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
When it comes to selecting the most appropriate position detection technology for an absolute rotary encoder application, it’s helpful to consider the general advantages and potential disadvantages of the two most common approaches: optical and magnetic. Optical Encoders Internally, absolute … Continue reading
Precision Tape Magnetization Leads to Precision Position Measurement The key to ultimate accuracy for any magnetic linear encoder system is the precision of the magnetic encoding on the tape (sometimes called a scale). Sensors inside the encoder read head respond … Continue reading
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
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
