Contact sensors (potentiometers) use a physical wiper, making them cost-effective but prone to mechanical wear. Non-contact sensors use magnetic or inductive fields, offering superior longevity and reliability in high-cycle applications.
Position Sensors: Angle & Linear Measuring Component Intelligence
Precision feedback for motion control and industrial automation systems.
What are Position Sensors: Angle & Linear Measuring components?
Position sensors convert physical displacement into electrical signals for feedback loops. Choose between contact-based potentiometers for simplicity and cost, or non-contact (Hall effect, inductive) sensors for high-cycle, harsh-environment reliability.
How to Choose Position Sensors: Angle & Linear Measuring Components
Selecting the right sensor requires balancing mechanical integration with electrical interface requirements.
Measurement Range
Define the required stroke length or angular travel. Ensure the sensor's active range exceeds your mechanical limits to prevent damage.
Output Signal Type
Choose between analog (voltage/current), PWM, or digital interfaces (SSI, SPI) based on your controller's input capabilities.
Environmental Sealing
Assess IP ratings. High-vibration or dust-heavy environments necessitate ruggedized, non-contact sensing technologies.
Linearity & Accuracy
Verify the linearity error and repeatability specs against your system's tolerance requirements for precise motion control.
Mechanical Mounting
Consider the physical footprint, shaft type, and mounting hardware to ensure compatibility with existing mechanical assemblies.
