DESCRIPTION

The PFM800-4MP is designed to video signal transmission via twisted-pair cable. The device adapts the impedance of coaxial cable 75Ω to the impedance of symmetrical line, ensuring transmission of video signal up to 400m (twisted-pair cable category 5) and eliminates asymmetric interferences.

It is important to pay attention to linking the adequate terminals: (+) and (-). Reverse connection would cause distortion of image.

    OUR OPINIONS
    • The enclosures are made so that can be joined them to each other.
    • Tiny dimensions allow to easy montage of the transformers even in case of thick BNC sockets mounted.
    • Spring terminals for twisted-pair cable allow to quick assembly without any tools.
    • Due to the large attenuation, it is not recommended to use with a longer twisted pair cable.
