Hall-effect rotary position sensor designed to measure the angular position of a moving element through a magnetic field instead of a mechanical brush or a mechanical gear. This type of sensor uses a Hall-effect integrated circuit (IC) with a magnetic bias that senses the rotational movement of the actuator shaft while performing a series of operations. Rotation of the actuator shaft changes the position of the integrated circuit relative to the magnet, thereby changing the magnetic flux density, converting the output of the integrated circuit to a linear output within a 90° travel, providing feedback to the driver or vehicle subsystem.
Solid-state Hall effect technology provides non-contact operation. The magnetic field inside the sensor is used instead of the wiper used by the potentiometer. Potentiometer wipers can cause friction and reduce product life. Non-contact magnetic field Hall effect technology using a rotary position sensor not only helps reduce mechanical losses, but also reduces the execution torque, thereby extending the service life of the product.
Hall effect rotary position sensors are cost-effective and are widely used in harsh environments for transportation and industrial applications.
Potential transportation applications Foot pedal position sensing In heavy-duty equipment and other vehicles, Hall-effect rotary position sensors can replace mechanical cable connections between the foot pedal and the engine. Mechanical cables can pull or corrode and require regular maintenance and recalibration. Replacement of mechanical cables can improve engine control system response and vehicle emissions, increase reliability, and reduce overweight. This electronic throttle system is safer and more economical than the cable connection system. 
For example, a rotational position sensor can be installed adjacent to the foot pedal to measure the distance the foot pedal is depressed. The more force the driver steps on, the lower the pedal is pressed, the more fuel and air flow to the engine, and the faster the vehicle is driven. When the driver's foot releases the pedal, the Hall-effect rotary position sensor senses the change in pedal position and sends a signal to the engine to reduce fuel and air through the throttle. The vehicle will slow down in response to this signal.
Bus and Truck Suspension/Automatic Door Pedal Sensing Hall-effect rotary position sensors can also be used in bus and heavy truck ground clearance systems to sense the travel of the suspension system. The use of automatic pedals by buses can reduce their height above ground and facilitate passengers getting on and off. Hall effect rotary position sensors can be used at both ends of this application: one sensor monitors the position of the lever, and the second sensor is deployed on the suspension arm or link to monitor the ground clearance. 
Seven important questions: What are the specifications that design engineers must consider when selecting a Hall-effect rotary position sensor?
1. Durability. Engineers should consider in what type of environment the equipment will work. For extremely challenging environments, the enclosure rating of IP67 should be specified to achieve higher product durability. This is especially important for vehicles and equipment that normally operate in harsh climates and environments. 
2. Service life. The service life of the device will be clearly marked on the product data sheet. The number of rotations is preferably tested by the sensor manufacturer so that your engineering technician can save time.
3. Specify the integrated connector. The use of an integrated connector for the sensor has two important advantages. One is the smaller size and the second is a longer life. Sensors with integrated connectivity components are smaller overall package size than relying on pigtail connections, allowing developers to design and build smaller overall systems. The use of an integrated connector eliminates well-known and easily damaged pigtails and significantly improves durability because the wires in pigtails are stress-damaged, worn, and bitten or crooked by rodents.
4.EMI/EMC immunity. Radio waves of different frequencies can cause interference to electronic devices. Automotive grade EMI/EMC protection against radio frequency in the environment provides guaranteed sensor performance.
5. Standardized I/O. With industry-standard AMP terminals, 32mm mounting pitch, and universal pin layout types, you can save time, effort, and money. Standard I/O greatly simplifies plug-in replacement because its mounting point, height, and foot position are basically the same as existing devices.
6. Sensor flexibility. Before selecting a sensor, you should first determine whether you use only one type of power supply or whether you need to use multiple input voltages. Using a position sensor with multiple operating voltages or operating voltage ranges will bring you convenience. Multiple operating voltage ranges allow design engineers the flexibility to design solutions that meet the needs of different trips in many common applications.
7. Is the sensor supplier reliable? It is important that you consider whether the supplier can provide the design, testing, product quality, and customization techniques needed for the product. In addition, if suppliers are familiar with and understand international standards, as well as production/delivery processes and policies, it is even more icing on the cake.
Hall-effect position sensors designed to measure, monitor, and provide feedback are an integral part of many transportation and industrial applications. Depending on your design application, choosing the right sensor and supplier is the basis for the success of the project.
In addition to transportation applications, Hall-effect rotary position sensors can also be widely used in industrial applications.

Hall Effect Rotary Position Sensors Exert themselves in Transportation Applications
In most private vehicles or heavy industrial motor vehicles, there are a wide range of spare parts, switches and sensors, one of which is quite worthy of attention - the Hall effect rotary position sensor, which may be applied to In applications such as cars, trucks, buses and ships. Precise position sensing confirms that the vehicle is at the correct height for application system requirements, thereby improving the convenience of vehicle up and down movement. Large trailers can also use Hall-effect rotary position sensors to monitor trailer heights and increase the efficiency of docking docks. Honeywell's RTY series of Hall-effect rotary position sensors, bearing design and related IC circuit's excellent quality, make the product design life reach 15 million rotations. One of the most popular uses of Hall effect rotary position sensors is sprinkler systems for large farms. The sensor can monitor the angle range when the sprinkler is irrigating. Whether the irrigation system sprays water to the land you wish to water, or the system can reach 360 degrees. These technical knowledge can help agricultural workers reduce water consumption and increase agricultural output. One common industrial application is the control of process valves. Oilfields, nuclear power plants, food processing plants, and beverage manufacturers all need to monitor valve positions. Hall-effect rotary position sensors are used to monitor the position of large and small valves to help ensure the valve is closed or to monitor how the valve opens. Heating, ventilation and air conditioning systems can use rotary position sensors to control the bezel. On cold days, the open baffle will allow cold air to enter the room and the HVAC system will begin heating. For windows with open windows, the open baffle will also allow outdoor air to enter, reducing system efficiency and increasing heating and cooling costs. Efficient use of Hall-effect rotary position sensors and temperature sensors can help property managers better manage HVAC systems and reduce operating costs.
