Creating a clean connection

02 March 2020

The latest addition to the Han connector portfolio is the Han F+B, a range of connectors which have been specially designed for the requirements of the food processing, bottling and packaging industries. Within these sectors, hygiene and safety are key considerations, meaning machines and equipment must be both easy to clean and designed so dirt pockets and bacteria cannot accumulate. 

The Han F+B has been developed as a suitable product for the food zone and primarily the splash zone – Zones 1 and 2 defined in the EN 1672-2 standard. Firstly, all hoods, housings and seals are IP69K rated, so the connections are fully protected and resistant to the water jets used to clean equipment. They also have large nooks and surfaces in accordance with the guidelines of the European Hygienic Engineering & Design Group (EHEDG), which allows cleaning and disinfecting agents to flow unhindered. For secure identification and easy traceability, the connectors are blue, although a black version is available.

The range is Ecolab approved, which means it is resistant to aggressive cleaning agents used in the food and splash zones. As the housings are constructed from polypropylene, they conform to the directives of FDA 21. All surfaces also have a smooth finish, which prevents impurities and bacteria from accumulating, whilst the portfolio can function in a wide temperature range from -40 to +125°C. Cable glands available include variants made of PA plastic in combination with blue silicone sealing rings, which achieve the highest degree of protection against the penetration of dust and water.

As well as hygiene and safety concerns, HARTING has also considered the impact of machine downtimes, designing in features which keep disruptions on the production line down to a minimum. The ability to quickly attach and detach connectors, for example, is vital to help minimise production downtimes.

With the Han F+B, operators do not need to open any cable glands on the control cabinet in order to decouple field devices, eliminating the complex disconnecting and reconfiguring of fixed wiring. This solution also allows for faster replacement of defective components and a more efficient configuration when changing components.
