Model A36R Absolute Encoder

The Model A36RTB (thru-bore) or A36RHB (blind hollow bore) offers a high-performance solution to your absolute feedback needs. Its innovative blue LED and reflective sensor technology deliver accurate high-resolution feedback in a compact thru-bore housing. The XXL multi-turn option adds a low-power turns-counting circuit offering a variety of backup options including EPC’s embedded battery cable, which has a long-life battery built directly into the controller-end of the cable.

This encoder is especially suited for applications where position information must be retained after system power loss. Its use of blue LED and reflective technology, along with excellent shock and vibration ratings, make it a highly versatile encoder.

Available with bore sizes up to 10 mm and a wide selection of flexible mounting options, the Model A36R is easily designed into a variety of applications.

BiSS C Encoder Interface

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 is a common high-speed reliable digital solution between absolute encoders and motion controllers.
