Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

If you have a motor and you’d like to know where the shaft position is, you are likely to turn to an optical encoder scheme. However, as [lingib] points out, you can also use a magnet and a ...

For any designs that deal with large motors, isolation is a desired characteristic for both control and sense loops. Turn on, turn off, changes in load, changes in power, and unexpected events can ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

Baumer's newHS35 family ofincremental hollow shaft encoders includes a fully-programmable version, forheavy-duty positioning and speed control applications. Available in an IP67version, these rugged ...

CUI Devices has announced an incremental encoder for motors with shafts between 1 and 6.35mm in diameter. “The AMT12 series brings the same durability, accuracy and immunity to environmental ...

SICK has unveiled its next-generation family of large-bore hollow-shaft incremental encoders, the SICK DGS80. An innovative design concept has opened up versatile integration possibilities for the ...

We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...

Precisely tracking speed, acceleration, and position of a motor's rotor is an essential requirement for many motor control applications found in everyday equipment such as fax machines, elevators, and ...

Fabless chip maker CambridgeIC has improved the accuracy and speed of its non-contact position sensing technology. Implemented in the firm’s CAM502 chip, it uses resonant inductive sensors to deliver ...

Featuring a new shaft coupling that provides mechanical fault exclusion for connection to the user’s machine shaft, the encoders are of particular use in safety-related applications up to SIL 2 PL d ...
