RA-91
The actuator
with regulation, this time more powerful and compact
The RA-91 is a high-performance linear actuator capable of handling loads of up to 4,500N. It stands out for its power, as well as for its innovative stroke regulation system and advanced electronics that allow it to adapt to any application quickly and reliably.
Compact mounting dimensions
With a mounting hole length of only 118 mm + stroke, the RA-91's configuration makes it an ideal actuator for all types of applications with short installation dimensions.
Adjustable stroke to suit any application
The front or rear limit switch can be easily adjusted manually with a screwdriver to limit the stroke to a maximum of 22 mm to suit multiple applications.
High resolution position control
The electronic system allows precise control of the stroke position at all times thanks to the integration of a Hall sensor with a high-resolution analog signal from 0.3 to 3.3 VDC.
Elegant and discreet design
The black color and refined lines of the RA-91 actuator allows it to blend discreetly into any application without compromising the design. 
IPX4 protection degree
which guarantees protection against water spray from any angle. 
Innovative stroke regulation system
which allows the user to limit the actuator travel easily, reliably and quickly. 
Position control
The RA91 incorporates a hall encoder with high precision analog output. 
Advanced electronics
With a powerful microprocessor that ensures optimum operation of the actuator, position control and safety systems. 
Limit switches
which ensure that the actuator stops at the end of its travel. 
REGNER® products are subjected to rigorous life testing procedures to ensure that they perform reliably in applications and environments anywhere in the world.
We supply high quality electric linear actuators that have been tested, approved and certified by accredited certification entities for maximum safety and customer satisfaction.
