The sensor does not require an additional power supply, i. e.
SIPART PS2 (not for Ex d version) can be operated in a 2-wire
system. The NCS (Non Contacting Sensor) consists of a potted
sensor housing which must be mounted permanently and a
magnet which is mounted on the spindle of linear actuators or on
the shaft butt of part-turn actuators. For the version for travels
>14 mm (0.55 inch), the magnet and the NCS are premounted
on a stainless steel frame and offer the same interface mechanically
as the positioner itself, i. e. they can be mounted using the
standard mounting kits 6DR4004-8V, -8VK and -8VL.
