Harting is introducing a new range of housing components which allow the company’s Han 3A size connectors to be produced with larger diameters, enabling them to be used with cables up to 25 per cent wider. As a result, customers will be able to use contact inserts with higher rated current and bigger cross-sections – such as the Han Q series.
The new housing components feature a narrow external geometry overall, terminating in the cable holding area. The housings are fully compatible with all the existing contact inserts in the series, and also meet the requirements of protection classes IP65/67.
The new Han 3A hood is available in a plastic version with a bigger M25 thread, allowing alternative types of mounting including direct mounting on control cabinets.
For the metal versions of the housings, coupling hoods are also available in the M25 option alongside the existing sleeve housings. As with the plastic housings, this allows the use of flying connections in addition to alternative types of mounting – for retrofits, for example. Other versions, such as the EMV electrically conductive unit and the M type for stricter corrosion requirements, are also available.
With the availability of metal or plastic HARTING M25 screwed cable glands, HARTING can now supply the complete range of screw fittings for all customer applications over the cable clamp range from 9 to 18mm.
