NPN三极管和输出NPN型三极管，要导通，需要满足VCVBVE，其中VC，VB，VE分别是集电极，基极和发射极的电压，一般使用NPN三极管做输出的时候，往往把三极管接成OC输出，也就是让集电极C开路的输出，而射极E接地，基极B是控制信号控制输入端。上图是一张NPN输出的示意图，左边是传感器内部结构，已经加了上拉电阻R2了，当IO处输入高电平，三极管导通，OUT处的电位几乎和地端一样，所以OUT输出低电平。

Purpose: the self-supporting non-filled cable is suitable for the urban and township telecommunication lines of local telecommunication network, and also for the special network lines connecting to the public network. It is economical and practical to use the same outer protective layer for hoisting line and cable. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C. Structure: wire: annealed bare copper wire, copper wire diameter is 0. 4, 0. 50, 0. 60, 0. 70, 0. 80, 0. 90 mm. Insulating material: high density polyethylene or ethylene-propylene copolymer. The color of the insulated wire is in accordance with the full chromatographic standard. Pair of insulated wires: two different colored insulated wires are twisted in pairs according to different pitch and are identified by a specified chromatographic combination. Core structure: with 25 pairs as the basic unit, more than 25 pairs of cables are assembled according to the unit, each unit is wired with the unit of specified chromatogram to identify different units. 100 pairs or more of cables plus 1% of the reserve pair. Core tape: wrap with a polygrease film tape. Shielding: the two sides are overlapped with or without corrugated metal strip, beyond the cable core of the longitudinal capsule. The plastic film coated on the surface of the shielding belt and the bonding sheath of the protective layer: black low density polyethylene. Hoisting line: the hoisting line is 7 strands of galvanized steel strand, nominal outside diameter is 6. 3 and 4 mm. The tensile strength of two types of 75mm is not less than 3000kg and 1800kg respectively. The suspension wire is coated with thermoplastic paint to prevent the steel wire from corrosion.

铠装通信电缆结构：1、基本电缆：任何单护套或双护套结构的填充型和非填充型电缆。 2、铠装通信电缆机械保护层：53型采用0.15mm厚的轧纹钢带，纵包于基本电缆之上，两边搭接。钢带表面经涂塑处理，以防腐蚀和水份侵入。
本厂生产的射频电缆的结构是多种多样的，可以根据不同的方式和型式来分类。射频电缆按结构分类（1）同轴射频电缆同轴射频电缆是最常用的结构型式。由于其内外导体处于同心位置，电磁能量局限在内外导体之间的介质内传播，因此具有衰减小，屏蔽性能高，使用频带宽及性能稳定等显著优点。

二是加强现场安全管理。严格履行“两票”规定和安全技术交底规定，尤其是动火作业严格履行“动火工作票”规定，落实安全技术措施。规范外包单位焊接、电工作业，在可能出现火灾的区域设置灭火器，对施工现场易燃易爆物品进行清理，划定易燃易爆危险品的存放区域，保持与明火作业面25m的防火间距。三是加强外包作业人员尤其是特殊工种人员（焊工、电工）安全教育、安全交底和风险告知，提高不同单位、不同班组作业人员的安全意识，强化“互不伤害”意识。
导体：多股铜导体，符合GB/T3956第5类（等同于IEC60228.5）。绝缘：聚氯乙烯混合料（PVC）。护套：柔性聚氯乙烯混合料（PVC），灰色（RAL7001）。芯线标识：≤5芯，彩色芯线；黑色芯线白色数字编号，黄绿地线。
