What is Phase Index?

Phase 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. The absolute position of an actuator is available immediately upon power-up and with full accuracy. No power-up homing routine is needed to establish an accurate absolute position.

Our series B1 actuators are 50% smaller than our standard B2 series parallel mount linear actuators, and can be configured to forces up to 500 lbf and speeds to 20 in/s. Due to the B1’s extremely high power density these actuators are being used in demanding applications where size and weight are critical factors such as control surfaces, unmanned vehicles, and robotics. The B1 series is available with both high performance brushed and brushless dc motors.

Ultra Motion B1 Actuators are popular in aerospace applications and have met DO-160 requirements.

Ultra Motion has used its long history in underwater linear motion control to develop a high performance, ruggedized, subsea linear actuator. Currently available as custom units only, these submersible actuators provide long life in demanding underwater applications up to depths of 20,000 feet (10,000 psi). Features include:

• Type III hard coat anodized aluminum case
• Stainless 316 Shaft
• Sacrificial anodes for maximum corrosion protection
• Pressure balanced, oil-filled (PBOF) connectors
• Enhanced thermal dissipation due to internal motion of oil, allowing for very high power density actuators
