This is a high - performance pressure switch, model MBC 5100. It is suitable for a wide range of applications and comes with a series of reliable parameters. Pressure - related Parameters The adjustment range of pressure (Pe) is from 5 bar to 40 bar. In terms of pounds per square inch gauge (psig), although not directly provided in the original in this unit for the adjustment range, it can be calculated for reference. The maximum test pressure [bar] Pe is 150 bar, and in pounds per square inch gauge, it is 2176 psig. The highest working pressure [bar] is 150 bar, and the highest working pressure [psig] is 2175 psig. The pressure connection size is 1/4, with the connection type being G. The pressure connection standard follows ISO 228 - 1. It has a pressure connection with a note of "with flange". The differential pressure at the maximum range setting is 7 bar, and at the minimum range setting is 2 bar. The burst pressure [bar] is 300 bar. Environmental and Protection Parameters The enclosure protection class is IP65, which means it has a high - level protection against dust and water ingress. The environmental temperature range is from - 10 °C (14 °F) to 85 °C (185 °F). Electrical Parameters The electrical specification standard is EN 60947 - 5. The electrical connection is a DIN plug with a size of M20 and in - thread connection form (both male/female). The electrical connection standard is EN 175301 - 803 - A. The contact function is SPDT (Single - Pole Double - Throw), which provides flexible electrical switching options. The contact capacity is AC15 = 0.5 A, 250 V and DC13 = 12 W, 125 V. Other Features It has an automatic reset function. Regarding the repairability, it is marked as "numbered", indicating a certain level of maintainability. This pressure switch has passed multiple certifications such as ABS, BV, CCC, CCS, CE, CMIM, DNV, EAC, GL, KRS, LLC CDC EURO - TYSK, LR, LVD, NKK, RINA, RMRS, RoHS, and RoHS China, ensuring its quality and compliance with international standards.
