Manufacturer: ELCIS Encoder
Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS

The ELCIS 759C (A/759C) is a programmable, multi-turn, hollow-shaft absolute encoder with up to 65,536 steps (16 bits) per revolution and 4,096 turns (12 bits), designed for direct mounting on motor shafts. It features an anodized aluminum base and a VALOX 420 cover, with a stainless steel H7 hollow shaft available in diameters of 6, 8, 10, 12, or 15 mm, an anti-rotation bolt, and a radial/axial load capacity of up to 4 kg. It withstands shocks of 50 G and vibrations of 12 G, and operates in temperatures ranging from -20 to +85 °C with IP64 protection on the shaft side (IP66 in the sealed version).

As a programmable multi-turn absolute encoder with an OptoASIC sensor, the A/759C offers up to 65,536 (16-bit) resolution per revolution and up to 4,096 revolutions (12-bit), with SSI serial output (S1 interface with preset) in Gray or Binary code. It also supports an additional Sine/Cos output at 1024 ppr or incremental RS422 output of up to 16,384 pulses per revolution, and, with the PR option (max. 8,192 div/revolution), allows programming of code, resolution, preset, and address via software through USB or the RS422 interface itself.

With anodized aluminum base and VALOX 420 cover, and hollow H7 stainless steel shaft of Ø6, Ø8, Ø10, Ø12 or Ø15 mm (up to 4 kg radial/axial load) with anti-rotation bolt, it withstands impacts of 50 G and vibrations of 12 G, and works between -20 and +85 °C with IP64 protection on the shaft side (IP66 in sealed version).

Programmable resolution up to 65536 steps per revolution (16 bit) in 4096 turns (12 bit).
Serial interface SSI with preset, in code Gray either Binary programmable (PR option) by software via USB or through the interface RS422.
Additional exit Sin/Cos a 1024 incremental ppr RS422 up to 16384 pulses per revolution.
Impact resistance of 50 G (11 ms) already vibrations of 12 G (10–2000 Hz).

Technical Frequently Asked Questions

What is the maximum resolution offered by the A/759C?

Up to 65536 (16 bit) resolution per revolution in 4096 revolutions (12 bit), selectable between 1024, 4096, 8192, 16384, 32768 or 65536 divisions per revolution.

How do you program the encoder?

With the PR option (max. 8192 div/revolution), programming is possible via PC software connected by cable to a USB port that powers the encoder, or through the RS422 interface, which allows programming and data exchange in ASCII code. The software and cable are supplied upon request.

What hollow shaft diameters does the A/759C support?

Hollow stainless steel H7 shaft of Ø6, Ø8, Ø10, Ø12 or Ø15 mm (other diameters on request), with anti-rotation bolt for direct application to the shaft of a motor.
