Company Stories

Customer Spotlight: Hydrow uses motion control to redefine rowing experience

The Hydrow® Live Outdoor Reality™ rower features a patented drag mechanism that is electromagnetic and computer-controlled that was designed to make the machine feel as close as possible to actually being on the water. Precise position feedback was an important part of the design and a US Digital optical encoder is a part of that system.

Our Focus is Making Our Customers Successful

We think the best way to help our customers is to empower our customer service team to listen to their needs and act accordingly. They aren't locked into scripted responses and predetermined outcomes. Learn more about our team and our commitment to helping our cusomters.

How we use automation to create jobs

US Digital CEO David Madore and COO Neal Donowitz share how the company uses automation to create jobs, not eliminate them.

Our $80 solution saved a customer thousands

When a motor manufacturer needed help validating encoder output for one if its customers, the manufacturer turned to us for help. They walked away with a completely customized software solution and only paid $80.

Why we design and manufacture in-house

US Digital Founder and CEO David Madore shares why we believe in investing in vertical integration and doing as much as possible in house.

Guess What We Did With a Trash Bag

Our team of practical problem solvers take on an unexpected (but minor) issue in our plant using trash bags, tape and some ingenuity.

Our New and Improved Injection Molding Machine

Mechanical Engineer Camilla Garcia recently completed work on a new automated machine that processes encoder module lenses after they are injection molded. The new machine improves upon existing design and effectively gives us 3 extra days of runtime on the machines each week.

Meet LIAS, our new custom machine vision system

We recently built and installed a custom machine vision system to automate a visual inspection process in our plastic injection molding area. The system, called LIAS or the Lead frame Inspection Automation System, checks our optical encoder module lead frames for defects from the manufacturing process and stores them in cartridges that are sent to our clean room for the next part of the manufacturing process.

Automating SMT line using custom panel loader

After releasing our E4T and E8T miniature optical encoders, we decided to take a look at improving efficiency in our surface mount technology (SMT) line by automating the PCB loading process. Learn more about our custom solution, and how we used our E6 optical encoders and MD3 microstepping motor drivers in the build.

Streamlining an assembly process with a delta robot

When laser cutting room operators ran into issues preparing new, miniature optical encoder disks for a new product, US Digital turned to its in-house engineering team and a delta robot to solve the problem. The automation now allows operators to spend their time on other tasks and increases efficiency of production of the E4T encoders.
