CUI Devices’ Motion Group has introduced a new series to its AMT incremental encoder family. Based on the existing AMT11 series package, the new AMT11A series is not subject to silicon related lead-time constraints and can serve as a drop-in replacement for AMT11 encoder models. AMT11A encoders offer 16 quadrature resolutions from 96 to 4,096 […]

How do Hall effect sensors work and where are they used in motion applications?
The Hall effect is an outcome of the Lorentz force at work. When a thin conductor (or semiconductor) has a steady flow of current running through it and a magnet is placed so that its magnetic field runs perpendicular to this current, the magnetic field of the current reacts to the magnetic field of the […]
Feedback on stepper motors for better positioning and holding (and less ringing)
Feedback-equipped stepper motors are not a complete substitute for servomotors, but they can provide a reliable alternative for many real-world applications. These motion-design solutions improve machine performance without breaking the bank. By Jim Stevens • Product Specialist | POSITAL Inc. Stepper motors are a top choice for many motion and position control applications. They’re available […]
What is a gated index pulse for incremental encoders?
Incremental encoders typically use two square-wave signals in quadrature (out of phase by 90 degrees) to track position and direction of motion. But because they only track incremental position (not absolute position) they’re not able to determine the true position of the motor and connected equipment after a shut-down or power loss. So most incremental […]
Quantum Devices encoder + module now simplify BLDC motor commutation setup
Quantum Devices Inc. now sells time-saving programming technology that simplifies BLDC communication programming. It’s aimed at reducing production assembly and configuration time for OEMs that need incremental encoders to precisely control the motion and position on axes in equipment they produce. The new offering consists of: A QM35 EZ-Comm low-profile incremental encoder with a full […]
What is a sine encoder (aka sine-cosine encoder)?
A sine encoder is similar to an incremental encoder in design and function. Both devices measure either rotary or linear position changes and direction, and both are available with either optical or magnetic sensing technology. The primary difference between the two is that sine encoders supply position and direction information as 1 Volt peak-to-peak (1 […]
Capacitive incremental encoders support shaft sizes to 5/8 in.
CUI’s Motion Group has added a new series to its AMT incremental encoder family designed to support larger motor shaft sizes from 9 mm to 15.875 mm (5/8 in.). The AMT13 series, based on CUI’s proprietary capacitive ASIC technology, brings the same high levels of durability, accuracy, and immunity to environmental particulates as current AMT […]
