The M12 B code connector is a circular connector specially designed for industrial environments, mainly used in Profibus and some other fieldbus protocols.
☑Encoding Keyway Structure:The B encoding adopts a unique keyway positioning system. Through a physical error-proof design, it achieves incompatibility with encodings such as A/C/D/X, effectively preventing the risk of incorrect insertion when connecting fieldbus devices.
☑Two-Stage Sealing Design:Metal threads provide mechanical locking, and silicone rubber sealing rings achieve IP67/68 level 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, which is suitable for the needs of transmitting low-to-medium power signals.
☑Durability：High-quality brass or phosphor bronze terminals undergo solid gold plating, which provides excellent oxidation resistance and ensures a plug-and-unplug lifespan of over 500 cycles.
