OroboPOS-Connector

O2k-Catalogue

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

Two units of this item are standard components of the O2k-Assembly Kit (O2k-Core), mounted on the OroboPOS-Holders at the O2k-Main Unit.

Functions

The OroboPOS-Connector has several different functions:

  • It mechanically presses the POS against the glass chamber, ensuring a tight fit.
  • It connects the POS electronically to the 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 Main unit. For this reason OroboPOS connectors for Series A-C and for Series D are NOT interchangeable.

The OroboPOS-Connector is particular 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 spring mechanism

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. Apply a POS to the POS connector and make sure its seal (to the connector) is tight. Leave the POS connector attached 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. After this sort of cleaning, the POS connector should not be used for 1-2 days in order to dry properly.

Cleaning the electrical connections

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.
