The table below lists the key technical data relating to mechanical-pneumatic
position sensors. The figures listed in this table are typical examples and merely
provide an overview. Parameter Value Working pressure -95 – +800 kPa (-0.95 – 8.0 bar) Temperature range -10 – +60 °C Actuating force at 6 bar operating pressure 6 – 10 N Switching point pressure-dependent, varies max. 0.8 mm within
pressure range of 0 – 800 kPa (0 – 8 bar) Table 2.2.1: Technical characteristics of a mechanical-pneumatic position sensor 2.2.3 Notes on application
These limit switches are preferably for use in areas of application where pneumatic
components are already in u...
