The Model A36R Absolute Encoder is designed for high performance in a compact mechanical package. The 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 for a variety of applications. 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. 

The Model A36R absolute thru-bore encoder offers:

• Up to 22-bit single turn / 24-bit multi-turn resolution
• Thru-bore or blind hollow-bore styles
• BISS C and SSI communications
• 36 mm diameter housing, 25.4 mm (1.000″ depth)
• Operating temperature range of -40° C to 120° C
• Optional battery/backup power interface for data retention in the absence of primary power

Reflective Technology

The central component of the BEPC reflective technology architecture is an innovative system-on-chip optical device. This device integrates a blue LED emitter and a sensor into a single package, accompanied by a range of on-chip programmable encoder functions. This cutting-edge reflective technology offers significant benefits over the traditional optical transmissive approach typically employed in encoders:

Compact Design: Our reflective technology enables an exceptionally compact design. Unlike transmissive technology, which necessitates two separate PCB assemblies, this technology requires only a single PCB assembly. This reduction in hardware complexity and space requirements is a notable advantage.

Signal Clarity and Precision: The inclusion of a blue LED with a short wavelength in the integrated package enhances signal contrast and minimizes jitter. Furthermore, the close proximity of the emitter and sensor within the same assembly significantly reduces optical crosstalk. As a result, this technology offers superior resolution, accuracy, and overall performance compared to traditional encoders.

Versatile Position Detection: Unlike many magnetic encoders that rely on magnets positioned at the end of the encoder shaft to detect position, reflective technology enables off-axis position detection. This versatility allows for a wider range of mounting options, including those suitable for thru-bore style shafts.
