型号：ZRC-HYA阻燃通信电缆，WDZ-HYA无卤阻燃通信电缆，ZR-HYA阻燃通信电缆，MHYA矿用通信电缆技术特点：防火阻燃低损耗低色散结构紧凑良好的综合机械性能应用范围：适用于矿山、电厂、市内、近郊及局部地区，起到防火阻燃作用。
When the data is transmitted at a high speed, the transmission line effect appears. At this point, the characteristic impedance of the load must match the output, otherwise, the echo will reflect and cannot work normally. Even though in some cases, can be done by resistance in the end of the parallel matching impedance matching, but in the long run, when the resistance change and come back down for some reason, besides, the disadvantages of this also leads to increased power consumption.
一、产品执行标准:企业标准Q/TY二、低烟无卤电缆的说明低烟无卤电缆可分为低烟无卤阻燃系列和低烟无卤耐火系列。低烟无卤电缆是本公司参照法国标准RCCE及NF系列标准、国家标准GB/T18380、GB/T19216、GB/T17651、GB/T17650及进行生产。
原理简介51单片机内部有一个全双工串行接口。什么叫全双工串口呢?一般来说，只能接受或只能发送的称为单工串行;既可接收又可发送，但不能同时进行的称为半双工;能同时接收和发送的串行口称为全双工串行口。串行通信是指数据一位一位地按顺序传送的通信方式，其突出优点是只需一根传输线，可大大降低硬件成本，适合远距离通信。其缺点是传输速度较低。与之前一样，首先我们来了解单片机串口相关的寄存器。SBUF寄存器：它是两个在物理上独立的接收、发送缓冲器，可同时发送、接收数据，可通过指令对SBUF的读写来区别是对接收缓冲器的操作还是对发送缓冲器的操作。

产品型号：WDZ-RYY低烟无卤多芯电缆电缆结构：导体：无氧裸铜丝绝缘：低烟无卤环保型护套：低烟无卤环保型颜色：黑色(RAL9005)灰色(RAL7001)工作电压：450/750V测试电压：＜0.5mm²：2000V≥0.5mm?：2500V使用温度范围：-20℃~+90℃小弯曲半径：12x电缆。
Electronic computer shielded cable, choose high pressure polyethylene insulation, small dielectric constant use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure, with a small dielectric loss, transmit ability strong, good anti-jamming performance characteristics, can be reliably transmitted weak the analog signal or digital signal, can be widely used in electricity, metallurgy, petroleum, chemical, textile and other departments of detection and control computer system or automated devices, as well as general industrial computer. High-temperature F46 computer cable belong to one of the special cable, electronic computer system is in urgent need of modern industrial construction of form a complete set of products, it is widely used in energy industry, metallurgical industry and petrochemical industry and other industrial enterprises and scientific research department of the electronic computer, instruments and meters, all kinds of automatic detection e, and other information processing e signalling and the control system. Application: it is installed in indoor, cable trench, pipe and other places where high temperature resistance electrostatic shielding is required
小结：我找的接近开关由于没有说明书，又没有查找资料，只有一个型号导致了这个可笑的问题出现。那么我们在遇到没有在产品上标明是PNP还是NPN的时候怎样去用万用表去判定它的类型呢。用万用表直流电压50V档去测量前提是把24V电源接到接近开关上，并用金属器材触发，其次是拿万用表的红表笔接在信号输出线上，黑表笔接在24V-极上，如果没有电压则，那么我们可以去判定是NPN型。如果有这个传感器是PNP型。
2、用途：本产品适用于直流和交流50HZ-60HZ下，额定电压450/750V及以下的控制、信号保护和测量线路。3、产品型号规格及范围：产品型号规格范围使用场合KYV,KYVP,KYVP20.5-10mm2,2-61芯此产品绝缘电阻高，防水性能强，较好的耐寒性，适用于弱电控制系统或强电磁场干扰区。

Power cable installation considerations, characteristics and operation condition 1, power cable installation considerations for cable laying parallel with heat pipe installation to keep a distance of 2 m, when crossing, should keep 0.5 m. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter.
理论上RS485的传输距离能达到1200米，但实际应用中传输距离要小于1200米，具体长度受周围的环境影响。一般推荐如下：普通双绞屏蔽型电缆STP-120Ω（forRS485&CAN）onepair20AWG，电缆外径7.7mm左右。
