ORLIN Christmas Logo

Working directly with SMAC’s dedicated encoder division in the USA, ORLIN Technologies is now able to offer optical encoders to customers’ specification with impressive lead times and low costs.


A manufacturer of PCB assembly equipment needed to replace a discontinued 17 MM diameter, flex mount, hollow shaft, 48,000 count Rotary encoder. They wanted a form, fit and function equivalent for a drop in replacement.

They also wanted high accuracy and low torque in the mechanical bearing system as they were using the motor encoder assembly in a positioning and force application. Not only was it necessary to come up with a way to design an optical encoder to meet the specifications for this application, but also to design a preloaded hollow shaft, ball bearing system for the 4 MM diameter bearings and 2 MM ID hollow shaft. Along with this, the means to test for accuracy and torque variation using the “Soft Land” feature of the SMAC controller was required. Accepted prototypes were made in 8 weeks.
