The new Model A36R is EPC's most compact, high resolution, absolute thru-bore encoder yet.
Its innovative blue LED and reflective sensor technology deliver accurate high-resolution feedback in a compact thru-bore or hollow bore housing.
With numerous configurable features, the Model A36R is a perfect match for a wide variety of high-performance applications.
- Compact – 36 mm diameter and 1" depth
- High resolution – 22-bit single turn/24-bit multi-turn
- Easy mounting – Thru-bore or blind hollow bore
- Real-time feedback – BiSS C or SSI communication protocols
The Model A36R Absolute Encoder is designed for high performance in a compact mechanical package. Reflective technology guarantees accuracy and allows for absolute feedback in a thru-bore design.
The primary component of the EPC reflective technology architecture is an innovative system-on-chip optical device. It combines a blue LED emitter and sensor into one package and also offers a variety of on-chip programmable encoder functions. Reflective Encoder Technology »

Available with BiSS C or SSI communication protocols, it is especially suited to applications where an encoder needs to retain position information after power-off scenarios.
Learn more about BiSS communication protocol
The A36R is compatible with the BiSS C interface. BiSS C is similar to SSI and can be used unidirectionally like SSI, and stands for Bidirectional interface for Serial/Synchronous.
Unlike SSI, BiSS C also supports bidirectional communication and operates at speeds up to 10 Mbits/sec. BiSS-C can address internal registers in the encoder that can be read by and written to by the master with data about the encoder or motor and controller. BiSS-C encoders can also carry other digital data (temperature, etc.) and transmit the data to the master on demand, without interfering with real-time operation.
This communications protocol is used by industrial automation devices and a common high speed reliable digital solution between absolute encoders and motion controllers.
The Benefit of Absolute Positioning
Absolute encoders retain position information in the absence of power and eliminate the need for rehoming. An optional external battery or UPS-backed controller paired with the Model A36R’s low power turns-counting sensor ensures reliable data retention for the life of the encoder.
