Profile: Paw Taw John Services, Inc. deals with motion control product services and systems. We also offer servo motion controllers, custom motion control systems, linear motion sensors, lasers and encoders. Our S-series Servosensor™ is a complete servo controller installed and interfaced inside an MTS® R-series platform. It consists of a servo controller module (SCM), driver module (DM) and sensing element (SE) combined inside the sensor head body. The MTS® proprietary technology is integrated directly to the SCM. This integration in the SCM provides the servo sensor controller with very fast displacement measurements and servo control outputs. Our absolute encoders generate a unique binary word output for each resolvable shaft position so that each shaft position is fully determined. By using absolute position rather than incremental count data, the shaft position is always known, even after power interruptions or in the presence of electrical noise. System design can also be simplified because there is no need to perform a reference cycle or return to home function to determine the true machine position.
