What is a photoelectric sensor? Why do photoelectric sensors need potting materials?

In modern automation and industrial control systems, photoelectric sensors are widely used in various detection and control fields as a key component. photoelectric sensors play an irreplaceable role whether in automatic door switch detection or object recognition on the production line, However, due to the complex and diverse application environments, photoelectric sensors need to rely on potting materials to improve their durability and reliability. What is a photoelectric sensor? Photoelectric sensors detect objects, changes in surface conditions, and other items through a variety of optical properties. A photoelectric sensor is mainly composed of an emitter for emitting light and a receiver for receiving light. When the emitted light is blocked or reflected by the sensing object, the amount of light reaching the receiver changes. The receiver detects this change and converts it into an electrical output. The light source for most photosensors is infrared or visible light (usually red, or green/blue for color recognition). Photoelectric sensors often face various harsh environmental conditions in practical applications, including high temperature, moisture, dust and mechanical vibration. In order to protect the precise electronic components inside the photoelectric sensor and extend its service life, potting materials are particularly important. The main functions of potting materials include: 1. Waterproof and dustproof: Protect the sensor from moisture and dust to ensure its normal operation in harsh environments. 2.Anti-vibration: Provides mechanical strength and reduces the impact of external vibrations on the sensor. 3.High temperature resistance: Maintain stable performance in high temperature environments to ensure the accuracy and reliability of the sensor. 4.Anti-corrosion: Resist corrosion of the sensor by chemical substances and extend its service life.

Elaplus automobile liquid level sensor potting solution

In the modern automotive industry, fluid level sensors play a vital role. They are widely used in the monitoring and control of various liquids such as fuel tanks, water tanks, coolant tanks, etc. to ensure that vehicles can operate normally under various working conditions. However, since cars drive in different environments, the liquid level sensor needs to withstand harsh conditions such as high temperature, humidity and vibration. In order to improve the reliability and service life of the liquid level sensor, it is particularly important to choose the appropriate potting compound. Solution Fluid level sensors are often exposed to various harsh environments, such as high temperatures and high humidity in engine compartments, or extreme low temperatures in cold regions. As a key protective material, potting material can effectively encapsulate the electronic components inside the sensor to prevent them from being affected by the external environment. The main functions of potting material include: 1. Waterproof and dustproof: Protect the internal components of the sensor from the intrusion of moisture and dust. 2. High temperature resistance: Ensure that the sensor can still work stably in high temperature environments. 3. Anti-vibration: Provide mechanical strength to prevent damage to the sensor from vibration and impact. 4. Anti-corrosion: Resist corrosion of the sensor by chemical substances. Recommended Products

Elaplus Line Light Overall Adhesive Application Solution

Line lights, also known as linear lights, are a type of lamp widely used in lighting design. They are characterized by the ability to form a continuous light strip when installed, creating a smooth, modern lighting effect. However, to ensure the long-term stability and excellent performance of linear lights, it is essential to use the right glue and encapsulation . Challenges of adhesive for line lights Although glue is essential in the installation and maintenance of line lights, there are still some challenges to overcome: 1.Environmental adaptability: Outdoor linear lights need to withstand various harsh weather conditions, and the glue must have a high degree of weather resistance and temperature resistance. 2.Bonding strength: Different parts of the linear light require different bonding strengths, and choosing the right glue to ensure a solid connection between the components is a challenge. 3.Transparency requirements: Especially for the bonding of glass cover plates, the glue needs to have good transparency to ensure that light is not obstructed. 4.Electrical protection: Power potting requires glue to provide good insulation performance, and also has to have a certain thermal conductivity to dissipate heat.

Elaplus internal potting of vortex sensor

The vortex sensor is a non-contact sensor based on the principle of electromagnetic induction. It is widely used in industrial automation, aerospace, automobile manufacturing and other fields to measure the position, speed, vibration and other parameters of metal objects. vortex sensors have become an important tool in the industrial field due to their high accuracy, fast response, and good stability. How Vortex Sensors Work? The working principle of vortex sensors is based on Faraday’s law of electromagnetic induction. When the coil in the sensor is energized, an alternating magnetic field is generated around it. When a metal object approaches the sensor, the alternating magnetic field generates vortex on the metal surface. These vortex will form a reverse magnetic field inside the metal, affecting the distribution of the original magnetic field. The sensor detects these changes and then calculates the position, speed and other parameters of the metal object. Advantage Of Vortex Sensors 1.High precision: Vortex sensors can provide micron-level measurement accuracy and are suitable for precision measurements. 2.Non-contact measurement: The vortex sensor has no direct contact with the object being measured and will not cause wear or damage to the object being measured. 3.Fast response: The vortex sensor has a fast response speed and can detect dynamic changes in real time. 4.Resistant to harsh environments: vortex sensors can work stably in harsh environments such as high temperature, high pressure, and oil pollution. Application Vortex sensors are widely used in many fields: Industrial automation: used for real-time monitoring and control of parameters such as position, distance, vibration, etc. Aerospace: used for condition monitoring of key components such as aircraft engines and turbines. Automobile manufacturing: used for testing body, engine and other components to ensure production quality. Machine tool equipment: used for real-time monitoring during processing to improve processing accuracy and efficiency….

Adhesive and potting materials for end caps of automotive oil filters

If the seal of the end cap is not good, the oil may leak out from the joint between the end cap and the filter element or the housing, which will not only lead to the loss of oil, but also may affect the normal operation of the engine. In addition, the stability of the end cover also affects the overall structure and performance stability of the filter. If the end cap is loose or falls off, it may lead to the structural deformation of the filter, and even affect the filtration efficiency of the filter.
