Omni Weatherproof Pressure Switch
Brand: SOR IncDesigned to provide protection from the elements, the SOR Omni weatherproof pressure switches are available in two switch configurations–diaphragm for most applications, and pivot seal type for hydraulic applications (where high shock pressures and cycle rates are expected).
These small, compact, low-cost switches are often used in OEM applications.
- Environmentally sealed snap switches – NEMA 4 approved
- Aluminum with corrosion-resistant chromate conversion coating
- Ranges from 7 to 7,000 psi
- Diaphragm and pivot seal models
