The Bosch Rexroth HM 20-2X/100-C-K35-N (R901342024) is a high-performance pressure transducer designed for dynamic pressure control in hydraulic systems. This sensor excels in transforming measured pressure into a linear, analog electrical signal of 4-20 mA, suitable for accurate monitoring and regulation tasks. It features a robust design with all components that come into contact with media being constructed from durable stainless steel, ensuring longevity and reliability even in harsh conditions. The HM 20-2X/100-C-K35-N is equipped with a thin film measuring cell that provides high measurement accuracy of less than ±0.5% FS and excellent non-repeatability of less than ±0.1%. It has been engineered to offer rapid signal rise times below 2 ms, which is critical for systems requiring fast response times. The device can handle pressure ranges up to 600 bar and includes an integrated throttle element in the pressure channel to stabilize the signal. For ease of electrical connection, this model includes a connector pole with M12x1 A-coding according to EN standards. The absence of an onboard display streamlines the unit's profile while the supply voltage requirement is standard at 24 VDC. With a weight of just 0.6 kg and NBR seals, it is designed for straightforward installation and maintenance. Safety features are paramount; this transducer boasts excellent overload protection, reversed polarity protection, overvoltage protection, and short-circuit protection. Its operational safety is further enhanced by its high bursting pressure capability. The HM 20-2X/100-C-K35-N operates efficiently within a wide temperature range and meets various conformity standards including CE, UL, UKCA, RoHS, and DNV marine approval for variants with current output. The component series X ensures compatibility across different applications with maximum operating pressures up to 600 bar and various pressure ratings available (from 50 bar up to 600 bar). This transducer is cULus-listed, confirming its compliance with North American safety standards.
