Position Transducers with Restoring Spring
Model: KPY
Category: Machine Tools / Others / Other Machinery
Characteristics
KPY series position sensors employing conductive-plastic resistance and collector tracks provide direct means of measuring position or profile, without the need of a solid mechanical coupling. The side connection creates a through-rod structure with double rod support, guaranteeing greater overall strength of the transducer.
One important feature of the KPY Series is the industry proven double-bearing systems on both actuator shaft and spring. This arrangement reduces side load errors that could occur in an application such as cam-following and is one of the design factors that enable the outstanding linearity of this series. The return spring automatically returns the rod to zero position, making the transducer suitable for comparator applications.
KPY2 with stainless steel ball and KPY3 with roller bearing both are suitable for applications where the object to be measured is not subject to shifts transverse to the transducer axle.
