The Bosch Rexroth HM 20-2X/400-H-K35 (R901342034) is a high-performance pressure transducer designed for dynamic pressure control in hydraulic systems. It features a thin-film measuring cell and delivers an analog output of 0.5 to 4.5 V, with a rapid signal rise time of less than 2 ms, ensuring swift response times suitable for real-time monitoring applications. The unit can measure pressure ranges up to 400 bar, making it versatile for various industrial applications. This model is engineered with robustness in mind; all components that come into contact with the media are constructed from stainless steel, offering durability and resistance to corrosion. It boasts a high degree of measurement accuracy of less than ±0.25% FS and demonstrates excellent overload and bursting behavior, enhancing operational safety. The HM 20-2X/400-H-K35 is equipped with a G1/4 hydraulic connection and includes a throttle element in the pressure channel. For secure electrical connections, it utilizes a connector pole M12x1, A-coded according to EN standards. The device operates on a supply voltage of 10 to 30 VDC and has a weight of approximately 0.2 kg. Its NBR seals are compatible with hydraulic fluids such as HL, HLP, HFC, and Nitrogen up to 400 bar. In terms of conformity and certifications, this model complies with CE marking for electromagnetic compatibility per EU directives and RoHS regulations for hazardous substances. It also carries UL recognition for safety and quality assurance. The HM 20-2X/400-H-K35 does not include a display but offers an extensive operating temperature range from -40°C to +125°C. Additionally, it has received marine approval from DNVGL for all variants with current output, indicating its suitability for maritime applications as well as other demanding environments where precise pressure measurement is critical. This component belongs to series X and can handle maximum operating pressures up to 630 bar across various pressure ratings including but not limited to 100, 160, 250, and 400 bar options while being cULus-listed for compliance with North American safety standards.
