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.
IP20Protects against contact with fingers and against foreign bodies of Ø > 12.5 mm. Does not protect against water.
IP40Protects 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.
IP67Fully 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 accessoriesFully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).
IP68Fully 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.
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.
Automation TechnologyAdvancing 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-BThis 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-DThis 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-KThe 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-LThe 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-SThe 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-TThe 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-USOriginally 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-XThis 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.
cableConnectors pre-assembled with a cable, for installation in housings.
dip-solderThe special form of the contacts enables a through-connection on a PCB and automated wave soldering.
moulded on cableSingle wires are assembled and the cable joined with the connector by means of plastics injection moulding.
pluggableAdapters or distributors that are joined with a connector on each side. The version and locking system may vary for the different terminations.
reflow solderingSoldering 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 clampThe wires in a cable are pressed in the contact element radially by means of a screw, establishing the electrical contact.
single wiresConnectors with contacts attached to individual wires ex factory. These can then be connected individually.
solderThe contact and the individual wires of a cable are connected using solder.
wire clampThe connection of the individual wires of a cable with the contacts is established by spring power, allowing quick assembly.
