The Bosch Rexroth HM 20-2X/250-H-K35-N (R901456333) is a high-precision pressure transducer designed to provide reliable and accurate pressure measurements in a variety of industrial applications. This model features an analog output of 0.5 to 4.5 V, making it compatible with numerous control systems and devices. The unit is capable of measuring pressure ranges up to 250 bar, ensuring versatility across different hydraulic systems. Equipped with a robust thin-film measuring cell, the HM 20-2X/250-H-K35-N ensures excellent measurement accuracy of less than ±0.3% FS (Full Scale). The device's components that come into contact with media are constructed from stainless steel, enhancing its durability and suitability for use with various hydraulic fluids such as HL, HLP, HFC, and Nitrogen up to 350 bar. This model boasts rapid signal rise times of less than 2 ms, enabling dynamic pressure control in fast-changing environments. It also features a G1/4 hydraulic connection and includes a throttle element in the pressure tube for improved response times. Safety is paramount with this transducer as it showcases superior overload protection and bursting behavior, ensuring operational security even under extreme conditions. The electrical connection is facilitated through a connector pole M12x1 A-coded in accordance with EN standards. The Bosch Rexroth HM 20-2X/250-H-K35-N does not have a display but offers a supply voltage requirement of 8 to 30 VDC and weighs approximately 0.4 kg. Its seals are made from NBR material to maintain integrity under varying conditions. For compliance assurance, the transducer meets CE electromagnetic compatibility requirements under EU legislation, RoHS Directive EU standards for hazardous substances, UL recognition for safety standards in North America, and UKCA marking for conformity in the United Kingdom. Additionally, it holds marine approval DNVGL for all variants with current output which speaks to its reliability in marine applications where rigorous standards are observed.
