The ACW4 and TCW4 Series are two-part rotary hall effect sensor assemblies and magnet aimed for absolute single-turn or absolute multi-turn measurement respectively, offering design flexibility and protection from the environment.
The single-turn (ACW4) modular encoder is ideal for applications measuring less than one turn (360° of rotation), for example, in a parking barrier that swings 90 degrees and returns to the original position. The multi-turn (TCW4) is used in applications that require to measure both the degrees and the number of rotations, as measuring the opening of a rollup freight door. Both versions use noncontacting technology which ensures repeatability reducing the need for maintenance and increasing the overall lifetime of the application.
ACW4 and TCW4 hall effect sensors feature a modular design and a wide range of interface options which make them easy to integrate to most applications.
