Pressure Switch hex 27

Product catalog summary

Technical Specifications:
The pressure switch hex 27 is equipped with changeover switches that have either silver or gold contacts. It maintains temperature stability across various diaphragm/seal materials, including NBR, EPDM, FKM, Silicone, and HNBR, each with specific temperature ranges. The switch supports a frequency of 200 operations per minute and has a mechanical life expectancy of 1 million cycles for pressures up to 50 bar. It features a pressure rise rate of ≤ 1 bar/ms and factory preset hysteresis adjustable between 10-30%, except for types 0140/0141. The device is vibration resistant up to 10 g and shock resistant up to 294 m/s², with an IP65 protection rating when a suitable connector is installed.

Electrical Specifications:
The pressure switches operate at various voltages and currents, with a rated insulation voltage of 300V and a rated operating current of 2.5 kV. They are suitable for both AC and DC applications and are RoHS compliant, bearing the CE mark for conformity with the Low Voltage Directive 73/23/EC.

Accessories and Applications:
Available accessories include socket devices for increased protection, thread adapters, and socket devices with indicator lights. The switches are suitable for voltages up to 250V and come with various thread connections.

Materials and Construction:
The body is constructed from zinc-plated steel (CrVI-free) with integrated changeover switches and silver contacts. The switches are overpressure safe up to 600 bar and come with adjustable hysteresis, factory pre-set switching points, and ready-wired versions.

Safety and Compliance:
The switches are designed for high overpressure safety and long life expectancy, even under harsh conditions. They comply with RoHS and CE standards. Users must adhere to relevant safety regulations, especially when using oxygen, and should not exceed a maximum operating pressure of 10 bar (50 bar for stainless steel enclosures).
