1419A

Belden1419AThe Belden 1419A cable for low capacity computers is mainly produced according to the EIA (Electronic Industries Association) RS-232/422 standard. This cable is 24AWG (7x32) multi stranded tinned copper with FPE insulation medium. It is covered with a Beldfoil shielding jacket and has a 24AWG multi stranded tinned copper grounding wire with a characteristic impedance of 100 ohms and an industrial gray PVC outer sheath. Compliant with UL Style 2919 (30 V 80 ° C) document specifications. Is Datalene used as the insulation material? The insulation characteristics include low dielectric constant and loss tangent, which have undergone high-speed and low distortion data processing. Physical properties include good compressive strength and relatively light weight. Working temperature range: -20 ° C to+80 ° C. Recommended tensile strength: 9.98KG. The color combination for wire pairs is white/blue stripes and orange/white stripes. Length: 305M with a cross-sectional area of 0.20 (mm2) and a resistance value of 89.4 (W/km) per kilometer. The RS-422 standard, also known as "Electrical Characteristics of Balanced Voltage Digital Interface Circuits," defines the characteristics of interface circuits. Actually, there is also a signal ground wire, a total of 5 wires. Since the receiver adopts high input impedance and the transmission driver has stronger driving ability than RS232, it is allowed to connect multiple receiving nodes on the same transmission line, and * * * can connect more than 256 nodes. RS-422 supports point to many bidirectional communication, as there is one master device and the rest are slave devices that cannot communicate with each other. The input impedance of the receiver is 4k, so the load capacity of the transmitter is 10 × 4k+100 Ω (terminating resistance)
