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 tted 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.
