A MAG-G magnetic encoder with a split pulse wheel and scanning head. The new MAG(-G) 50-1200 magnetic encoders from Johannes Huebner GmbH can be installed without bearings or housings, and the system ...
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 ...
Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...
An absolute encoder includes a coding disk in binary or gray code format, the electronics to read it, and communications circuits. A multiturn encoder may have several disks connected by gears as ...
Similar in size and shape to the common panel-mounted potentiometer, the incremental rotary encoder provides an inexpensive ‘digital’ alternative to the analog potentiometer. It is typically used to ...
This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.
Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
