The principle of an absolute encoder is fundamentally different from that of incremental encoders, for example, where only angle changes (relative values) are transmitted by the encoder. It uses a technology called Synchronous Serial Interface (SSI) to provide 24-bit resolution over just wires.

This type of multi-turn absolute encoder with battery counting, the essential core is still a single-turn absolute value, but in addition to the encoder itself, it also has an additional battery and an embedded electronic counter, which outputs the corresponding output when one revolution has passed. This is accomplished by scanning the position of a coded element. All positions in these systems correspond to a unique code.


Each code pattern forms a unique reference, and is therefore an absolute position. There is therefore no need for a reference run after switching on.


A singleturn encoder measures the absolute position within a revolution. A multiturn encoder not only provides the position within a revolution but also the number of revolutions.


As the encoder is turning, the controller is receiving counts. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made.

The absolute encoder interprets a system of coded tracks to create position information where no two positions are identical. Another feature is that absolute encoders do not lose position whenever power is switched off. The most common format for Zettlex sensors is a rotary format.


The form factor of a rotary encoder enables integration into small spaces and is particularly suited for use in direct drive frameless rotary motor control applications. Absolute Rotary Encoders.


Both absolute and incremental encoders use relatively similar technology, but an absolute encoder uses multiple bands to create a unique pattern on the disk to detect the exact position. So, there’s no need to find the home or zero position after a loss of power. AMT absolute encoder kits come with color-coded sleeves that will adapt to different motor shaft diameters.


Typical encoders on the market today only fit one motor size per sku. For example, if a manufacturer is utilizing motors with mm, mm, and mm shafts in their system, they must purchase three separate encoders.

FRABA Encoder with INTERBUS-Interface The absolute rotary encoder is a remote bus user.

The individual users are connected by an installation remote bus cable. This cable carries both the bus line coming from the master and the return line.


The connection between the rotary encoder and the bus is made by two pin connectors (male and female). An absolute encoder generates information about the position, angle, and number of revolutions in type-specific angular increment. This value is unique for every position in the whole measuring range, therefore no homing or reference traverse is required.


The transmission of the absolute values from the encoder to the control or to the servo amplifier is usually serial transmission. With absolute multiturn encoders, up to bits of unique angular positions are output per revolution. The number of revolutions is also recorded.


The unambiguous position is available even after the encoder has been disconnected from the power supply. Learn the encoder basics! More Receive the latest news about our products!
