POSITAL updates cube encoders with programmable measurement

Posital Cube Encoder

POSITAL has updated its cube encoders – incremental rotary encoders with a cube-shaped housing – around its magnetic measurement platform.

Cube encoders have been popular with machine builders since the 1960s, largely because they are easy to install without special mounts or brackets.

The programmable measurement module inside the cube provides high levels of accuracy and dynamic response in a rugged package that is tolerant of shock and vibration loading, dust and moisture.

Resolution (number of pulses per revolution) can be set anywhere from one to 16,384 pulses per revolution (PPR) by simply updating the devices’ software, with no changes to mechanical components. Similarly, pulse direction and the output driver – either Push-Pull (HTL), RS422 (TTL) or Open Collector (NPN) – are defined through software.


Device programmability is especially significant for distributors, system integrators or machine builders since it helps them control inventories. With programmable devices, they can hold a relatively small stock of ‘standard’ models and set them up for specific applications on an as-needed basis.

POSITAL’s cube encoders are designed to be used as drop-in replacements for traditional cube designs, with identical mechanical dimensions and interfaces.
