8-pole connectors for heavy-duty applications

In industrial and automation systems, where power and signal connections “coexist” for the management of motors, machines and control units, electrical connection solutions are required with polarities that confirm the functionality of the system.

Techno responds to this need by launching the 8-pole version of the TH405 and TH406 families , the latest evolution of a range of plug & socket connectors that has found wide use in the lighting sector in critical environments.

Electrical and mechanical characteristics

Available in a cabled and panel mount versions, the new 8-pole TH405 and TH406 offer maximum IP68 protection from water and dust The bayonet locking system with safety lock between the socket connector and the plug connector means that can only be opened with a tool. The connectors are designed to meet the mechanical resistance to impact of IK08.

The connector components are modular: the connector case accepts variable polarity connectors of 2, 3, 4, 5, 6 and 8 poles, ensuring maximum interchangeability and versatility during installation.

The TH405 and TH406 connectors are rated up to 25A and are suitable for applications up to 400V AC. The 8-pole connector, on the other hand, allows current up to 10A/400V.

Practical and compact

These connectors can be wired with 8-pole cables up to 13.5 mm of external diameter and with conductors with a maximum section of 1mm². The screw connectivity makes them easy to install in the field. Compared to many solutions on the market, such as IEC309 industrial sockets, the TH405 and TH406 connectors also stand out for their limited overall dimensions : they can be placed inside machinery and control systems.

They are completed by the TH631 power distributors, supplied pre-wired and with socket-plug connectors, suitable for the rapid distribution of power or signal (available on request).

Materials and performance

The body of these connectors is made of PA6.6 technopolymers, with intrinsic characteristics of very high resistance to UV rays (f1 index, according to the UL746C standard), extreme temperatures and corrosion from external agents.

Their compactness is made possible by the high self-extinguishing capacity (V0 and 5VA index) of the aforementioned material: the greater the capacity to interrupt combustion, the smaller the thicknesses permitted, without any compromise to the technical-application characteristics of the product.

The 3- and 5-pole versions are UL and CSA approved for use in the USA and Canada.

For severe operating conditions

With the TH405 and TH406 8-pole plug-socket connectors, Techno offers a solution for “heavy-duty” applications: lighting systems in harsh operating conditions, industrial areas and any application located in adverse climatic conditions, characterised by high humidity and extreme temperatures, as well as mechanical stress.

Accessories

To prevent installation problems, Techno has provided a complete range of accessories.

• Additional cable fixing systems to the cable gland for greater tensile strength

• Blanking caps for connectors left temporarily disconnected

• Quick installation key for closing cable glands and quickly fixing the cable

Techno contributed to the lighting of Rome

The TH405 connectors were selected by the multi-service company Acea of Rome, to power LED street lamps, replacing the same number of traditional lamps installed on the streets of the Capital. Learn more here
