HM 20-2X/315-F-C13-0,5-N Pressure Transducer R901342038

The Bosch Rexroth HM 20-2X/315-F-C13-0,5-N pressure transducer, material number R901342038, is a hydraulic pressure sensor used for monitoring and controlling pressure in hydraulic systems. It belongs to the Bosch Rexroth HM20 pressure transducer series, which is designed to convert measured hydraulic pressure into a normalized electrical output signal for machine control, monitoring and diagnostics. For accurate purchasing and replacement, the complete model and material number should always be used together: HM 20-2X/315-F-C13-0,5-N / R901342038.

According to Bosch Rexroth HM20 technical data, the HM20 series is used for measuring pressures in hydraulic systems. The series uses a thin-film measuring cell, and components that come into contact with the media are made of stainless steel. The product family is designed for reliable hydraulic pressure measurement, with protection against reversed polarity, overvoltage and short circuit. These features make the HM 20-2X/315-F-C13-0,5-N pressure transducer suitable for demanding hydraulic equipment where accurate pressure feedback is required.

The complete model code HM 20-2X/315-F-C13-0,5-N contains important identification details. The HM20 section identifies the Bosch Rexroth pressure transducer family. The 2X section indicates component series 20 to 29, with unchanged installation dimensions and pin assignments within the same series range. The 315 section identifies the 315 bar pressure measuring range. The final N suffix identifies the version with integrated throttle element, which Bosch Rexroth recommends for applications with dynamic pressure peaks or cavitation effects that may damage the measuring cell.

Bosch Rexroth HM20 technical data lists measurement ranges including 10, 50, 100, 160, 250, 315, 400 and 630 bar. For this specific HM 20-2X/315-F-C13-0,5-N pressure transducer R901342038, the 315 bar range is the key pressure reference. The series data lists accuracy class below 0.5%, hysteresis below 0.15%, long-term drift below 0.1% per year under reference conditions and setting time below 1 ms. These values support stable hydraulic pressure monitoring in industrial control systems.

The electrical and installation data should also be checked before replacement. Bosch Rexroth HM20 data lists an operating voltage of 16 to 36 VDC, or a maximum of 30 VDC for cULus applications. The product family uses a 4-pole M12 connector at the housing. The pressure port is G1/4 according to DIN 3852 form E with seal ring according to DIN 3869-14. The protection class is IP65/IP67 when the mating connector is correctly mounted and locked. Cable sets or mating connectors are not included in the standard scope of delivery and should be ordered separately if required.

The Bosch Rexroth HM 20-2X/315-F-C13-0,5-N pressure transducer is suitable for hydraulic power units, machine tools, presses, plastics machinery, test benches, mobile hydraulic systems, industrial automation equipment and other applications where pressure feedback is needed for control or monitoring. It can be used to support system pressure monitoring, pump control, overload protection, process control and machine diagnostics, depending on the hydraulic circuit and control system design.

For procurement teams and maintenance engineers, the most important purchasing reference is the full Bosch Rexroth model HM 20-2X/315-F-C13-0,5-N together with material number R901342038. Short descriptions such as “HM20 sensor” or “Rexroth pressure transducer” are not enough for accurate replacement. Similar HM20 pressure transducers may differ in measuring range, output signal, electrical connector, throttle element, seal material or special suffix. The full model must remain visible in the product title, description, quotation and purchase order.

Before ordering the Bosch Rexroth HM 20-2X/315-F-C13-0,5-N pressure transducer R901342038, buyers should compare the existing nameplate, pressure range, electrical output, connector type, pressure port and machine documentation. If the sensor is installed on equipment, photos of the nameplate, connector side, pressure port and installed position can help confirm whether this item is the correct replacement. If cable sets, mating connectors or seal rings are required, these should be checked separately.
