DatasheetThe IPR20 pressure switch is designed for use in applications where media tend to deposit and clog the sensor. A compact front-flush process connection prevents hidden edges and drill holes, in combination with a resistant ceramic sensor optimal cleaning and maintenance can be ensured. The electrical connection is provided via an integrated clamping strip, while the IPG11 cable gland offers IP 67 dust and water protection. Its compact housing is made of high-quality stainless steel 1.4404 and is therefore suitable for almost all media. Our modular design concept provides a wide variety of products. Feel free to contact us if you need a customization that is not listed in this datasheet.
Applications:
- Gaseous media
- Liquid media
