Optional Rolaram®Actuator Limit Switch
Other limit switches can be supplied to suit most applications e.g:
•
Different sizes, shape, design and enclosure electro-mechanical limit switches
• Inductive proximity sensor
• Hazardous Area rated electro-mechanical limit switch
• High or low temperature rated limit switches or sensors. For all of these options consult Power Jacks for details
Encoders for Rolaram® Actuators
Encoders for Rolaram linear actuators can be provided fitted to the rear of the electric motor (beneath the cowling). For further details
please consult Power Jacks.
Optional Materials for Rolaram® Actuator Construction
As with all other Power Jacks products these actuators can be manufactured with alternative materials to meet the most demanding
application. Consult Power Jacks for advice.
