Contact technology simplifies multi-pole connector assembly
Multi-pole connector assembly can be simplified, says Harting, with the expansion of its Han Multiplier range. The Multipliers help simplify the assembly of connectors where multiple contacts are carrying the same potential voltage.
Interlinked cabling in decentralised control cabinets 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. They are particularly useful, says the company, for connecting motor drives/inverter control wiring in either star or delta connection arrangements.
The Multipliers are simply pushed onto the appropriate equipotential contacts, reducing both labour and material costs and installation times.
There are several standard connector types within the company’s range that can accommodate these multipliers, including Han-Yellock – an IP67 compliant, 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 (for example, 3:2, 2:3) up to five-way, and loaded from the front mating side of the insert.
The company has 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. This insert will also fit into the company’s Han-Modular system.
The latest connector series of inserts with Multiplier functionality is the finger-push cage clamp termination Han ES Press range. Han ES Press can accommodate rear plug-in multipliers/jumpers from two- to 12-way versions.
