This is a high - performance pressure switch with model number RT6AEW. It has a wide range of excellent features to meet various industrial needs. Pressure - related Parameters The maximum test pressure [bar] Pe is 38 bar, and in pounds per square inch gauge (psig), it is 551 psig. The highest working pressure is 34 bar (495 psig), ensuring reliable operation under normal working conditions. The adjustment range [bar] Pe varies from a minimum of 5 bar to a maximum of 25 bar. In terms of pounds per square inch gauge, the adjustment range Pe is from 72.5 psig to 362.6 psig. The pressure switch has a hysteresis of 3 bar (43.5 psi), which helps to prevent frequent switching and ensure stable operation. The pressure connection size is 3/8, with a connection type of G and a connection standard of ISO 228 - 1. The pressure 公头 / 母头 is an external thread, and the pressure sensing element is a bellows. There are some pressure connection precautions, such as welding a reducing pipe of 6.5/D10mm. Electrical Parameters The electrical connection is of the cable thread type, with a size of 2xPg 13.5 and a connection form (公头 / 母头) of internal thread, complying with the DIN 40430 standard. The electrical specifications are in accordance with EN 60947 - 4/-5. Regarding EN 60947 wiring properties, for flexible wires with ferrules, the applicable wire size is 0.2 - 1.5 mm²; for flexible wires without ferrules, it is 0.2 - 2.5 mm²; and for solid or stranded wires, it is 0.2 - 2.5 mm². The electrical insulation is rated at 400V, with a pollution level of 3, a rated impulse voltage of 4 kV, and short - circuit protection by a 10A fuse. The contact function is SPDT with gold - plated contacts, and 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. Other Parameters The case protection level is IP66, which provides excellent protection against dust and water ingress. The fluid group is 1, and the burst pressure [bar] is 136 bar. The environmental temperature range is from - 20 °C (- 4 °F) to 65 °C (149 °F), allowing it to be used in a variety of environmental conditions. The product is approved by multiple certifications such as ATEX - Cat. 2 - Zone 1, CCC, CE, EAC, etc., ensuring its compliance with international standards. It comes in a multi - pack packaging with 15 pieces per pack. The product is also repairable, specifically the contact system. The product's catalog number is IV.
