Rotary Inductive Analog Sensors

WHAT IS A ROTARY INDUCTIVE ANALOG SENSOR?

TURCK’s rotary inductive analog sensor operation is based on the RLC (Resistance Inductive Capacitance) principle and incorporates an advanced microprocessor and precisely positioned emitter and receiver coils on a printed circuit board.

The emitter coils are excited with a high frequency AC field. The interaction between the moving position element and the receiver coils creates different voltages that are induced into the receiver coils which determines the position of the target.

The tuned positioning element can be mounted in a number of ways, but because it is contactless, there is no wear to the sensor or to the positioning element. Irregular rotating shafts can cause vibration and offset of the positioning element. Because of the contactless arrangement of the sensor and positioning element there is a ≤3mm compensation of lateral offset. The absence of a shaft and bearing enables easy adaption to many applications.

WHERE CAN I USE A ROTARY INDUCTIVE ANALOG SENSOR?

The rotary inductive analog sensor can be used in a variety of applications and industries.

 • Mobile equipment: Detection of the boom angle, platform rotation and ladder position.
 • Solar panel tracking and wind turbine blade pitch.
 • Commercial: Gate or door position in trains and buses.

WHY CHOOSE TURCK ROTARY INDUCTIVE ANALOG SENSORS?

TURCK Rotary Inductive Analog Sensors
