Cable properties


Neutrik is an international corporation with about 40 years of know-how and experience in the manufacture of innovative electrical and electronic interconnection products and systems.


Shrink sleeves are meant to protect company logo’s or cable tags, they are factory installed for the purpose of placing a cable tag without the need to detach the connector. The heat shrink tubing can be easily shrunk by means of a heat gun. The sleeves are not lined with glue and have a length of 60mm. To achieve the most optimal care for your cable connection the sleeve is best to be placed 30 cm from the connector.


The flexible and solid PVC outer jacket makes it the perfect cable for many kinds of applications. The smooth outer jacket provides great and easy pulling capabilities to guide the cable through a truss or around a corner while still offering perfect rolling and unrolling performance for highly demanding mobile applications.
