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 ...

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 ...

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.

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 ...

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 ...
