The Industrial Servo Cylinder, Series A2
The A2 Industrial Servo Cylinder is designed to excel in industrial/harsh environments where exposure to dirt, liquids, washdown, or other demanding conditions may be expected. The A2 Industrial Servo Cylinder makes use of the same robust control electronics and drive components as the A1, but includes several upgrades to increase its environmental ruggedness. Upgrades include:

Liquid-tight sealed enclosure
Enhanced shaft seal design
Rugged metal shell connectors
100% pressurized leak test to >15psi
Internal humidity control

The A-Series Servo Cylinder is a rod-style, brushless DC electromechanical actuator with built-in controller and Phase Index® absolute position sensor. Providing up to 530 lbf peak force and up to 7.75″ of travel, the Servo Cylinder was designed from the ground up to be extremely robust and very simple to use. After a simple USB configuration, power and signal are the only connections required to operate the Servo Cylinder.

Ultra Motion’s Phase Index® is seamlessly integrated into the Servo Cylinder. It provides absolute, digital position feedback of the actuator throughout the entire stroke and is also used for Field-Oriented Control of the brushless motor. Besides Phase Index®, no sensors are required to provide absolute position feedback of the actuator shaft and the BLDC rotor. The need for a linear potentiometer, LVDT, limit switches, 6-step hall sensors, incremental encoder, or resolver is eliminated. Simplifying the actuator system in this way greatly improves reliability, increases the operating temperature range, and reduces overall cost.

No homing required
No limit switches
No potentiometer wear
No sensor noise
No battery required to maintain absolute position
