Absolutely Incremental – Innovations in Magnetic Linear Encoder Technology

Linear encoders – absolute or incremental?  Incremental encoders are simple, inexpensive, and easy to implement, but they require that the machine be homed or moved to a reference position.  Absolute encoders don’t require homing, but they’re usually more expensive, and … Continue reading

Aw, yiss…BiSS!

There’s a cool new serial data interface coming on the scene. It’s called BiSS (Bi-Directional Synchronous Serial), and is an open-source, free-to-license digital interface for sensors and actuators. BiSS is hardware compatible to the industrial standard SSI (Serial Synchronous Interface) but offers … Continue reading

What is “Minimum Edge Separation” and Why Should I Care?

When it comes to magnetic incremental linear encoders, sometimes the configurable performance parameters can be a tad obscure.  One of the most puzzling is the feature called “Minimum Edge Separation”. Just for review, a magnetic incremental linear encoder system consists of a … Continue reading
