901 Factory set pressure switch

Introducing our advanced Factory-Set Pressure Switch! This cutting-edge device effectively monitors overpressure, vacuum, or differential pressure of both liquid and gaseous media, including aggressive substances. Boasting hassle-free operation, the pressure setting and switching differential come pre-configured by our expert manufacturer, ensuring accurate and reliable performance. For extreme temperature conditions exceeding 85°C, a durable metal or PPS pressure connection is recommended. Customisation options are available upon request, allowing you to choose different sizes, plastics, or brass nickel-plated connections. This versatile pressure switch finds wide-ranging applications and is accompanied by comprehensive technical data, a product configurator, and optional accessories to meet your specific needs.

Product Highlights

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.
