Bosch Rexroth HM 20-2X/630-C-K35-N electronic pressure transducer

HM 20-2X/630-C-K35-N, manufacturer material number R901342035, is a Bosch Rexroth HM20 electronic pressure transducer with a 630 bar measurement-range class, male G1/4 process connection and two-wire 4–20 mA current output. It converts hydraulic pressure into an analog electrical signal.

The supply range is 18–36 V DC, limited to 30 V DC for cULus applications. The current-output load relation is RA = (US − 8.5 V) / 0.0215 A, with RA in ohms and US in volts. The stated full-span characteristic-curve deviation includes non-linearity, hysteresis and zero/end-value deviations. Electrical supply, medium compatibility and protection against hydraulic pressure peaks must be checked for the installation.

The selected manufacturer technical reference is RE30272, edition 2022-02. Its separate overload reference is 1000 bar and burst reference is 2520 bar. Neither value is a permissible continuous measurement range.

The electrical mating connector and any optional cable or mounting accessories must be selected separately; their illustration does not establish inclusion with this article.
