The Pressure Switch 901 is a versatile device designed for various applications. It offers different setting ranges to suit specific needs. The standard/extended types 901.1x have factory-set switching points between 5 mbar and 200 mbar, or 200 mbar and 1,000 mbar, with a maximum positive working pressure of 0.5 / 4 bar or 1 / 4 bar, respectively. The 901.41 type provides switching points between 500 mbar and 3,000 mbar, with a maximum positive working pressure of 10 bar. For higher pressures, the 901.51 type has factory-set points between 1.0 bar and 12 bar, with a maximum positive working pressure of 25 bar. The 901.2x type caters to negative pressure settings, ranging from -5 mbar to -200 mbar, or -200 mbar to -900 mbar, with maximum working pressures of 0.5 / 4 bar or 1 / 4 bar, respectively. It operates in ambient temperatures from -20°C to 85°C and media temperatures up to 85°C or 130°C depending on the material of the pressure connection and diaphragm. The electrical rating includes AgNi and gilded contacts, and the electrical connection is made using an AMP flat plug 6.3 x 0.8 mm according to DIN 46244. Depending on the used protection cap, the switch offers protection classes of IP44, IP54, or IP65.
