M16 circular connector
M16 circular connectors for industry
The M16 circular connector offers a high performance for different industry applications and above all is a good choice for installation because of its compact design. These are standard applications in mechanical engineering, for sensors and switches in industrial electronics and many other branches where metric circular connectors reliable connect actuators and sensors together.
The M16 connectors task is to securely transfer power, signals and data. The number 16 defines the diameter of the thread size in millimetres. The range of M16 connectors includes a selection that differs in terms of design, shape and other technical specifications. In addition, the conditions of the installation and environmental factors must be taken into account when selecting.

Different types of M16 connectors Hummel
The product range of various Hummel M16 connector types includes different types, in order to individually meet the requirements of the industry applications. The M16 connectors differ in terms of design and shape in order to achieve the greatest possible flexibility.
Depending on the requirement, pin and M16 socket are available straight or angled, which are suitable both for front-wall and rear-wall installation and provide tension relief. The connection technology comprises a solder connection that is used specifically for signal connectors and PCB connectors. The M16 cable connector is available with rated voltages of 60V and 250V at a rated current of either 3A, 4A, 5A or 7A. The M15 DIN connector withstands temperatures of -40° C to 95° C and with more than 500 mating cycles has a long service life, some versions have a shield function. Corresponding to protection class IP67, the M16 motor connector offers complete protection against dust and offers temporary protection if immersed in water.
M16 connectors coding
The pinout of different cables can be controlled via the M16 connector pinout. The M16 connector pinout corresponds here to the standard. Misconnection can be prevented by the coded connectors. The desired power, data or signal transmissions by the cables are defined individually. The M16 connector is available in various pin numbers in order to cover the various application requirements. The M12 connector x-coded at Ethernet interfaces manages data communication of up to 10 GBit/s.
Available pin numbers for M16 connectors
Different pin numbers facilitate the individual control of information, data and signals – in a compact cable that also ensures secure transmission in a small space. In addition, the various requirements for data and signal transmission are covered. The connector is available with the following common pin numbers:
- M16 connectors 3-pin
- M16 connector 5-pin
- M16 connector 8-pin
