Single-turn Absolute Encoder A/363S

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

The ELCIS 363S (A/363S) is a 2-13 bit optical single-turn absolute encoder in a metal housing with servo-type mounting flange, for industrial use.

As an optical single-turn absolute encoder with a ≥ 100,000-cycle LED source and phototransistors, the A/363S offers up to 8192 steps per revolution (13 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.

Anodized aluminum base and cover and stainless steel shaft Ø9.52 h7 for 5 kg radial/axial load; withstands 50 G impacts and 12 G vibrations, works between 0 and +70 °C and has IP65 protection on the shaft side (IP66 sealed, IP53 under torque), with a bearing life of 1.5 × 10⁹ revolutions.

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, 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/363S 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.
