Join Binder to explore the amazing versatility of M12 interconnects which are found in applications ranging from sensor networks to industrial drives, both indoor and out
Originally focused on vehicle engineering, M12 has become a robust, reliable, compact and high-performance interface in automation technology, for new and modernised infrastructure. The more IIoT prevails in modern factory and process plants, the greater the number of networking-capable automation components and interfaces.
Depending on coding and design, M12 connectors can transmit signals, data and power between field devices such as sensors, controllers, drives and nodes. On one hand, they can handle high data rates on Ethernet networks. On the other, they can supply drives with high power. To make best use of available space, data and electrical power can be transmitted via one connector.
A-coding (sensors, DC power) is available with three, four, five, eight and 12 pins. B (Profibus), D (100 Mbit Ethernet) and X (10 Gbit Ethernet) codings with four and eight pins, respectively, suit data transmission at different rates.
For power, such as AC drives and frequency converters, S and K (up to 630VAC, 16A) and DC drives or LED lighting, T and L (up to 63VDC, 16A) apply.
All M12 connectors provide minimum IP67 protection. Special variants in IP68 and IP69K suit hygienically demanding applications. Depending on the design, M12 connectors are intended for different applications. Versions with special termination such as crimping or wire clamp technology suit vibrating applications. Others suit outdoor use being resistant to UV radiation. Metal, plastic or stainless steel housings are available.
