There is no standard or widely recognized wire type called "PCNTR wire." It's possible that this is a specific, non-standard term used in a particular context, like within a company or project.

To help you understand what you're looking for, please provide more context:

* Where did you encounter this term? (e.g., a product manual, wiring diagram, technical document)

* What is the surrounding context? (e.g., what is the purpose of the wire, what kind of device is it used with)

* Are there any other clues? (e.g., is there a number or symbol associated with it)

With more information, I might be able to help you identify what "PCNTR wire" actually refers to.
