RS400 Rollover Sensor


The RS400 is the fourth generation of Liquip Rollover Sensor and symbolises Liquip’s constant drive for safety and continuous improvement.

Rollovers can occur in the blink of an eye and in the event of a rollover, the RS400 is a safe and effective way to ensure electrical sources of product ignition are isolated.

The RS400 complies with Australian standards by signalling to the the isolation switch to disconnect power to the truck system in the event of a rollover.

The RS400 enables vehicles to meet the legal requirement of roll-over sensing (AS2809:2020). The RS series have been tried and proven to operate in Australia's harsh operating conditions and are backed by Liquip's Australia wide service network.

The Roll Over Sensor has been designed for high reliability undergoing thorough environmental and lifetime testing.

The RS400 roll over sensor is compatible with most common battery master isolation switches and will provide enhanced safety when used with battery isolation switch available via Liquip.
