　　同样的道理，如果有屏蔽线起到屏蔽作用的话，外部干扰源对于其的干扰影响也可以尽可能的缩小。3.选择使用普通的超五类屏蔽双绞线即网线就可以。由于原材料价格上涨，导致现在市场上的线材鱼龙混杂，有不良商人利用某种合金来顶替铜丝来做网线，在外面镀铜以蒙混客户。

　　4、使用特性：电缆导体的长期允许工作温度为70℃，电缆敷设温度应不低于0℃。电缆允许的弯曲半径：对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。对有屏蔽层结构的软电缆，应不小于电缆外径的6倍。对无铠装层的电缆应不小于电缆外径的6倍。



Propane burner plane with the flame of 750 ℃ and contact sample, sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical flame combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on his own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.

工作原理读卡器以固定频率向外发出电磁波，频率一般是13.56MHZ，当感应卡进入读卡器电磁波辐射范围内，会触发感应卡上的线圈，产生电流并触发感应卡上的天线向读卡器发射一个信号，该信号带有卡片信息，读卡器将电平信号转换成数字序号，传送给就地控制器，就地控制器将信息上传给上层控制器，终上传给门禁服务器，门禁服务器将卡号与数据库内的信息进行比对，从而得到全部的卡片信息。安装注意事项1.上电之前必需确认电源的电压(DC9V-DC15V)和电源的正负极；2.当使用外接电源时，建议与控制器电源共用电源地线(GND)；3.读卡器到控制器的线建议用8芯屏蔽多股双绞网线。

　　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。工作温度：电缆长期允许工作温度不超过70℃。芯数从2芯到24芯之间按国标分色，两芯以上绞合成缆，外层绞合方向为右向，软圆无氧铜线或镀锡无氧铜线屏蔽，广泛应用于仪器、仪表、楼宇对讲、监视监控的控制安装。


　　这种区别是由历史原因造成的，而不是由于技术原因或生产厂家。同轴电缆的这种结构，使它具有高带宽和极好的噪声抑制特性。同轴电缆的带宽取决于电缆长度。1km的电缆可以达到1Gb/s~2Gb/s的数据传输速率。

Tianjin cable pull branch factory in line with the principle of "customer is", with "honest, trustworthy, thoughtful" service concept won the trust of the extensive business.

对于接触器KM2，由于工作的要求，不需自保持，当SB3松开，电动机M2即停转。停车只要按下停止按钮SB1。SB1串联在KM1和KM2电路中。按下停止按钮SB1，电路开路，接触器KMKM2失电，使主电路中的接触器主触点断开，电动机失电。当再起动时，必须重新按下起动按钮SBSB3。综上所述，电动机的起动由接触器或断电器控制，而接触器或继电器的吸合或释放则由开关或按钮控制。这种开关或按钮接触器或继电器电动机的控制形式，就是机械自动化的基本形式。
