Process optimization in heavy industrial applications often requires changing the read resolution without disassembling mechanical components. The ELCIS 790 Multiturn Absolute Encoder solves this problem with its field-programmable 100% configuration, allowing integrators to adjust the resolution, direction, and preset value via software or an RS422 terminal without interrupting the line.

This robust device integrates advanced OptoASIC technology to deliver absolute resolutions of up to 65,536 divisions by 4,096 rotations via an SSI bus (500 kHz). Additionally, it features incremental Sine/Cosine (1024 ppr) or RS422 output channels, making it the perfect hybrid for simultaneous speed and position control loops.

Both the base and the cover are made entirely of anodized aluminum, providing superior interference isolation. Its solid stainless steel shaft (Ø 10 mm h7) supports loads of 5 kg, resisting strong vibrations (12 G) and mechanical shocks of 40 G in environments from -20 to +85 °C. Available in guemisa.es.

  • Complete parameterization via software (resolution, Gray/Binary code, address and preset).
  • Dual architecture that provides absolute SSI position and incremental Sin/Cos velocity simultaneously.
  • Extreme industrial durability with anodized aluminum body and IP66 watertight sealing options.
  • High rotation speed, supporting up to 6000 RPM continuously (in standard IP65 version).

Technical Frequently Asked Questions

How do you program the encoder once it's installed on the machine?

Parameterization can be performed using PC software with a special USB cable that powers the device, or via the RS422 interface, which allows data exchange and reconfiguration of the encoder using standard ASCII commands.

Can it be used in applications where there are direct water splashes?

The standard model provides IP65 protection, sufficient for dust and splashes. For environments with high-pressure water jets or high humidity, the sealed bearing option (Option Z) is available, which raises the protection to IP66, limiting the maximum continuous speed to 3000 RPM.

What physical signals does your connector deliver?

Through its industrial connectors (e.g., MS310A18 or M23), the equipment delivers the SSI signal (Clock, Data), the complementary incremental signals (Sin/Cos or RS422), and the dedicated pins for power (10÷30V DC), the Preset signal and Address (DIR).
