Hengstler ACURO AC36 Absolute Rotary Encoders

Hengstler ACURO AC36 Absolute Rotary Encoders is an optical absolute rotary encoder with a multi-turn gearbox and optical scanning, size 36 mm. It is fitted with a solid shaft and physically compatible with standard incremental encoders. Thanks to its compact construction, the AC36 can directly replace corresponding incremental encoders. As a result,

it is possible to make full use of the technical benefits of absolute encoders in equipment manufacturing and medical engineering, to name but two of the many applications. The mechanical concept is based on a shaft assembly mounted in dual ball-bearings. The AC36 complements the ACURO industry product family while offering the same performance data as the 58 mm variants but with a smaller device size.

Unique within his class the AC 36 provides fully digital position data up to 22 Bit (single-turn) and 12 Bit (multi-turn) over the bidirectional synchronous interface with a variable clock rate up to 10 MHz. This corresponds a single-turn resolution of more than 130 000 measured steps. Backward compatibility is realized through the SSI interface together with 2048 sine-cosine periods per revolution.

The AC 36 is based on latest OptoAsic technology with an advanced diagnostic concept. A continuous plausibility check controls the internal signal processing for each increment. A code check guarantees that the encoder signal represents bit by bit the measured rotation. Also the operating temperature of the encoder can be measured, read out and monitored over warn and alarm bits with 8 bit resolution (1°C). Monitoring and controlling of the operating temperature ensures a maximum lifetime of the LED. Eventual failures are indicated early over warn bits.
