Encoder innovator Kübler has introduced what it claims is the first optical multiturn encoder without gears and with 100% magnetic insensitivity.
The new encoder technology, developed with the Kübler Sendix F36 series, eliminates technological disadvantages such as wear and ageing or magnetic sensitivity.
The Kübler Sendix F36 series multiturn encoder supports up to 16 million revolutions
In the new patented, optimised design there is room enough only for the essentials. Even functional 'accessory parts', such as the battery – traditionally accommodated within the housing – had to give way, in order to afford extra space for the Sendix-style bearing assembly. This bearing assembly, which takes up two-thirds of the overall depth of the compact encoder, in conjunction with the non-contact optical technology in the F36 series, provides extreme ruggedness and long service life.
This is the first time that Kübler has managed to incorporate the proven Sendix ruggedness in such compact dimensions. It is probably also a record that an 8 millimetre hollow-shaft or a 10 millimetre blind-hollow shaft can be offered within the overall size of just 36 millimetres.
Reliability is enhanced by the considerable reduction in the number of component parts compared with conventional encoders – giving up the gears benefits service life and doing without a battery keeps dimensions exceptionally compact.
At the heart of the new F36 Sendix series lies a state-of-the-art OptoASIC which provides the intelligence for single turn and multiturn functions.
With a total resolution of up to 41 bits, which results from the combination of a requirement-based programmable multiturn encoder with up to 16 million revolutions and a high-precision single turn with up to 17 bits resolution, the new F36 encoders feature a wide choice of options, which opens up numerous areas of application to them.
The Kübler Sendix F36 series provides the ideal basis on which to build customer-specific solutions in demanding applications. Wherever drives need to be especially compact and economical, or in sectors that demand particularly flat solutions, such as drive engineering or medical technology, the advantages offered by the large 8 mm hollow shaft or the 10 mm blind hollow shaft become evident. The new Sendix F36 generation of encoders is set to make potentiometer solutions a thing of the past.
