TECHNICAL DATASHEET Absolute Encoder AC 36 - BiSS / SSI  Overall length: 36 mm  For equipment engineering and industry  Up to 22 Bit Resolution Singleturn + 12 Bit Multiturn  Solid or hollow shaft version available  +100°C operating temperature  10,000 rpm (continuous)  Optical encoder with a true geared multiturn  Interfaces: SSI, BiSS-B or BiSS-C  Option Sinewave 1 Vpp  Bandwidth 500 kHz The AC 36 is an absolute optical encoder with a true geared multiturn, optical sensing technology and 36 mm diameter. Equiped with a solid-shaft the AC 36 is mechanical compatible with all common incremental encoders. The compact design allows to replace the adequate incremental encoders directly. As a result the technical facilities of absolute encoders can be used for the first time in equipment engineering and also in medical engineering. The mechanical design consists of two ball bearings supported mechanical shaft assembly. The AC 36 comple® ments the ACURO -industry series with small frame sizes and the same performance as 58 mm versions. BiSS-Interface Unique within his class the AC 36 provides fully digital position data up to 22 Bit (singleturn) and 12 Bit (multi-turn) over the bidirectional synchronous interface with a variable clock rate up to 10 MHz. This corresponds a singleturn resolution of more than 130 000 measured steps. Backward compatibility is realized through the SSI interface together with 2048 sinecosine periods per revolution. Integrated diagnostic system 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 mesured 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.
