Valve position sensor

To combat problems associated with using a box containing microswitches, ifm electronic came up with the idea of two inductive sensors in one body that just sits on the actuator. Remote feedback of valve position is further simplified with the IN5409, a new version of the IND valve sensor from the company. The new unit is said to be even more robust than its predecessors and is designed for easy connection.

The terminal chamber at the back is reached by loosening two captive screws at the rear of the unit, next to the twin glanded entries. The cable glands themselves are dimensioned to allow the attachment of steel armoured cable, as often required with such installations.
