Through-shaft sensor

Piher Sensors & Controls’ (Brighton, MI) hollow-shaft PST-360 contactless Hall-effect magnetic sensor was designed as a reliable solution for maintaining accurate pedal position (brake, accelerator or throttle) in x-by-wire applications, which is particularly important for on-road/car racing and off-road vehicles that demand accuracy even in the face of extremely harsh conditions. The sensor’s through-shaft technology is achieved by means of the mechanical design that allows it to wrap anywhere around the shaft, enabling sensing directly at the source. The company claims this allows engineers to integrate a fully featured rotary sensor directly on existing shafts without the packaging issues (such as gears) that typically accompany encoders or other through-shaft sensing devices.
