AC36 36mm Absolute Optical Rotary Encoder

Product Overview

The AC36 is a high-performance optical absolute rotary encoder equipped with a precise multi-turn gearbox and advanced optical scanning technology. Engineered with a compact 36 mm footprint and a solid shaft, this device is physically compatible with standard incremental encoders, serving as a seamless, direct replacement.

By upgrading to the AC36, designers can unlock the superior reliability and precision of absolute encoding for demanding applications, including automated equipment manufacturing and medical engineering.

Key Features & Mechanical Design

  • Compact Powerhouse: As a proud member of the ACURO industry product family, the AC36 delivers the exact same robust performance data as larger 58 mm variants, but within a highly space-saving 36 mm profile.
  • Durable Construction: Built for longevity and stable operation, the mechanical design is anchored by a solid shaft assembly securely mounted within dual ball-bearings.
  • Effortless Upgrades: Its physical compatibility allows you to directly replace outdated incremental encoders without needing to heavily modify your existing mechanical setup.
Hengstler AC 36 Absolute Encoder (BiSS / SSI) Technical Specifications
● GENERAL
DescriptionThe AC 36 is an absolute optical encoder with a true geared multiturn, optical sensing technology and 36 mm diameter. Equipped with a solid shaft, the AC 36 is mechanically compatible with all common incremental encoders, allowing the compact design to directly replace adequate incremental encoders. This brings absolute-encoder technical capability to equipment engineering and medical engineering applications for the first time. The mechanical design uses a two-ball-bearing supported mechanical shaft assembly. The AC 36 complements the ACURO®-industry series with small frame sizes and the same performance as 58 mm versions.
Key FeaturesOverall length 36 mm; for equipment engineering and industry; up to 17 Bit resolution singleturn + 12 Bit multiturn; solid shaft 6 mm (hollow shaft version: AD 36); +100°C operating temperature; 10,000 rpm (continuous); optical encoder with true geared multiturn; BiSS or SSI interface; option sinewave 1 Vpp; bandwidth 500 kHz.
BiSS InterfaceUnique within its class, the AC 36 provides fully digital position data up to 17 Bit (singleturn) and 12 Bit (multiturn) over the bidirectional synchronous interface with a variable clock rate up to 10 MHz — corresponding to a singleturn resolution of more than 130,000 measured steps. Backward compatibility is realized through the SSI interface together with 2048 sine-cosine periods per revolution.
Integrated Diagnostic SystemBased on latest OptoAsic technology with an advanced diagnostic concept. A continuous plausibility check controls internal signal processing for each increment. A code check guarantees that the encoder signal represents the measured rotation bit by bit. Operating temperature can be measured, read out and monitored over warn and alarm bits with 8-bit resolution (1°C), ensuring maximum LED lifetime; eventual failures are indicated early via warn bits.
