Valid for all pressure switch with microswitches of the DCM,VCM,DNM, DNS, DDC series. The technical data of

the component tested units deviate in part slightly. (Please refer to type sheet) All pressure switches can

operate under vacuum, the device is not damaged by this. < 1 % of the working range (for pressure ranges > 1

bar) Up to 4 g no noteworthy deviations. With sinusoidal pressure application and room temperature, 10 x 106

switching cycles. The expected life time depends strongly upon the type of pressure application, therefore

this figure can serve only as rough estimate. With pulsating pressure or pressure impacts in hydraulic

systems, pressure surge reduction is recommended. Overvoltage category III, contamination class 3, reference

surge voltage 4000 V. The conformity to DIN VDE 0110 (01.89) will be confirmed. The parts of all pressure

switches in contact with the medium are oil and grease-free (with the exception of series HCD… und DPS…).

The sensors are hermetically encapsulated, they contain no seals (see also additional function ZF 1979,

special packing).Higher medium temperatures are possible if the above limit values at the switching

mechanism are ensured by suitable measures (e.g.siphon),Vacuum Repetition accuracy of the switching points
