Coding Sensors

Encoders are used in motion feedback devices to provide position and speed information to closed-loop control systems.

• Eddy Current Linear Encoder

  (6 Suppliers)

  Eddy current linear encoders detect the distance to a target by using the magnetic field generated by a reference coil and an induction coil.

• Linear Encoder

  (42 Suppliers)

  Linear encoders detect linear movements without contact and convert them into absolute position values.

• Optical Linear Encoder

  (24 Suppliers)

  Optical linear encoders use fiber optic technology to sense position and displacement.

• Absolute Rotary Encoder

  (262 Suppliers)

  Absolute rotary encoders use optical, mechanical or magnetic indexing for angle measurement. They do not lose position after power off, but provide absolute position on power up without the need for a origin loop or any axis rotation.

• Incremental Rotary Encoder

  (81 Suppliers)

  Incremental rotary encoders are multi-turn sensors that use optical, mechanical or magnetic index counting for angle measurement. They have no absolute reference but are counted relative to the open position.

• Rotary Encoder

  (295 Suppliers)

  Rotary encoders convert the angular position of a shaft or shaft into an analog or digital code. Rotary encoders come in two types, absolute and incremental, and can be controlled by a variety of technologies, including mechanical, optical, magnetic and fiber optic.

• Rotating Position Sensors

  (174 Suppliers)

  Rotary position sensors include potentiometers, resolvers, and various magnetic and capacitive technologies for detecting angular displacement of less than one turn or displacement of multiple turns.
