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: The B-coding adopts a unique keyway positioning system, achieving incompatibility with A/C/D/X and other codings through a physical foolproof design, which effectively prevents the risk of incorrect insertion when connecting fieldbus devices.
☑ Two-Stage Sealing Design: Metal threads provide mechanical locking, and silicone rubber seals achieve IP67/68 protection rating. 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 demand of transmitting 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 more than 500 times.
