and performance of connectors. Sensor: The structure of a sensor is relatively complex, usually consisting of three parts: sensitive components (such as resistors, capacitors, inductors, etc.), conversion components (such as semiconductor devices, transistors, etc.), and measurement circuits. Sensitive components are responsible for sensing the measured information, conversion components convert the sensed information into electrical signals, and measurement circuits amplify, filter, and process the converted electrical signals. 3. Application Fields Wiring harness: Wiring harness has a wide range of applications, covering almost all occasions that require power and signal transmission. From household appliances to industrial equipment, from automobile manufacturing to aerospace, wiring harnesses are indispensable components. Sensors: Sensors have a wide range of applications, but they are more focused on measuring and monitoring specific physical or chemical quantities. In industrial automation, sensors are used to detect parameters such as temperature, pressure, and flow rate; In environmental monitoring, sensors are used to detect environmental indicators such as air quality and water quality; In medical devices, sensors are used to monitor the vital signs of patients. 2、 Wide application of wire harness 1. Automotive industry Automotive wiring harness is the main network component of automotive circuits, closely related to electronic control systems. With the increasing functionality of automobiles and the proliferation of electrical components, wiring harnesses are playing an increasingly important role in automotive manufacturing. The automotive wiring harness includes two types: power lines that carry power for driving and executing components, and signal lines that transmit sensor input commands. Advanced automobiles have introduced CAN bus configuration and multi-channel transmission system to reduce the number of wires and connectors, making wiring easier. 2. Information communication In the field of information and communication, wire harnesses are used to connect various electronic devices such as switches, routers, servers, etc. The data transmission and power supply between these devices cannot be separated from the support of wiring harnesses. With the rapid development of technologies such as 5G and the Internet of Things, the application of wire harnesses in the field of information and communication will become more widespread. 3. Photovoltaic energy storage In photovoltaic energy storage systems, wiring harnesses are used to connect components such as solar panels, inverters, and energy storage batteries. The power transmission and signal communication between these components rely on wiring harnesses. With the increasing global attention to renewable energy, the market size of photovoltaic energy storage systems continues to expand, and the application of wiring harnesses will also increase accordingly. 4. Household appliances In household appliances, wiring harnesses are used to connect power and signal lines to devices such as televisions, refrigerators, and washing machines. The power transmission and signal communication between these devices cannot be separated from the support of wiring harnesses. With the continuous development of smart home technology, the application of wiring harnesses in household appliances will become more intelligent and convenient. 5. Industrial automation In the field of industrial automation, wire harnesses are used to connect various sensors, actuators, controllers, and other equipment. The data transmission and power supply between these devices rely on wiring harnesses. With the introduction of concepts such as Industry 4.0 and intelligent manufacturing, the application of wire harnesses in industrial automation will become more extensive and in-depth.
