A/9115S Multi-turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The ELCIS 9115S (A/9115S) is a B10 flanged, multi-turn SSI absolute encoder with up to 30-bit resolution at 16,384 turns, outputting in Gray code or binary. For industrial use, it features a Ø11 h7 stainless steel shaft capable of withstanding 180 N of radial/axial load, 30 G of impact and 10 G of vibration, operating from -40 to +85 °C (-5 to +70 °C with wired output), up to 98% humidity without liquid state, and protection against reverse polarity and overvoltage spikes. It incorporates SMD technology.
As a B10 flanged SSI absolute encoder, the A/9115S offers up to 30-bit resolution at 16384 revolutions, with Gray or Binary 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.
It features a Ø11 h7 stainless steel shaft with a radial/axial load capacity of 180 N, shock resistance of 30 G (11 ms) and vibration resistance of 10 G (10–1000 Hz), operates between -40 and +85 °C (-5…+70 °C with cable output), with up to 98% humidity (non-liquid state), and has protection against reverse polarity and overvoltage spikes. It incorporates SMD technology.
- Resolution of up to 30 bit in 16384 turns.
- Serial interface SSI, with version SSI + Preset, according to RS485/RS422 a 100 kHz–1 MHz.
- Bearing life exceeding 105 h a 1000 rpm.
- Protection against reverse polarity and overvoltage spikes, with an unbreakable plastic disc.
Technical Frequently Asked Questions
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.
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.
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.
