Mechanical Pressure Switch 625 -900 ... 6000 mbar

Product catalog summary

Overview: The Huba Control type 620 and 625 pressure switches are designed for use with liquids and gases, offering 13 pressure ranges from -4 to -900 mbar and 2 to 6000 mbar. These switches are available with bodies made from plastic, brass, or aluminum, and diaphragms made from NBR, FPM, EPDM, or silicone. They are noted for their high precision, long-term stability, and rugged design, making them suitable for industrial equipment, process technology, and food automation.

Specifications:

Pressure Range: Relative pressure from 2 to 6000 mbar and negative pressure from -4 to -900 mbar.
Operating Conditions: Suitable for liquids and neutral gases with temperature ranges depending on diaphragm material (e.g., NBR: 0 to +80°C, Silicone: -40 to +80°C).
Materials: Case made of fiberglass-reinforced plastic; contact materials include NBR, EPDM, FPM, and silicone.
Electrical Specifications: Nominal voltage of 250 VAC, with different current ratings for resistive and motor loading. The contact system is a changeover contact with a mechanical service life of 10⁶ switching cycles.
Protection Standard: IP 00 without cover, IP 54 with cover.

Technical Features:

Adjustable switching differences and customer-specific switching points.
High accuracy with repeatability of switching points less than 0.3 mbar for NBR and silicone diaphragms.
Pressure connections vary by type, including M5/M12x1 threads and G ⅛, G ¼ threads.

Order Information: The document includes order code selection tables for types 620 and 625, detailing pressure modes, ranges, and diaphragm materials. Accessories such as mounting brackets and connector sets are also listed.

Contact Information: Huba Control has offices in Switzerland, Germany, France, the Netherlands, and the UK, with contact details provided for each location.
