A/7115 Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The ELCIS 7115 (A/7115) is a programmable multi-turn absolute encoder with SSI serial output, capable of up to 65,536 steps (16 bits) per turn and 4,096 turns (12 bits). Mechanical robustness is a key requirement of this model: anodized aluminum housing and cover, Ø11 h7 stainless steel shaft with up to 8 kg radial/axial load, resistance to 50 G of impact and 12 G of vibration, and operation between -20 and +85 °C.
As a programmable multi-turn absolute encoder, the A/7115 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 cover and stainless steel shaft Ø11 h7 (up to 8 kg radial/axial load), 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/7115?
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 additional outputs does it support besides the SSI?
Sin/Cos at 1024 ppr (option S) or incremental RS422 of 1024, 2048, 4096, 8192 or 16384 pulses per revolution (options I1 to I5).
