From national standard development to real-world applications, SANQIAOHUI is committed to advancing magnetic sensing technology for HVAC systems, commercial ice machines, swimming pool equipment, and robotics.
SANQIAOHUI (Sanqiaohui (Foshan) New Materials Co., Ltd.) is pleased to share its participation as one of the drafting organizations of China's national standard GB/T 47563-2026, Micro-electromechanical systems (MEMS) technology—Technical specification of MEMS magnetic field sensor.
As magnetic sensors become increasingly important in modern equipment, our focus remains on helping customers identify suitable sensing solutions for their specific products, operating environments, and control requirements.
Micro-electromechanical systems (MEMS) integrate mechanical structures and electronic functions at a microscopic scale. MEMS magnetic field sensors are designed to detect magnetic fields and convert magnetic-field changes into electrical signals that can be processed by electronic control systems.
These sensors can support a wide range of functions, including position detection, proximity sensing, equipment status monitoring, and contactless switching, depending on the sensor design and system configuration.
The publication and implementation of GB/T 47563-2026 establish a national standard reference for MEMS magnetic field sensor technology.

Drafting organization: Sanqiaohui (Foshan) New Materials Co., Ltd., among the listed drafting organizations
By participating in the development of this standard, SANQIAOHUI contributes to collaborative industry efforts in technical standardization and supports the continued development of the magnetic sensing industry.
The standard should be distinguished from individual product certifications: the publication of a national standard does not automatically certify every magnetic sensor or product supplied by a participating organization.
Heating, ventilation, and air conditioning (HVAC) systems rely on reliable sensing and control to maintain operating conditions and protect equipment.
Magnetic sensors and magnetic switches can be used in suitable HVAC designs for functions such as position detection, cover or component status monitoring, and contactless switching.
Potential application areas include:
Condensate overflow protection: Magnetic switching technology may be incorporated into compatible float-switch designs to help detect rising condensate levels.
Equipment status detection: Magnetic sensors can detect the position or state of selected moving components when paired with an appropriate magnetic target.
Contactless switching: Magnetic activation can reduce the need for direct mechanical contact in suitable sensing arrangements.
System integration: Sensor selection can be tailored to the installation environment, electrical interface, mounting method, and control requirements.
SANQIAOHUI provides sensor-related products and technical support for HVAC and refrigeration applications. Our goal is to help OEMs, distributors, and replacement-parts suppliers identify practical solutions for equipment monitoring and control.
Commercial ice machines operate through coordinated water filling, freezing, harvesting, and storage processes. Reliable sensing is essential to support equipment control and operating-state detection.
Depending on the system architecture, magnetic sensors and magnetic switches may be used in applications such as:
Ice bin level or door status detection: Magnetic switching arrangements can detect the position of a compatible door, flap, or moving component.
Component position sensing: Contactless magnetic detection can provide position information to an electronic control system.
Equipment interlocks: A magnetic switch can be incorporated into a suitable design to indicate whether a selected component is in the required position.
Maintenance and replacement: Compatible replacement sensors and switches can help service providers maintain existing equipment.
Sensor selection depends on the original equipment design, magnetic target, sensing distance, electrical characteristics, mounting location, and operating environment.
SANQIAOHUI focuses on practical sensing components for commercial appliance and ice machine applications, helping customers identify replacement and OEM solutions based on their technical requirements.
Swimming pool equipment, salt chlorination systems, water circulation systems, and pool heaters use different sensing technologies to monitor operating conditions and support safe equipment control.
Magnetic sensing can be useful where a system requires contactless position detection or magnetic switching. However, magnetic sensors should not be confused with all types of pool flow sensors: actual flow detection depends on the sensing mechanism and the specific product design.
Potential magnetic sensor applications include:
Equipment position monitoring: Detecting the position of selected moving components.
Contactless switching: Providing a switching signal when a magnetic target reaches a defined position.
Control-system integration: Supplying a sensor signal to a compatible electronic controller.
Water-equipment service: Supporting the maintenance of compatible sensing and switching assemblies.
For pool and water equipment, sensor selection must take into account moisture exposure, sealing, connector protection, temperature, electrical compatibility, and the manufacturer's installation requirements.
SANQIAOHUI serves the pool, spa, and water-equipment markets with sensor-related products designed for specific equipment and application requirements.
Robotics and industrial automation increasingly depend on accurate information about position, movement, and operating state.
Magnetic sensing offers a contactless approach that can be useful in selected robotic and automation designs. Depending on the sensor technology and system architecture, potential applications include:
Position feedback: Detecting the position of a moving component or magnetic target.
Joint and actuator monitoring: Supporting position detection in compatible mechanical assemblies.
Proximity detection: Identifying the presence of a magnetic target within the designed sensing range.
Compact equipment integration: Enabling sensing in applications where a contactless solution is beneficial.
Robotic applications can impose demanding requirements for accuracy, response time, temperature stability, electromagnetic compatibility, vibration resistance, and service life. The appropriate sensor must therefore be selected and validated for the intended operating conditions.
As magnetic sensing technology develops, SANQIAOHUI sees opportunities to support customers exploring new sensor applications in automation and intelligent equipment.
