HARTING announced the expansion of its Han ® Multiplier range. Han ® Multipliers
help simplify the assembly of connectors where multiple contacts are carrying the same
Interlinked cabling of decentralised control cabinets in a modern factory/
production line environment often creates situations where multiple contacts need the
same potential (e.g. Ground or 24V), for example when providing connections for
sensors, switches and Powerbus daisy chaining. In such cases, Han ® Multipliers allow
for the use of a single feeding line instead of multiple feeding lines of the same potential.
For example Han ® Multipliers are particularly useful for connecting motor drives/inverter
control wiring in either star or delta connection arrangements.
HARTING Han ® Multipliers, which are simply pushed onto the appropriate
equipotential contacts, can therefore significantly reduce both labour and material costs
and installation times by simplifying connections.
HARTING/037/2 HARTING Han ® Multipliers
There are several standard connector types within the HARTING range that can
accommodate these multipliers, including Han-Yellock ® – an IP67 compliant, smoothly
contoured design with single-handed push button mating that supports cable-trunking
drag-through installations. Inserts can be loaded from the front or rear side of a bulkhead
panel. Multipliers are available in various types, such as 3:2, 2:3 etc., up to 5 way size
and loaded from the front mating side of the insert.
HARTING has also recently developed a separate single 15 way Han-Yellock ®
Multiplier Block insert, based on its 16A rated Han E ® crimp contacts, which can also be
fitted with the full range of Han-Yellock ® Multipliers. The key feature of this particular
insert is that it will also fit into HARTING’s Han-Modular ® system concept.
As a result, HARTING’s multiplier concept can now be applied right across
HARTING’s multipole I/O connector range of die-cast aluminium IP65 compliant Han ® B
and compliant IP68 Han ® HPR high-strength construction hoods and housings, rugged
plastic Han-Eco ® series and can also be used inside switch cabinets, integrating with the
Han-Snap ® series.
The latest Han ® connector series of inserts that offer this Multiplier functionality is
the new finger-push cage clamp termination Han ® ES Press range. Han ® ES Press can
accommodate rear plug-in Multipliers/Jumpers from 2 to 12 way versions.
Howard Forryan, product marketing specialist at HARTING Limited, said; “These
Multipliers provide an example of how HARTING continues to develop new innovative
connector technology design solutions for our world renowned series of rugged Han ®
rectangular multipole connectors. HARTING also takes great care to ensure that these
advances also provide backwards compatibility, allowing upgrades and improvements to
be accommodated for minimum extra cost.”
