HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.

交流接触器尤其是电磁式接触器，是我们电工工作中极为常见常用的一种电气控制器件。
至于其工作原理和结构特点，相信广大同行们都是相当熟悉。
可大家在使用过程中，不知注意到一种现象没有——在触点容量低于60A的交流接触器中，其吸合线圈工作电源多直接使用交流电源（多见AC380V、220V、36V三种电压等级）；而一旦接触器触点容量高于60A后，其吸合线圈工作电源则多变成直流形式（也是引入交流电源但已经经过整流电路转换）。
目前，随着科技水平的不断提高，阻燃问题已由过去的卤素阻燃化，发展到低卤、无卤的阻燃化。

低烟无卤线材配方添加材料：(1)选用线型PE及弹性PE为主要树脂，阻燃材料选用三种含结晶水的金属氧化物：分别为在200℃、300℃、300℃以上失去结晶水。
低烟无卤电缆技术发展低烟无卤阻燃线缆料的市场技术现状与发展趋势含卤(特别是溴系)阻燃聚合物体系因其突出的阻燃效果，80年代中期以前在阻燃聚合物市场中占有**的统治地位。
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。
信号输入引脚：作用是将输入信号引入集成电路。
具有一个信号输入引脚的集成电路一般在引脚旁标注“IN”字符。
如果具有同相和反相两个输入引脚，则在引脚旁分别标注有“＋”“－”字符，如下图：集成电路输入引脚的外电路特征是，通过一个耦合元件与前级电路的输出端相连接。
这个耦合元件可以是耦合电容C，或者是耦合电阻R，或者是RC耦合电路，或者是耦合变压器T等。
有些集成电路具有多输入信号引脚。
如下图：振荡器、函数发生器等信号源类集成电路一般没有信号输入引脚。
