This is a high - performance pressure switch designed for various industrial applications. Pressure - related Parameters The maximum test pressure [bar] Pe is 25 bar, and in pounds per square inch gauge (psig), it is 363 psig. The highest working pressure [bar] is 22 bar, and in psig, it reaches 320 psig. The adjustment range [bar] Pe is from 1 bar (14.5 psig) to 10 bar (145 psig), which allows for flexible pressure setting according to different needs. The pressure connection size is 3/8, and it follows the ISO 228 - 1 standard. The pressure connection type is G, with an external thread for pressure connection. The pressure sensing element is a bellows, ensuring reliable pressure detection. Hysteresis The hysteresis of the pressure switch is an important parameter. It ranges from 0.33 bar (4.8 psi) to 1.3 bar (18.9 psi), which helps to prevent frequent switching and ensure stable operation. Electrical Specifications The electrical connection is in the form of a cable thread connection. The electrical connection size is 2xPg 13.5, with an internal thread connection form, complying with the DIN 40430 standard. The electrical specifications are in accordance with EN 60947 - 4/-5. For EN 60947 wiring properties, it supports flexible wiring with ferrule (0.2 - 1.5 mm²), flexible wiring without ferrule (0.2 - 2.5 mm²), and solid / stranded wire (0.2 - 2.5 mm²). The electrical insulation can withstand up to 400V, with a pollution degree of 3. The rated impulse voltage is 4 kV, and it has a short - circuit protection with a 10A fuse. Contact Function and Capacity The contact function is SPDT with gold - plated contacts, which can ensure good electrical conductivity and long - term reliability. The contact capacity is specified as Ci = 0.5 nF, Ii = 0.5 A, Li = 0.2 uH, Pi = 1 W, and Ui = 29 V. Environmental Performance The case protection class IP is IP66, which provides excellent protection against dust and water ingress, suitable for use in harsh environments. The ambient temperature range is from - 20 °C (-4 °F) to 65 °C (149 °F), making it applicable in a wide range of temperature conditions. In summary, this pressure switch combines reliable pressure - sensing performance with excellent electrical and environmental adaptability, meeting the diverse requirements of industrial applications.
