IMA-S Integrated Motor Rod-Style Actuator - Stainless Steel
• 10 •
The IMA-S series actuators are hygienically designed linear actuators with integrated servo motors
designed for precise linear positioning. These actuators are designed for the food and beverage
processing industry and feature 316 stainless steel construction, IP69K ingress protection, blue seals/
O-rings, and hygienic fasteners/cord grips allowing for open machine designs and clean-in-place
compatibility. The product line also includes the IMA-SA model which incorporates an internal anti-
rotate feature eliminating the need for an external guidance mechanism making it a perfect actuator
for applications such as volumetric filling and pumping.
The IMA-S series integrates either a roller screw or ball screw technology with a servo motor and
variety of feedback options including absolute multi-turn, incremental, and resolvers to allow for easy
integration with most servo drives. The servo motor drives the ball or rollerscrew and converts rotary
motion into linear movement. The linear motion extends/retracts the thrust rod within the linear
actuator housing.
NOTE
IMA-S actuators are non-braking. When there is no current/torque input the thrust rod
can be moved freely. An internal integrated brake option is available if the motion system requires
the actuator to hold position in when no current/torque is input to the actuator
