Number of contacts
This indicates the number of contacts the connector has.
The locking system describes how the pin and socket elements are joined.
  • M12 The connectors can be screwed together to secure the connection. M stands for metric thread and the number stands for the external diameter.
Degree of protection
The degrees of protection according to IEC60529 apply to various articles and provide information on protection against the intrusion of water and solids such as dust.
  • IP20 Protects against contact with fingers and against foreign bodies of Ø > 12.5 mm. Does not protect against water.
  • IP67 Fully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).
  • IP68 Fully protects against touch and against the intrusion of dust. Protects against water intrusion in sustained submersion (depth: 2 m; duration: 24 hours), requirements specification by agreement between producer and user.
The choice of version allows the definition of certain technical specifications – for example the type of cable outlet or the size.
Installation type
Connectors are differentiated by installation type: those that are mounted in a device housing (panel mount) and those that are attached to cables.
Electromagnetic compatibility (EMC) means that a connector is shielded or shieldable. This is required when it is necessary to protect the signals or data conducted by the connector, as well as to protect external devices, from disturbance due to electromagnetic effects.
Product segment
binder areas of application or type of connector.
  • Automation Technology Advancing digitisation and current manufacturing technologies make possible ever smaller and more high-performance elements in the areas of sensor technology and networking. Here, sensor technology means the detection of physical values and their conversion into electric values. These electric values are converted into a digital signal that can be transmitted by means of bus communication to other bus devices. This will make automated production more modular and flexible in the future, with a preference for standardised connectors like the models M8 and M12. The worldwide availability of the connectors and their adaptation to a broad range of applications have already led to numerous versions, e.g. codings.
To avoid mismating, the connector elements – the pin and socket – must be brought into form-fitting alignment with one another (coding) before being locked.
  • M12-D This coding was developed as a 4-contact, shieldable connector and standardised in accordance with DIN EN 61076-2-101 as one of the first for fieldbus wiring – e.g. PROFINET. It is used for data transmission at rates of up to 100 Mbit/s. Data transmission is becoming ever more prevalent and thus increasingly important.
  • M12-X This coding was specially developed as an 8-contact, shieldable connector for data cabling applications with high data quantities and data transmission rates – e.g. PROFINET. Standardised according to DIN EN 61076-2-109, the connectors feature a comparatively high degree of protection and are used for data transmission at rates of up to 10 Gbit/s. Global data transmission is becoming increasingly prevalent and thus increasingly important.
The termination type determines how cables, single wires or PCBs can be joined with the connector.
  • cable Connectors pre-assembled with a cable, for installation in housings.
  • dip-solder The special form of the contacts enables a through-connection on a PCB and automated wave soldering.
  • moulded on cable Single wires are assembled and the cable joined with the connector by means of plastics injection moulding.
  • pluggable Adapters or distributors that are joined with a connector on each side. The version and locking system may vary for the different terminations.
  • reflow soldering Soldering process in which the entire connector is exposed to the soldering temperature in a soldering furnace. Special plastics allow brief resistance to temperatures of > 260°C. This termination enables, especially, contact on a PCB.
  • screw clamp The wires in a cable are pressed in the contact element radially by means of a screw, establishing the electrical contact.
  • single wires Connectors with contacts attached to individual wires ex factory. These can then be connected individually.

M12 connectors with D and X coding of the 825/876 series for high-performance applications such as PROFINET and Ethernet have screw/cut terminal connections. Cable connectors are also available with moulded cable, flange connectors have solder and dip solder connections. The connectors are excellently shielded and comply with protection class IP67.
