Siemens 872C653-091 Thermocouple Rev 5 Sub 5 Sensor

Siemens 872C653-091 Thermocouple Rev 5 Sub 5 Sensor is a Siemens thermocouple assembly designed to measure temperature in industrial automation environments. The part number 872C653-091 and revision label Rev 5 Sub 5 identify a specific sensor configuration within Siemens’ temperature-measurement family, providing a thermocouple signal intended for connection to Siemens measurement hardware and control modules that accept thermocouple inputs. As a genuine Siemens component, it is typically specified when replacing an existing sensor to preserve compatibility with the original wiring, connectors, and documentation. The Rev 5 Sub 5 designation signals Siemens’ ongoing revision cycle for this sensor assembly, reflecting documented updates to form, fit, and interface that maintain consistency with Siemens’ industrial automation portfolio. In practice, it serves as the sensing element in temperature loops across manufacturing equipment and process-control environments where accurate, repeatable readings from a thermocouple are required to drive controllers, alarms, or safety interlocks. Availability is evidenced by listings in industrial catalogs and marketplaces that show the exact model, including used-equipment platforms that reference Siemens 872C653-091 Rev 5 Sub 5.
