Single-cable solutions with hybrid connectors (OCT – One Cable Technology) are becoming increasingly important in automation and robotics. They transmit power, signals and Ethernet in a single connection. This saves assembly time, space and money.

HUMMEL AG’s connectors are characterized by their absolute suitability for industrial applications. Metal housings protect the impact-sensitive contact inserts safely and reliably. The various housings, inserts and contacts can be combined and thus offer a large number of variants.

Hybrid connectors combine various electrical functions in one unit. They transmit power, signals (analog) and data/Ethernet (digital).

Advantages:

  • One connector instead of 2 or 3 (=>at least halving)
  • Reduced space requirement
  • Shorter processing time for connector assembly
  • Reduced costs
  • Less weight on the end device (e.g. motor)
  • Option: Several cables can also be brought together in one connector. (Multi)

Features of HUMMEL circular connectors:

  • Robust design
  • Mechanical protection of the contact inserts
  • No protruding plastic inserts
  • Better impact protection
  • Good processability
  • Time saving in connector assembly
  • Potential separated shields for Ethernet
  • Universal approvals
  • Modular concept: many variants in design and application
  • Daisy Chain: Cascadeable cabling through interchangeable inserts for the M16 and M23 series
  • INOX versions available (as screw Version)

Advantages:

  • One cable instead of two or three (=> at least halving)
  • Reduced space requirement
  • Lower weight (especially important in energy chains)
  • Less cabling effort, fewer wiring paths
  • Reduced costs for assembly and maintenance

DC-Industrie is a research project of the German Electrical and Electronic Manufacturers’ Association (ZVEI), which deals with DC voltage networks in industrial production. The aim is to bring more energy efficiency and energy flexibility into industrial production and thus implement the energy turnaround.

The characteristics of DC industry:

  • Direct voltage networks with central conversion
  • Energy-saving alternative for drives in production
  • Better integration of renewable energies (photovoltaics generates direct current, which must be converted before it can be fed into the grid)
  • DC mains with central converter replaces many decentralized frequency converters.
  • Higher efficiency of direct current networks. (Conversion from DC to AC and then back on site in power supplies or frequency converters of AC and DC reduces efficiency)
