The Bosch Rexroth HM 20-2X/160-C-K35-N (R901381345) is a high-precision pressure transducer designed for dynamic pressure control in hydraulic systems. This robust sensor features an analog output of 4...20 mA, suitable for a pressure range up to 160 bar, and is equipped with a G1/4 hydraulic connection. The throttle element ensures a short signal rise time of less than 10 ms, which is crucial for applications requiring rapid response times. All components of the HM 20-2X/160-C-K35-N that come into contact with the media are constructed from durable stainless steel, offering excellent resistance to corrosive fluids and ensuring longevity in harsh environments. The device boasts a high degree of measurement accuracy of less than ±0.5% FS and showcases outstanding overload and bursting behavior, making it reliable for safety-critical applications. The thin-film measuring cell at the core of this sensor provides precise measurements with an accuracy class of 0.5 and non-repeatability less than 0.1%. It operates within a wide temperature range from -30°C to +80°C and has been granted marine approval by DNVGL, confirming its suitability for maritime applications. This model features an M12x1 electrical connection with A-coding according to EN standards, ensuring compatibility with industry-standard connectors. Its design conforms to CE standards for electromagnetic compatibility, as well as the RoHS Directive for hazardous substances, cULus listing, UL recognition, and UKCA marking. With its maximum operating pressure capability of up to 600 bar across various pressure ratings (40, 100, 160, 250, 315, 400, and 600 bar), the HM 20-2X/160-C-K35-N is versatile for different system requirements. It also supports various hydraulic fluids like HL,HLP,HFC,Nitrogen up to 350 bar. The unit's weight is approximately .4 kg and comes without a display but includes seals made from NBR (Nitrile Butadiene Rubber), providing reliable sealing performance in typical industrial conditions. The supply voltage required for operation is set at standard industrial levels of +24 VDC.
