Product Highlights

The DS400P Pressure Switch offers a wide range of features and capabilities. With a nominal pressure range from 0 … 100 mbar up to 0 … 40 bar, it is suitable for various applications. The switch comes with either one or two independent PNP contacts, which can be freely configured based on the requirements. Additionally, it provides an analogue output with options for 2-wire (4 … 20 mA) or 3-wire (4 … 20 mA), and other output types can be requested. One of its special characteristics is the 4-digit LED display, which allows for clear indication of measured values. The display module is rotatable and configurable, providing flexibility for different installation orientations. The switch also offers configurable contacts, allowing users to set switch on/off points, hysteresis/window mode, and switch on/off delay. For applications requiring a hygienic design, a hygienic version is available. Furthermore, optional versions include the IS-version Ex ia, which is intrinsically safe for gases and dusts, as well as customer-specific versions to cater to individual needs.
