RS-485W NET CABLES
1. Product Description
RS-485W are developed and upgraded from RS-232、RS-422 communication protocol cables. They have outstanding products
properties and can replace RS-232、RS-422 type products. They can be used in all kinds of complicated industrial automation
control network communication. They can
be in the two lines and four lines way. It will achieve really multipoint two-way communication if they are
in the two lines way.

4. Product features
Having good anti-jamming performance, they can be used in all kinds of complicated industrial
automation control network
communication.
It is very convenient to be used in multiple spot connections. They can support 32 drivers and 32 receivers.
They have overlong transmission range. They can transfer signals 1200 meters. If you magnify signals by using
relay, you can add 8 relays at most and the transmission range can be 9600 meters.
Characteristic impedance is 120 Ohm. Cables have independent TC earth conductor in add. They are special
purpose cables for transmission of RS-485、RS-232、RS-422 communication protocol.
About laying condition, they can meet the environmental requirement : -40℃~90℃
Minimum bending radius ＞10D
Armored double screened cables can be used in seriously jamming, frequently rodent places and sites where the
lightning protection and anti-explosion needs have. Minimum bending radius＞15D
