Versatile connector solutions for the food and beverage industry
The newest addition to the Harting Han portfolio is the Han F+B, a range of connectors designed for the requirements of the food processing, bottling and packaging industries, says Brian Coyle, product manager at Harting UK

ithin these sectors, hygiene and safety are key considerations, meaning machines and equipment must be easy
to clean and designed so that dirt pockets and bacteria cannot accumulate, within the system. The EN 1672-2 standard defines three distinct
zones for food production, which differ in terms of contamination risks and the number of cleaning cycles required. Zone 1 is the food zone, where components come into direct contact with foodstuffs. Zone 2 is the splash zone, where components must be cleaned regularly using high pressure washing and chemicals to avoid contamination. Anything outside of these two zones is classed as a non-food zone, where the contamination risk is minimal. The Han F+B has been specifically developed as
a suitable product for the food zone and primarily the splash zone and there are several innovations which make it the ideal solution. 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. The connectors 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, meaning it is
resistant to the highly 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, and all surfaces also have a smooth finish, which prevents impurities and bacteria from accumulating. The entire portfolio can also function in a wide temperature range from -40 to +125° C. As well as hygiene and safety concerns, Harting
has also considered the impact of machine downtimes, designing in features which keep production line disruptions down to a minimum. In order to embrace flexible schedules and the
manufacturing of smaller batches, production lines must become more adaptable. As a result, the ability to quickly attach and detach connectors is vital if costly production downtimes are to be avoided. 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 complex disconnecting and reconfiguring of fixed wiring. This solution allows for faster replacement of defective components and a more efficient method of changing equipment, meaning
businesses in the food industry can shorten set-up times and reduce production stoppages. The Han F+B series has also been designed so
it can be plugged and unplugged easily, safely and quickly. Special fluting in the housing walls ensure that the installer’s hands do not slip off the connector, even in damp or humid conditions. A considerable additional advantage to
customers is that Harting can also supply Han F+B Hybrid Ethernet, signal, and power integrated cable assemblies. These ‘Plug & Play’ assemblies are 100% tested to guarantee high quality standards and are available in customised lengths. For outside the product and spray zones, Harting
offers a wide range of connectivity solutions. The connectors of the Han-INOX series have stainless steel housings and are particularly resistant to the chemical cleanings of the food industry. The interior, including the contacts, is safely protected against splashes of water to IP65 Harting have also developed the Han-Eco B, a
new series of hoods and housings available in a range of designs including bulkhead, surface- mount and cable-to-cable. They are manufactured from high-performance polyamide plastic, which offers IP65 protection and complies with standards IEC 61948 and EN 45545-2. In response to the miniaturisation trend across
industries and sectors, the Han 1A is designed for connecting tools and smaller machine modules such as heating and cooling units, fans, drives and vibration conveyors. Constructed from lightweight yet durable polyamide plastic, the Han 1A is extremely adaptable because it employs a modular system of inserts. This means it can integrate contacts for the delivery of data, signals, and power. To learn more about the Han F+B and download
