• Self-Describing technology for quick, easy setup
• Measurement range of 0 to 20.1 mA
• Accuracy of ±0.001 mA ± 0.2.% of absolute current
• Cable length: 182.88 cm (72 in)
• Locking jack to ensure sensor is connected and stays connected

The HOBO SD-MA-420 is a self-describing 4-20 mA input cable sensor for use with the HOBO MX1104 and MX1105 Multi-Channel Data Loggers. Integrated strain relief ensures the probe is secured to the logger. The SD-MA-420 features self-describing technology to automatically communicate configuration information to the logger without any programming or extensive user setup.

The SD-MA-420 measures currents from 0 to 20.1 mA and must be connected so that the current flows through, and with the proper polarity, as shown below. Do not expose to current above 20 mA or negative current. Do not cut off the end of the black cable where it connects to the blue and yellow wires as that contains the precision resistor required for current measurements.
