Target pucks use inductive sensors and integral sensors to detect the open or closed position of a valve.Target pucks are used to provide reference points for the accurate alignment of equipment and machinery. This alignment ensures precise positioning.

A round target (also known as a 'puck') is used for reliable position feedback of pneumatic quarter-turn actuators or valve plates.

The puck is mounted directly on the actuator shaft. It is equipped with two metal screws that are mounted at different heights and offset by 90°. A dual inductive sensor with two integral sensors detects the upper or the lower metal screw and, thus, the "open" or "closed" position of the valve.

The system operates without contact or wear and is self-cleaning. It is virtually resistant to external influence and insensitive to mechanical stress such as vibration and shock.
