Sensors and instruments used to detect rotary position, angular position, tilt, or inclination relative to the horizon or a linear position.
Absolute Rotary Encoders (287 suppliers)
Absolute rotary encoders use optical, mechanical, or magnetic indexing for angular measurement. They do not lose their position after power-down, but instead provide absolute position upon power-up without requiring a home cycle or any shaft rotation.

Compasses (54 suppliers)
Compasses are navigational instruments that determine direction relative to Earth’s magnetic poles.

Gyroscopes (66 suppliers)
Incremental Rotary Encoders (386 suppliers)
Incremental rotary encoders are multi-turn sensors that use optical, mechanical, or magnetic index-counting for angular measurement. They contain no absolute reference, but instead count relative to the turn-on position.

Inertial Navigation Systems (81 suppliers)
Inertial navigation systems use a combination of accelerometers and angular rate sensors (gyroscopes) to detect altitude, location, and motion. They may also be capable of detecting attitude, position, velocity, temperature, or magnetic field.

Rotary Position Sensors (214 suppliers)
Rotary position sensors include potentiometers, resolvers and a variety of magnetic and capacitive technologies. Sensors are designed for angular displacement less than one turn or for multiturn displacement.
