Prefabricated SAI (Sensor/Actuator/Interface) and IE (Industrial Ethernet)‑cables

Circular and rectangular connectors are standard in machinery and plant engineering as well as robotics. They allow fast and error-free installation even in difficult plant conditions, far removed from an ergonomic, well organised workplace. In addition to the robust M12 circular connectors, there are now M8 and M5 versions available too – they are an interesting alternative to compact and weight-sensitive applications. Weidmüller offers prefabricated cables made from PUR, PVC and LSZH in lengths of 1, 3, 5 and 10 m. Transparent labelling sleeves and a wide range of colours ensure a clearer overview during installation. The cables are available with M8, M12, M16, 7/8", M23 and RJ45 plug-in connectors in different design types and codings. 360° shielding, vibration resistance and protection ranging from IP65 to IP69 guarantee fault-free operation. Alternatively, users can also arrange to have customised variants produced, whether identical on both sides, with different plugs or with open cable ends. Weidmüller offers specific solutions with demand-oriented cable lengths, plugs, markings or colours from a batch size of one. Finally, customised cables can also be compiled in direct contact with Weidmüller specialists – the third ordering option.

PLC system cabling

Simultaneously save space and avoid installation errors, since the control system universal cabling reduces connection points and ensures greater efficiency and safety in panel building. With its compact interface units, Weidmüller offers a complete range of prefabricated cables for connecting to the most important control systems on the market: Siemens, ABB, Honeywell, Mitsubishi and many more.
The cable used is multipolar with a cross section of 0.25 mm². This is also shielded from the cables for analogue signals. Each individual cable is identified using the colour coding defined in DIN 47100. The original plug-in connector from the manufacturer is used for the PLC connection. Three different connector types are used as interface connectors. Besides standard connectors for digital signals, there are also extremely stable RSV plug-in connectors available for high voltages up to 230 V or SUB-D connectors for analogue signals.

Custom cable assemblies

The planning, procurement and assembly of custom cables often leads to high costs. The connectivity professionals offer support with this: Weidmüller develops continuous connection solutions from IP20 to IP6x – reliable, tested and all from a single source. Any combinations are possible, even open on one or two sides. The customer is free to choose. ▪ ds
