This is a high - performance pressure switch named RT6AES. It has a wide range of excellent features designed to meet various industrial needs. The adjustment range of this pressure switch is quite flexible. The adjustment range [bar] Pe is from 10 bar to 28 bar (equivalent to 145 psig - 406.1 psig in pounds per square inch gauge pressure). This allows for precise control according to different application requirements. The hysteresis is 1.5 bar (14.5 psi), which ensures stable operation and prevents frequent switching fluctuations. In terms of pressure connection, the pressure connection type is G, and the pressure connection size is 3/8. The pressure connection standard follows ISO 228 - 1. It should be noted that a welding reducing pipe of 6.5/D10mm is required for connection. The pressure connection is male - threaded (External Thread), and the pressure sensing element is a bellows. Regarding the performance under pressure, the maximum test pressure [bar] Pe is 38 bar (551 psig), and the highest working pressure [bar] is 34 bar (495 psig). The switch also has a high - level protection function. The enclosure protection class is IP66, which provides reliable protection against dust and water ingress, suitable for use in harsh environments. The fluid group is 1, and the switch can withstand a high burst pressure of 136 bar. For the electrical part, the electrical connection is in the form of cable thread connection, with a size of 2xPg 13.5 and an internal - threaded connection (Female/Male: Internal Thread). The electrical connection standard complies with DIN 40430, and the electrical specification standard is EN 60947 - 4/-5. In terms of electrical properties, it has good insulation performance with an insulation of 400V, a pollution degree of 3, and a rated impulse voltage of 4 kV. The short - circuit protection is provided by a 10A fuse. The EN 60947 wiring properties include flexibility, with a ferrule applicable for 0.2 - 1.5 mm², without a ferrule applicable for 0.2 - 2.5 mm², and applicable for solid or stranded wires of 0.2 - 2.5 mm². The contact function is SPDT with gold contacts, which can ensure reliable electrical connection. The contact capacity parameters are Ci = 0.5 nF, Ii = 0.5 A, Li = 0.2 uH, Pi = 1 W, and Ui = 29 V. The switch is applicable within a certain environmental temperature range. The minimum environmental temperature is - 20 °C (-4 °F), and the maximum is 65 °C (149 °F). It is listed in the catalog IV and has passed multiple certifications such as ATEX, CCC, CE, EAC, etc., which fully demonstrates its high - quality and compliance. The contact system of the switch is repairable, providing convenience for maintenance and reducing long - term use costs.
