Single-turn Absolute Encoder A/790
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
El ELCIS 790 (A/790) es un encoder absoluto monovuelta programable de hasta 65536 pasos (16 bit), con interfaz SSI y salidas incrementales Sin/Cos a 1024 ppr o RS422 hasta 16384 pulsos por vuelta.
Con sensor óptico OptoAsic, el A/790 entrega la posición por la interfaz serie SSI con Preset en código Gray o Binario. Con la opción PR (máx. 8192 div/vuelta) se programan código, resolución, preset y dirección por software vía USB o por la interfaz RS422; software y cable se suministran bajo pedido.
Base y tapa de aluminio anodizado y eje de acero inoxidable Ø10 h7, con hasta 5 kg de carga radial/axial. Resiste impactos de 40 G y vibraciones de 12 G, y trabaja entre -20 y +85 °C con protección IP65 en el lado del eje (IP66 en versión sellada).
- Resolutions of 1024, 4096, 8192, 16384, 32768 either 65536 div/vuelta.
- Exit SSI with preset, in code Gray either Binary, with a maximum clock frequency of 500 kHz.
- Additional exit Sin/Cos a 1024 incremental ppr RS422 up to 16384 ppr.
- Impact resistance of 40 G (11 ms) already vibrations of 12 G (10–2000 Hz).
Technical Frequently Asked Questions
What interface does the A/790 use to transmit position?
A synchronous serial SSI interface with clock, address (DIR) and preset inputs, with RS422 output electronics. The value is transmitted starting from the most significant bit (MSB).
Can the encoder resolution be programmed?
Yes, with the Programmable (PR) option (max. 8192 div/revolution), the output code (Gray or Binary), resolution (up to the encoder's maximum physical resolution), preset value, and counting direction can be set using PC software connected via USB, or via an RS422 interface in ASCII code. The software and cable are available upon request.
What additional outputs does it support besides the SSI interface?
The A/790 supports Sin/Cos output of 1024 ppr (option S) or incremental RS422 output of up to 16384 pulses per revolution (options I1 to I5: 1024, 2048, 4096, 8192 or 16384).
