Linear Actuators PSF-EX / PSF-M-EX
Explosion-proof linear actuators with mechanical failsafe function or manual override
PSF-EX / PSF-M-EX
The approved explosion-proof linear actuator PSF-EX / PSF-M-EX with fail safe function has contactless, nonwearing travel detection with Hall sensor for exact positioning. Power spring is integrated for fail safe function in case of loss of power supply, either extending or retracting actuator stem.
