Description

OroboPOS-Connector (blue POM), with male connection to OroboPOS head (POS) and with cable and male plug fitting into O2k-Main Unit.

Reference: Product details and purchase information

From OroboPOS-Connector to SmartPOS

In the NextGen-O2k-Series XB and O2k-Series J (introduced in 2023), the OroboPOS-Connector is replaced by the SmartPOS, eleminating the problem of cleaning the electrical connection between sensor head and OroboPOS-Connector.

Functions

The OroboPOS-Connector has several functions:

It presses mechanically the POS against the Glass chamber, ensuring a tight fit.
It connects the POS electronically to the O2k-Main unit transmitting the signal.
In O2k Series A-C it also performs the current to voltage conversion / amplification. For Series D and upwards this function has been incorporated into the O2k-Main unit. For this reason OroboPOS connectors for Series A-C and for Series D-I are NOT interchangeable. The OroboPOS-Connector from O2k-series A-C must only be plugged into or unplugged from the O2k main unit with the O2k switched off.

The OroboPOS-Connector is sensitive to damage by ESD when disconnected from the O2k-Main Unit and when the POS head is removed. Further details: MiPNet14.01_ESD-damage.

Cleaning the body of the OroboPOS-Connector

When experimental media or electrolyte (during service of the polarographic oxygen sensor OroboPOS) leak into the mechanical part of the OroboPOS-Connector, operation of the spring mechanism may be restricted. In such cases, the body of the OroboPOS-Connector should be washed with deionized or distilled water. To do so, screw the OroboPOS head onto the OroboPOS-Connector. Make sure that the plug connecting to the O2k-Main Unit does not get wet (protect with parafilm). Rinse the body of the OroboPOS-Connector with H₂O, pulling the spring-loaded part at the base several times. Salt crystals and media clogging the mechanical part are thus washed out. Wipe off the water while again pulling down the spring-loaded part.

Cleaning the electrical connections

Last update (2023-11-08): To avoid H₂O from penetrating into the OroboPOS-Connector and POS head, the previously mentioned option to remove salt crystals with a paper cloth moistened with H₂O is removed.

Unscrew the OroboPOS and check the electrical connections (the thread of the OroboPOS and the gold pin of the OroboPOS-Connector).
Remove any contaminating grease, salt crystals and moisture with a dry, fine paper cloth.
If the thread of the OroboPOS and the gold pin of the OroboPOS-Connector are discolored or appear stained, clean repeatedly with a fine paper cloth moistened with 99.9 % ethanol until no more traces appear on the paper cloth used for cleaning. It is important to only moisten the paper cloth to avoid EtOH getting into joints which might cause a high leak current. Liquids in joints are difficult to remove and, in many cases, require service by the manufacturer.

Always let the connections (OroboPOS head and OroboPOS-Connector) dry well before use. If the O2k is used in a humid environment or a moistened paper cloth was used for cleaning the connections, the POS-Connector and OroboPOS (without membrane) should be dried in an oven at up to 60 °C for 1-2 h. Follow the procedure with an Oxygen sensor test as a quality control of proper OroboPOS-Connector and OroboPOS performance.

Defective OroboPOS-Connector

If the OroboPOS-Connector has been found to be the reason for a high signal at zero oxygen or a noisy signal, and repeated cleaning and drying of the electrical connections of the OroboPOS-Connector does not solve the problem, it can be sent to our electronics partner for an OroboPOS-Connector Service or needs to be replaced.

If any parts of the OroboPOS-Connector are broken, please contact our technical support.

-=== Cleaning the spring mechanism ===
+:::: When experimental media or electrolyte (during [[MiPNet19.18B POS-service |service of the polarographic oxygen sensor OroboPOS]]) leak into the mechanical part of the OroboPOS-Connector, operation of the spring mechanism may be restricted. In such cases, the body of the OroboPOS-Connector should be washed with deionized or distilled water. To do so, screw the OroboPOS head onto the OroboPOS-Connector. Make sure that the plug connecting to the O2k-Main Unit does not get wet (protect with parafilm). Rinse the body of the OroboPOS-Connector with H<sub>2</sub>O, pulling the spring-loaded part at the base several times. Salt crystals and media clogging the mechanical part are thus washed out. Wipe off the water while again pulling down the spring-loaded part.
-Media outside the chamber or other spills may get into the mechanical part of the POS connector restricting the operation of the spring mechanism hard. The outside of the POS connector should therefore be cleaned with pure water from time to time.
+== Cleaning the electrical connections ==
-Apply a POS to the POS connector and make sure its seal (to the connector) is tight. Leave the POS connector att ched to the O2k-Main Unit or make sure that the plug, which connects the POS connector to the O2k-Main Unit, does not get wet (parafilm, or some other form of shielding). This will ensure that only the outside of the POS connector becomes wet. Then rinse the blue plastic of the connector with pure water, working the spring loaded holder several times (similarly to when inserting the connector into the chamber). This will dissolve any media stuck in the mechanical part of the POS connector.

-Unscrew the POS and check both sides of the electrical connection (the gold pin and thread both on the POS and on the POS connector). Remove any contaminating grease and/or moisture with a fine paper cloth. Soak a paper cloth in ethanol and carefully clean the gold pin and threads. If the gold pin and thread on the POS connector are discoloured or appear stained repeated cleaning with a paper towel soaked in ethanol may be required. Cleaning should be repeated until a fresh paper towel touching the gold pin and threads remains clean. Finally apply a drop of contact oil from your accessories box to each of the golden pins and threads on POS connector and POS. If you have also done a Sensor service or changed the POS membranes allow the O2k to run over night before repeating the Sensor test. If all service precautions fail to solve the problem a new POS connector has to be applied.
