Rotary Position Sensors

An extensive range of rotary position sensors, non contact rotary sensors and hall effect rotary sensors which offer angle measurements from 10° to 360°. We use rotary hall effect sensor, inductive and potentiometric technologies, packaged in compact or rugged housings, with environmental protection to IP68 and IP69K.

Rotary Position Sensors: Purpose & Functionality

Rotary position sensors are integrated circuits that detect an object's movement and translate its angular mechanical position to an electrical signal. Typically used in applications that require frequent adjustment, the design allows the user to control a variable output such as frequency, speed, or volume control.

A rotary position transducer features a shaftless sliding element inside, and as the object moves, it measures the displacement, resulting in movement.  

BENEFITS:

  • Extremely durable and reliable
  • Long service life
  • High precision measurement – each rotary position sensor is given an accuracy rating, which refers to its full possible rotation.  
  • Large angles of measurement – each sensor is capable of measuring a maximum angle.
  • Performs in the harshest of environments
  • Wear-free operation
  • Compact form factor
  • Cost-effective
  • Can be configured to suit specific requirements; custom sensors available
  • Intrinsically safe ATEX rotary position sensors for hazardous environments available
  • Rotary potentiometers for OEM applications (single-turn and multi-turn rotary position sensors)

Rotary Position Sensor Applications

Rotary position sensors are an ideal choice for a wide variety of industrial and non-industrial applications, such as:

  • Home appliances
  • Measurement and testing technology
  • Computers
  • Automotive industry – when used on a car, a rotary potentiometer gives measurement information from two rotating magnets to identify the rotation of its wheel.
  • Aerospace industry
  • Robotics
  • TV
  • Automation
  • Coordinate measurement
  • Gaming
  • Lighting
  • Industrial motion control
  • Machinery (e.g., for pulp and paper production)
  • Assembly and handling technology
  • Extraction technology

What angles can rotary position sensors measure?

Rotary position sensors are all different, with their specifications and possibilities. At Curtiss Wright, we provide sensors that detect rotary movement between 10° to 360°.

Types of Rotary Position Sensors

We offer several rotary position sensors ideal for individual applications. 

Rotary potentiometer

The contacting device consists of a circular track with a wiper attached to the center shaft. The component receives a consistent amount of voltage, and as the shaft rotates, the wiper remains in contact with the track. Displaying a voltage output that is related to the rotary displacement. 

Resolver

Consisting of three coils, one rotates, while the other two remain still at a 90-degree distance. All three coils receive the same amount of current, and comparing the flow between the coils determines the angular displacement of the object. 

Hall-effect sensor

A hall-effect sensor is a contactless component and works effectively in applications that function in harsher environments. It works by measuring the sensor's angular displacement and producing magnetic field changes and a difference in output voltage. While it's an excellent choice for many applications, its reliance on its magnetic field could cause interference if magnets are close to the device.
