A/758H Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The ELCIS 758H (A/758H) is a programmable, multi-turn absolute encoder with a Ø58 mm housing, up to 65,536 steps (16 bits) per revolution and 4,096 revolutions (12 bits). Its robust mechanical design and ease of assembly allow for a wide range of applications: anodized aluminum base, VALOX 420 cover, and Ø10 h7 stainless steel shaft with up to 2 kg of 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 in a 58 mm housing with a 10 mm shaft diameter, the A/758H 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 an anodized aluminum base, VALOX 420 cover and stainless steel shaft Ø10 h7 (up to 2 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).
- Casing Ø58 mm with axis Ø10 mm.
- 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 (option PR) via software through USB or through the interface itself RS422.
- Impact resistance of 50 G (11 ms) already vibrations of 12 G (10–2000 Hz).
Technical Frequently Asked Questions
What connections does the A/758H support?
1 m cable (CV, IP65), 10-pin MS310A18-1P (CL, IP65) or MS310R18-1P (SL, IP66) connector and 12-pin Eml 121 (CH, IP66) connector, with radial (R) or axial (–) output.
What is the maximum resolution it offers?
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), via PC software connected by cable to a USB port that powers the encoder, or via the RS422 interface itself, in ASCII code. The software and cable are supplied upon request.
