The catalog number 836-NX50 is used for one of the available pressure devices from the 836 Pressure Controls series. The controller is designed and produced by Allen-Bradley/Rockwell Automation. The 836-NX50 pressure controller has a long mechanical life and it provides a typical repeat accuracy of 0.5%. The pressure controls from the 836 series have an operating temperature range of -30 to 66 degrees Celsius (-22 to 150 degrees Fahrenheit) and a storage temperature range of -30 to 93 degrees Celsius (-22 to 200 degrees Fahrenheit). The controllers like the 836-NX50 pressure controller provide both internal and external bellows that are made from either copper alloy or stainless steel (type 316). These devices are typically used for compressed air monitoring systems, air compressors, vacuum transfer systems, and similar applications.

The 836-NX50 pressure controller has a voltage rating of 600 Volts AC and a current rating of 5 Amps. The adjustable differentials of the switches from the 836 series are within the following ranges: 2 to 95 PSI, 0.2 to 125 PSI, and 0.4 to 80 PSI. The average weight of these units is around 3 pounds or 1.3 kilograms. In addition to that, the dimensions of the units are small for devices with such operating ranges. The 836-NX50 pressure controller complies with standards like the NEMA ICS-2, IEC 529/IP2X, UL 698, UL 1604, and others. It should be noted that some of these standards refer to usage in hazardous locations, so the 836-NX50 pressure switch is made for different environments. The manufacturer provides many enclosure options for the pressure devices from the series so that the users can choose a right enclosure for their application.
