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 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

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 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 distilled water, 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

Unscrew the OroboPOS and check the electrical connections (the gold pin and thread on the OroboPOS and OroboPOS-Connector). Remove any contaminating grease and 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, clean repeatedly with a paper towel soaked in water and subsequently in ethanol, until no more traces appear on the paper towel used for cleaning. If the O2k is used in a humid environment, apply a drop of contact oil from the OroboPOS-Service Kit to each of the golden pins and threads on POS connector and POS. Perform an Oxygen sensor test as a quality control of proper OroboPOS-connector and sensor performance.

Replacing the OroboPOS-Connector

If you need to replace the Orobo-POS Connector, an OroboPOS-Connector_Service may be possible.
