  About the production steps of the reed switch sensor

  1. Lead wire inspection: Physical size, surface defects, and hardness inspection of nickel iron wire.

  2. Spring plate pressing: Rotate and straighten the lead wire to press it into the spring plate, press the spring plate and check its physical size, flatness, and visual defects.

  3. Degreasing: The spring leaves are degreased to remove grease and oil. There is a built-in cooling system in the production equipment to minimize steam loss.

  4. Annealing: Dry springs with oil stains removed are annealed to soften them and reduce residual magnetism. After annealing, perform residual magnetism and hardness checks

  5. Electroplating: The annealed dry spring is assembled onto the carrier and electroplated according to the required load contact specifications and differential requirements for each reed tube.

  6. Thickness measurement: Several dry appreciation electroplating samples are tested for micrometer thick precious metal electroplating, and double differential testing is used for detection.

  7. Baking: Bake the dry spring in a controlled gas. Burning and cleaning of organic matter on the surface.

  8. Reed tube sealing: Seal and automatically assemble baked reed sheets, inert gas, and pre cleaned glass tubes through equipment

  9. Lead plating: Tin plating is applied to the solderable area at the end of the yellow chip switch.

  10. Reed tube testing: Specially designed testing and manufacturing equipment ensures that all major parameters of high-quality reed tubes have been strengthened for testing. A good test result indicates that the reed tube is functioning properly during inflation and sealing processes. Any reed tubes with poor test results will be rejected and reported.

  11.Sorting: Measure the dry yellow tubes, sort them according to the required flexibility, static and variable contact resistance parameters for the application, and then package and transport them.

  “We are constantly looking to reimagine the way we use sensor technology in our everyday lives. Whether our engineers are looking at a chemical processing plant, a fighter jet or a pinball machine, we are imagining the way that we can use our products to make those technologies better.”
  
  The production of a Reed Switch requires many highly controlled process steps from Stamping to Sputtering to hermetic sealing done in Clean Rooms that comes from years of experience in the Reed Switch business. The following are the list of steps used in our production process.
  
  Reed switch production involves a tightly controlled flow of process steps to ensure the optimal functionality and reliability of the final product. The processes are meticulously followed to manufacture high-quality reed switches that can be used in various industries such as automotive, telecommunications, and home appliances.
  
  The production flow of a reed switch begins with the preparation of the basic raw materials, the reed blades. Blades are pressed from specially-selected alloys that possess desirable magnetic properties. The alloy is carefully chosen based on factors such as corrosion resistance, durability, and sensitivity to magnetic fields and matching coefficient of thermal expansion with the glass tube. Once the alloy is obtained, it is then pressed into thin, flexible reed blades through precision stamping. These blades are crucial as they act as the switch contacts.

  After the reed blades are prepared, the next step in the production process is the cleaning and assembly. The blades are thoroughly cleaned to remove any impurities by degreasing,  that could impact their performance. Then they go through a controlled annealing process to remoe any work hardening that came along with the stamping.

  
  

  After this, the blades are loaded on to special jigs and taken for sputtering. The chamber is evacuated by a cryogenic pump to approximately satellite level vacuum of space and a proprietary multi-layer Ruthenium coating is done using a water cooled Magnetron and 99.95% purity Ruthenium target. The sputtered blades are then baked out to burn off an surface impurities.

  
  

  Then the reed blades are aligned on the production heads, and are encapsulated within a glass tube to provide electrical insulation and protection from external elements. The glass tube is carefully selected to maintain the desired dimensions and is sealed to prevent any moisture or dust from entering. This step is critical to ensure the longevity and reliability of the reed switch.

  
  

  Following encapsulation, the reed switch goes through a series of quality control tests. These tests evaluate various parameters such as contact resistance, operating AT, and sensitivity to magnetic fields. Only the switches that meet the predetermined specifications are approved for further processing, while any non-conforming switches are rejected.

  
  

  Finally, the approved reed switches undergo a final inspection, packaging, and labeling before they are ready for shipment to customers. The packaging process ensures proper protection during transportation, while labeling provides essential information for identification and usage. Reed Switches are also usedin the production of Reed Sensors, Magnet Sensors and Thermal Cut outs.

  
  

  The production flow of reed switches involves a well-defined process that includes raw material preparation, cleaning, assembly, encapsulation, quality control tests, and final packaging. Following this flow meticulously ensures the production of reliable and high-quality reed switches that fulfill the requirements of various industries.

  The Application of reed switches in Industry
  

  The reed sensor, in combination with a wide range of programmable logic controllers (PLCs) and microcontrollers, has a high operating speed. When using a weak magnet, the dry spring sensor can also detect.

  Any metal part containing iron.

  
  
  

  Safety oriented application of reed tubes

  Fiber optic sensor lenses require exceptionally clean guidance for sensing applications- A magnetic spring switch and magnet are combined into a component with a specific distance, forming a (NC) normally closed circuit between them

  Reed sensor. When the permanent magnet reaches between them, the magnetic field begins to branch and the magnetic spring switch opens. (NO) Normally open reed sensors can be designed to use a normally closed magnetic spring on one side.

  Install a magnet on the other side of the switch to ensure that the normally closed reed switch is open. Based on magnetic spring switch sensors, they can operate in very dirty industrial environments without being affected by grease and dust.

  Work. Common applications include sensing of conveyor belts and speed sensing of industrial mixers.

  
  

  Sensing at the end position of the cylinder and piston

  Most cylinders, pistons, linear sliding and rotating actuators generate end position sensing with built-in magnets. The reed sensor is used to sense the position of the end and the middle position, and the signal can be detected

  Further instruction on the application of PLC. The reed sensor works in conjunction with the PLC program with a very high detection speed and scanning speed. The dry spring sensor can also be equipped with an indicator light (emitting diode).

  The pole tube is used to assist in adjusting the angle of the piston and cylinder body stroke or rotating actuator after easy positioning.
