Our position angle sensor features 40mV power reverse protection and an IP66 protection rating. It delivers high vibration resistance over 20000g, with a 100Hz frequency response and an ultra-fast 0.01s response time for reliable angle measurement under harsh working conditions.
- Embedded Microprocessor for High Precision Angle Measurement: The position angle sensor adopts an embedded microprocessor combined with an arc-second CNC calibration device. It supports programmable calibration and signal conversion to deliver high-precision measurement, low temperature drift, and low power consumption.
- DSP Integrated Microprocessor with Programmable Intelligent Control: Built-in voltage & current transmitters and multiple protection circuits. Powered by DSP processing, it enables linearity correction, temperature compensation, standardized multi-range output, digital filtering, zero-point setting, and multi-segment slope customization.
- Non-contact Magnetic Sensing with MEMS Technology: Adopts MEMS technology integrating a nano magnetic flux concentration thin film and differential array magneto-sensitive components. It senses rotating magnetic field changes in a non-contact way, with reverse voltage and anti-spike voltage protection for strong anti-interference performance.
- Wear-free Non-contact Design for Extended Service Life: No mechanical contact or friction during operation. It works reliably under continuous rotation and frequent cycling in industrial applications, reducing maintenance cost and downtime.
Applications
The position angle sensor offers precise angle detection for servo motor control, valve actuators, marine, automotive, coal, textile, medical, robotic, satellite antenna, and construction machinery applications like cranes and excavators.

Installation Methods
Working Principle
Q1: Can this position angle sensor be used for valve position feedback?
A1: Yes. This position angle sensor can monitor the rotational position of valve actuators and send angle feedback to a PLC, controller, or monitoring system.
Q2: Does the sensor require mechanical contact during operation?
A2: No. This position angle sensor uses non-contact magnetic sensing, so there is no mechanical contact or friction during operation. This reduces wear on the sensing components and makes the sensor suitable for continuous rotation and frequent angle changes.
Q3: Can this position angle sensor be used in high-vibration environments?
A3: Yes. The position angle sensor provides vibration resistance above 20,000g, making it suitable for demanding applications such as construction machinery, automotive equipment, and industrial machinery.
Tips: What should I consider when choosing a position angle sensor?
Choose a position angle sensor based on your required measuring range, accuracy, resolution, output signal, supply voltage, response time, operating temperature, and protection rating. Also make sure the sensing method and output interface match your application and control system.
