Han-Modular® - Your benefits at a glance

Hinged frame offers more installation advantages and cost savings

HARTING has complemented the well-known Han-Modular® building block system with the addition of the new "hinged frame plus". Among others, the “plus” for the proven hinged frame comes in the form of an additional stainless steel spring that holds the frame together in the open and closed positions, as well as other details that have been optimised. Particular time and cost advantages result from the fact that assembling the connector modules is easier and more efficient.

Compressed air transmission in the connector

The Han® Pneumatic Module enables prepared compressed air to be transmitted via connectors, which is required for e.g. drives. The blue colouring of the pneumatic module makes it stand out from electrical modules. Depending on requirements, the male and female contacts can be used for various pneumatic hose diameters (∅ = 1.6 to 6mm). The module can also be combined with all other modules in the Han Modular® series. This means that in addition to electric power and electrical signals, fibre optic signals and gaseous media can also be transmitted in pluggable mode. The module is available in variants with two (for hose ∅ = 6 mm) or three plug slots (for hoses with ∅ = 1.6 to 4mm). The female contacts are available with or without shut-off function. In the shut-off variant a spring-loaded valve closes over an O-ring when the connector is opened. This prevents compressed air from escaping. When plugged in, the male contact presses against the valve and keeps the contact open

Han Modular® for high mating cycles

Industrial facilities increasingly feature modular designs. More and more mobile equipment is being used in manufacturing, and swap-outs are being done more frequently and as quickly as possible. This also means that more connectors are required which are designed for a high number of mating cycles. The HARTING Han Modular® “High Mating Cycles” (HMC) hinged frame allows the integration of contacts designed for especially high mating cycles (10,000 insertions/removals) in inserts from the proven Han Modular® series. Use of the Han Modular® HMC hinged frame means Han® Modular modules can be integrated into a HMC housing – and are consequently equipped for over 10,000 mating cycles. The HMC hinged frame differs from conventional hinged frames particularly with regard to the PE contact. The contact is specially coated in the HMC hinged frame and is attached to the latter using a special process.

PE module does away with special cables for power connectors

HARTING has extended the Han Modular® series with the introduction of a module for the pluggable connection of large PE cross-sections (10-35 mm²). The hinged frame of the Han Modular® series already features two integrated PE connections for the 0.5-10mm² cross-section range. Cross-sections of 10-35 mm² can now be realized using the new pluggable PE module. Special cables with reduced PE are no longer necessary. The PE module is simply mounted in the articulated frame, creating a secure, electrically conductive connection from the PE contact to the hinged frame and the housing. The PE protective earth connection is pre-leading and complies with standard IEC 61984.

Modular connector for Ethernet networks

Networking and digitisation of manufacturing processes has meant an increase in the proportion of Ethernet components at the field level. To meet this trend, HARTING developed the Han Modular® Switch US4. The US4 enables components such as high-resolution cameras used for quality assurance to be e.g. integrated into the network of a production facility with little effort. The Ethernet Switch US4 is suitable for industrial applications and supports Ethernet (10 Mbit/s), Fast Ethernet (100 Mbit/s) and Gigabit Ethernet (1000 Mbit/s). Up to 4 devices can be connected via RJ45 ports. The US4 Switch is Plug&Play compatible, and integrated LEDs provide quick and easy power and network diagnostics. HARTING’s strategy towards smarter connectors goes further: an ID module provides memory space for the connector. Other solutions emerging on the horizon are integrated sensors and wireless modules in the modular connector.
