Single-turn Absolute Encoder A/359

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

El ELCIS 359 (A/359) es un encoder absoluto monovuelta óptico de 2 a 11 bits, con acoplamiento interno en forma de estrella y sistema de puesta a cero entre encoder y máquina, ambos patentados, para aplicaciones industriales.

As an optical single-turn absolute encoder with LED source and phototransistors, the A/359 offers up to 2048 steps per revolution (11 bits) in Gray, Binary, Excess, BCD, or custom code. Output is parallel, with options for zero, latch, and parity LEDs; SSI serial (RS422) in Gray or Excess; or analog current or voltage (0–10 V) with 10-bit resolution.

Tiene carcasa Ø59 mm de aluminio anodizado y eje hueco H7 de acero inoxidable de Ø6, Ø8, Ø9,52 o Ø10 mm para 8 kg de carga radial/axial, resiste impactos de 50 G y vibraciones de 12 G, y trabaja entre 0 y +70 °C con protección IP64 en el lado del eje (IP66 en versión sellada).

Resolution of 2 to 11 bits: until 2048 steps per lap.
Five power ranges: 5 V and 15 V ±5 %, 8–24 V, 18–28 V and 10–30 V.
Analog output of 10 bits, in current or in 0–10 V in 360°.
Option of Parity for automatic checking of output stages.

Technical Frequently Asked Questions

What resolutions does the A/359 offer for each code?

In Gray, Binary and BCD, 8, 16, 32, 64, 128, 256 or 512 steps per revolution; in Gray and Binary, also 1024 or 2048; in Excess, Binary and BCD, 10, 100, 500, 1000, 180, 360, 720 or 900; and in Excess and Binary, 1440, 1800 or 2000. Other resolutions available upon request.

What limitations does analog output have?

Converts the 10-bit position (1024 div/revolution) into an analog current or voltage (0–10 V) for 360° of rotation. Available only with 15 V or 18–28 V power supply and 1024 resolution.

Can the SSI interface be used with binary or BCD code?

No. SSI serial output is only available with Gray or Excess code.
