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.
IP67Fully 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.
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-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.
