Number of contacts
This indicates the number of contacts the connector has.
Lock
The locking system describes how the pin and socket elements are joined.
  • 1/2 UNF 1/2″ UNF is an American unit of measure. In the case of connectors, it refers to the size of the locking thread.
  • 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.
  • 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.
Version
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.
EMC
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.

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.
Coding
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-US Originally from the USA, this coding is standardised according to DIN EN 61076-2-101 with 3 to 6 contacts. It includes a leading PE contact. It is used in AC sensors, which were very widespread in the USA.
Termination
The termination type determines how cables, single wires or PCBs can be joined with the connector.
  • moulded on cable Single wires are assembled and the cable joined with the connector by means of plastics injection moulding.
  • screw clamp The wires in a cable are pressed in the contact element radially by means of a screw, establishing the electrical contact.
  • solder The contact and the individual wires of a cable are connected using solder.

The 815/866 series are connectors with US - C coding and M12 or 1/2 inch UNF screw locking in protection class IP67/IP68. The connectors are available as straight and angled cable connectors with screw terminals or with moulded cable in 2 m and 5 m lengths as standard. 2+PE, 3, 4 or 5 contacts are possible.
