THE ROLL-OVER SENSOR
The REDARC Rollover Sensor (ROS) represents a significant improvement over the existing
rollover sensors in the market. It enables trucks to meet the roll-over sensing requirements of
AS2809:2008, signalling the isolation switch to disconnect power to the truck system in the event
of a truck rollover. It has been designed for high reliability, undergoing thorough environmental
and lifetime testing.
The REDARC ROS has been designed for easy periodic testing with a simple pin-removal and tilt
mechanism featuring retained pins to prevent them being lost.
