Cutting-Edge Actuator Position Sensor

phase index logo smallPhase Index is Ultra Motion’s innovative new position sensor technology for electromechanical actuators. The Phase Index position sensor is a digital, high-speed, high-resolution, non-contacting actuator position sensor that works over a wide temperature range and is resistant to vibration, shock, particulate debris, and condensing moisture. The sensor is self-calibrating, and does not need backup power to retain absolute position when power is off.
