Single-turn Absolute Encoder A/3102

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

El ELCIS 3102 (A/3102) es un encoder absoluto monovuelta óptico de 2 a 13 bits, en carcasa metálica estanca al polvo y a la humedad, con fijación frontal o lateral.

It is optical, with an LED source and phototransistors, and delivers the position in Gray, Binary, Excess, BCD, or custom code, up to 8192 steps per revolution (13 bits). The output is parallel, with options for zero, latch, and parity LEDs; SSI serial (RS422) in Gray or Excess; or analog in current or voltage (0–10 V) with 10-bit resolution.

Tiene carcasa Ø102 mm y eje de acero inoxidable Ø12 h7 para 12 kg de carga radial/axial, resiste impactos de 50 G y vibraciones de 12 G, y trabaja entre 0 y +70 °C con protección IP65 en el lado del eje (IP66 en versión sellada).

Resolution of 2 to 13 bits: until 8192 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 (1024 div./revolution), 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/3102 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, 2048, 4096 or 8192; in Excess, Binary and BCD, 10, 100, 500, 1000, 180, 360, 720 or 900; and in Excess and Binary, 1440, 1800, 2000, 2880, 3600 or 4000. 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. The SSI serial output is only available with Gray or Excess code. For Binary or BCD, the parallel interface is used, where the Latch input is standard.
