The Bosch Rexroth HM 20-2X/400-H-K35-N (R901466598) is a high-performance pressure transducer designed for dynamic pressure control in hydraulic systems. This robust sensor is capable of measuring pressures up to 400 bar with a fast signal rise time of less than 2 ms, ensuring timely and accurate readings for real-time applications. The HM 20-2X/400-H-K35-N features a thin-film measuring cell and all media-contacting components are constructed from durable stainless steel, which provides a high degree of measurement accuracy of less than ±0.5% FS. The unit's excellent overload and bursting behavior make it suitable for demanding environments where operational safety is critical. It offers protection against reversed polarity, overvoltage, and short circuiting, which contributes to its reliability. The analog output of 0...10 V from the transducer allows for easy integration into existing control systems. With an operational temperature range from -40°C to +125°C, the HM 20-2X/400-H-K35-N is versatile enough to function effectively in varied climates and conditions. It comes with an M12x1 A-coded connector as per EN 175301-803 standards for the electrical connection and has no display component. The supply voltage required is 24 VDC, and the unit weighs approximately 0.4 kg. This sensor uses NBR seals and can handle hydraulic fluids such as HL, HLP, HFC, as well as nitrogen up to pressures of 400 bar. It meets several conformity standards including CE for electromagnetic compatibility, RoHS Directive EU for hazardous substances, UL recognition for safety standards in North America, and UKCA marking post-Brexit. Additionally, it has received marine approval from DNVGL when used with current output options, highlighting its suitability for maritime applications where reliable pressure measurement is essential.
