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 ...

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 ...

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.

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 ...

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 ...

Incremental-rotation or linear encoders are very common, but normally they do not provide a direction signal. This design shows an easy way to detect forward or reverse direction. Incremental encoders ...

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 ...
