Belden 8918 is a high-performance and shielded twisted pair (STP) cable used in Ethernet and audio/video networks. It features a four-pair aluminum foil and braid shield for superior noise rejection, plus four stranded 24 AWG bare copper conductors. This cable has been tested to 500 MHz of data transmission and is suitable for use in power-limited circuits, in addition to high-speed data transmissions such as 10BASE-T, 100BASE-TX, 1000BASE-T, and ATM. Belden 189100 is a non-shielded multi-conductor cable with overall foil shield and PVC jacket. It features two twisted 24 AWG conductors plus aluminum mylar shield and a PVC outer jacket. This low-profile, flexible cable is suitable for use in 10/100 Ethernet, power limited controls, analog audio, security & surveillance systems, and EIA-485 networks.
