The M12 B code connector is a circular connector specially designed for industrial environments, mainly used in Profibus and some other fieldbus protocols.
☑ Coding Keyway Structure: Coding B adopts a unique keyway positioning system. It achieves physical error-proofing design to ensure incompatibility with other codings such as A, C, D, and X, effectively preventing misplugging risks when connecting fieldbus devices.
☑ Rear Panel Mounting: Installation is performed from the back of the device panel, and it is fixed on the panel via threads.
☑ Board-Mounted Type: Directly soldered onto the Printed Circuit Board (PCB), this type ensures a more stable electrical connection between the connector and the PCB. It also simplifies the installation and maintenance processes.
☑ Dual-Stage Sealing Design: Metal threads provide mechanical locking, and silicone rubber sealing rings achieve IP67/IP68 protection. It can withstand an ambient temperature range of -40℃ to +85℃ and a vibration acceleration of 10G.
☑ Signal Transmission Characteristics: Supports fieldbus protocols such as PROFIBUS DP/PA and INTERBUS.
☑ Voltage and Current: Supports a rated voltage of 250V and a maximum carrying current of up to 4A, suitable for the transmission of low-to-medium power signals.
☑ Durability: High-quality brass or phosphor bronze terminals undergo solid gold plating, featuring strong oxidation resistance and ensuring a mating cycle life of over 500 times.
