The VRC Limit Switches and Transmitters have no agency approval for use in hazardous areas. The positioner enclosure is a composite material and offers no explosion proof protection.

To meet the requirement for switches or transmitter the VX positioner can be ordered with an Accessory mounting cover that allows for a metal housed hazardous location switch or transmitter to be mounted to the top of the positioner.

The S2 switch is a hermetically sealed switch maybe allowed for use in some hazardous areas. Consult the National Electric Code or your local approval authority.
