Absolute Encoder
Absolute encoders are position feedback devices that report absolute positional information. An absolute encoder generates a unique code for each position. Absolute encoders do not lose position when power is removed. Since each position is unique, true position verification is available as soon as power is up. It is not necessary to initialize the system by returning to home base.
- Single-turn Absolute Hollow Shaft Encoder
A hollow shaft encoder is one of the most common shaft designs because of its versatility. Instead of having a solid bar that has to match the motor, a hollow shaft encoder fits over the motor shaft and is then clamped in place. It's held in position by a flexible tether. This means that a hollow shaft encoder does not have to be perfectly sized to fit the motor and it does not require any external components which increase its size. A hollow shaft encoder also has a more forgiving installation; the clamp and the tether can be used to adjust the position and to absorb shocks and vibration that could cause misalignment.Hollow shaft encoders are available in two configurations: through-shaft and blind-shaft.
