Lock The locking system describes how the pin and socket elements are joined. Lock
- 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.
- 7/8" 7/8″ 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.
- M18 The connectors can be screwed together to secure the connection. M stands for metric thread and the number stands for the external diameter.
- locking latch The locking system of the Ethernet connector RJ45 allows the easy plug-in and release of data connections. This is facilitated by the connector’s locking system with locking hook.
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. Degree of protection
- IP20 Protects against contact with fingers and against foreign bodies of Ø > 12.5 mm. Does not protect against water.
- IP40 Protects against contact with tools, wires and other similar objects of Ø > 1 mm and against the intrusion of foreign bodies of Ø > 1 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).
- IP67 with seal, see accessories 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.
- IP68/IP69K <u>IP68:</u> Fully protects against touch. Protects against the intrusion of dust. Protects against water intrusion in sustained immersion (depth: 2 m; duration: 24 hours), requirements specification by agreement between producer and user.<br/><br/><u>IP69K:</u> Fully protects against touch. Protects against the intrusion of dust. Protects against water intrusion under high pressure (8,000–10,000 kPa) from a jet or from steam-jet cleaning from any direction.
Version The choice of version allows the definition of certain technical specifications – for example the type of cable outlet or the size. Version
- Adapter Connecting element to each side of which a connector can be attached. This enables the realisation of, for example, control cabinet lead-throughs or a transition from the M8 to the M12 locking system.
- Connecting cable Connecting cable in various pin and socket versions.
- Connector female angled Connector (socket/female) with angled cable outlet.
- Connector female straight Connector (socket/female) with straight cable outlet. Here, the cable runs in mating direction.
- Connector male angled Connector (pin/male) with angled cable outlet.
- Connector male straight Connector (pin/male) with straight cable outlet. Here, the cable is in mating direction.
- Distributor In distributors, an input current or signal is distributed over multiple outlets according to a particular wiring logic. The locking system/termination for the input may differ from that for the outlet.
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. Installation type
- Cable mounting Connectors with cable already moulded or for self-assembly.
- Housing assembly Connectors that can be mounted to device housings. These can be fixed by means of a locking nut or be screwed in (requires a threaded hole).

- 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. Coding
- M12-B This coding was developed, standardised and used in accordance with DIN EN 61076-2-101 as one of the first for fieldbus wiring – e.g. PROFIBUS – with either 4 or 5 contacts. It originally included a PE contact which enabled its use for power supply. The norm has meanwhile been adapted and the PE contact removed.
- 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-K The M12 K-Coding is a power coding designed for voltages of up to 630 V AC. It allows the use of conductors of up to 2.5 mm².
- M12-L The M12 L-Coding is a power coding designed for currents of up to 16 A. It allows the use of conductors of up to 2.5 mm².
- M12-S The M12 S-Coding is a power coding designed for voltages of up to 630 V AC. It allows the use of conductors of up to 1.5 mm².
- M12-T The M12 T-Coding is a power coding designed for currents of up to 16 A. It allows the use of conductors of up to 1.5 mm².
- 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.
- 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.
Termination The termination type determines how cables, single wires or PCBs can be joined with the connector. Termination
- 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.
- solder The contact and the individual wires of a cable are connected using solder.
- wire clamp The connection of the individual wires of a cable with the contacts is established by spring power, allowing quick assembly.
