English Description
This DeviceNet industrial field bus cable has two main specifications: DVN18 thick cable (15AWG power core + 18AWG signal core) and DVN24 thin cable (18AWG power core + 18AWG signal core), rated voltage 300V. It fully complies with DeviceNet field bus standards and is widely used for automatic networking communication of PLC, servo drives, sensors and industrial robots.
The internal cable structure contains two groups: 2 high-power power supply wires + 1 pair of differential communication signal wires. The signal wires are twisted in pairs, equipped with double shielding of integral aluminum foil shielding layer and tinned copper braid. It effectively resists electromagnetic interference generated by industrial equipment such as inverters and motors, ensuring stable bus signal transmission without communication interruption or signal garbling.
The insulating layer is made of high-quality oil-resistant PVC material, with a gray wear-resistant flame-retardant outer jacket that is bending-resistant, wear-resistant and oil-resistant. The multi-strand stranded conductors feature excellent flexibility, suitable for fixed equipment wiring and simple drag chain mobile wiring scenarios.
Standard full-length reels are in stock, custom cutting and finished cables with pre-crimped terminals/aviation connectors at both ends are available. Custom jacket colors are supported. As direct manufacturer, VAT invoices can be issued, and preferential production schedules are offered for bulk wire harness orders of automation bus projects.
1.Q：DVN18 粗缆和 DVN24 细缆有什么区别，分别适合什么场景？
A：DVN18 粗缆电源芯线径更大，载流能力更强，适用于远距离总线组网、多节点大功率设备；DVN24 细缆线缆外径更小，布线更节省空间，适合短距离、设备内部紧凑型布线。
Q: What is the difference between DVN18 thick cable and DVN24 thin cable, and what scenarios are they suitable for respectively?
A: The power core of DVN18 thick cable has larger wire gauge and stronger current carrying capacity, suitable for long-distance bus networking and multi-node high-power equipment. DVN24 thin cable has smaller outer diameter to save wiring space, ideal for short-distance and compact internal equipment wiring.
2.Q：DeviceNet 总线电缆双层屏蔽结构有什么作用？
A：内层铝箔屏蔽隔绝高频电磁干扰，外层镀锡铜编织网抵御低频电机干扰，双重屏蔽避免总线差分信号受干扰，防止通讯掉线、设备节点异常报错。
Q: What is the function of the double shielding structure of DeviceNet bus cable?
A: The inner aluminum foil shielding isolates high-frequency electromagnetic interference, and the outer tinned copper braided mesh resists low-frequency motor interference. Double shielding prevents bus differential signals from being disturbed, avoiding communication disconnection and abnormal error reporting of equipment nodes.
3.Q：这款总线电缆可以用于拖链往复移动布线吗？
A：标准款适合设备固定布线；如需长期拖链往复弯折，可定制高柔加强款 DeviceNet 电缆，提升耐弯折寿命。
Q: Can this bus cable be used for reciprocating mobile wiring inside drag chains?
A: The standard version is suitable for fixed equipment wiring. If long-term reciprocating bending inside drag chains is required, customized reinforced high-flex DeviceNet cables are available to extend bending resistance service life.
4.Q：线缆支持加工两端成品线束吗？
A：支持，可按需裁切指定长度，两端压接 DeviceNet 专用端子、M12 航空插头，无需客户二次加工，收到即可直接接线使用。
Q: Does the cable support finished wire harness processing on both ends?
A: Yes, custom cutting to specified lengths is available, with DeviceNet special terminals and M12 aviation plugs crimped on both ends. No secondary processing is needed for customers, ready for wiring upon receipt.
5.Q：现货与定制成品线束的发货周期分别多久？
A：整卷 DVN18、DVN24 标准线缆现货当天或次日发货；分裁短线、两端压接端子 / 接头的定制成品线束交期 3-7 个工作日。
Q: What are the delivery lead times for stock cables and customized finished wire harnesses respectively?
A: Standard full reels of DVN18 and DVN24 cables can be shipped same day or next day. Custom finished harnesses including cut short cables and cables with crimped terminals/connectors take 3-7 working days.
