Single-turn Absolute Encoder A/9115S

Q: What protocol does the A/9115S SSI interface use?

An external clock controls the data output: the position value is first stored in the encoder and transmitted starting with the most significant bit (MSB), according to the RS485/RS422 standard, with a clock frequency of 100 kHz to 1 MHz.

Q: How does the SSI with Preset (S1) version differ from the standard SSI (SL) version?

It works the same as the (SL) version, but adds a preset function.

Q: What shaft and bearing options does the A/9115S offer?

The standard shaft is Ø11 h7; other diameters are available upon request. Sealed bearings (option W) are available in addition to the standard version.

El ELCIS 9115S (A/9115S) es un encoder absoluto SSI monovuelta de 16 bit con brida B10.

As a B10 flanged SSI absolute encoder, the A/9115S offers up to 16 bits of resolution per revolution, with Gray or Binary code output. The SSI serial interface (SL) is controlled by an external clock according to the RS485/RS422 standard at a frequency of 100 kHz to 1 MHz, and the SSI with Preset (S1) version adds preset functionality.
