This programmable Hall effect sensor combines key features not found in other 360° absolute position sensors, including a new switch function. This allows for substantial cost savings in a common package that are critical in safety and high reliability applications. Additionally, the PSC 360 also offers best in class temperataure performance (operating between -40° to +125° C) and impressive accuracy over 360° up to 0.5%. The device offers a programmable linear transfer characteristic capable of multiple positive and one negative slope.

The PSC 360 is offered in two packaging designs: the bushing / panel mount style or the adjustable TPS style with two slotted holes.  Both feature a very low profile packaging with heights of only 13mm.   

These sensors from Piher are truly non-contacting with a permanent magnet that is securely fastened to the shaft and act as the only moving component in the sensor. The technology itself is insensitive to variations in the magnets properties as well as axial and radial misalignment between the drive shaft and the control electronics. This means significantly improved reliability over temperature and time when compared to other available solutions.  Inside, the sensors electronics (sensing system) is precisely positioned near this magnet and is encapsulated in a molded plastic IP 65 rated package. These features are ideally suited to extreme environment exposure where shock, vibration and dust are unavoidable.  Further, Piher’s technology is not only true absolute, maintaining its position even after a power interruption, but it also offers full redundancy achieved with a dual core version within the same housing(s). The result is a highly configurable sensor that is completely sealed with a life expectancy of 50 million cycles that provides an ideal solution for the harsh environments found in industrial, agriculture and off-highway applications.
