This is a high - quality pressure switch, model RT200L. It has a wide range of excellent performance parameters. The maximum test pressure Pe is 25 bar (equivalent to 363 psig), and the highest working pressure is 22 bar (320 psig). The enclosure protection class is IP66, which provides reliable protection in various environments. Regarding the adjustment range, the adjustable range of pressure Pe is from 0.2 bar (2.9 psig) to 6 bar (87 psig), which can meet different pressure control requirements. The contact hysteresis is 0.25 bar. In terms of electrical specifications, it complies with the EN 60947 - 4/-5 standard. The electrical connection is of cable thread type, with a size of 2xPg 13.5, and the connection form is internal thread, following the DIN 40430 standard. For EN 60947 wiring properties, it supports flexible wires with ferrules (0.2 - 1.5 mm²), flexible wires without ferrules (0.2 - 2.5 mm²), and solid / stranded wires (0.2 - 2.5 mm²). Its electrical insulation can reach 400V, the pollution degree is 3, the rated impulse voltage is 4 kV, and it has a short - circuit protection with a 10A fuse. The contact function is SPDT (Neutral Zone), and the contact capacity includes AC15 = 3 A, 400 V; AC1 = 10 A, 400 V; AC3 = 4 A, 400 V; DC13 = 12 W, 220 V; LR = 28 A, 400 V. The pressure connection type is G, with a connection size of 3/8, following the ISO 228 - 1 standard. The pressure connection is male thread (external thread), and the pressure sensing element is a bellows. This product is repairable for the contact system. The ambient temperature range is from - 50 °C (-58 °F) to 70 °C (158 °F), which allows it to be used in a relatively wide temperature range. This pressure switch is an ideal choice for many industrial and commercial applications where accurate pressure control is required.
