Introduction
HUMMEL circular connectors are used in many industrial applications. The product range covers sizes M8 to M40. Whether power or signal connectors, Industrial Ethernet or customer-specific special applications HUMMEL offers the right solution for every requirement. Quick release fastener variants, angle, coupling and appliance plugs for the most varied installation situations round off the respective product families; they are also available as INOX versions.

Hybrid
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)
