The CM01-type protective T-bus connector is a connector with waterproof and dustproof function, which can be used outdoors. It has flexible configuration, allowing for the actual needs of 1-4 output ports. It uses waterproof terminals and locking cables imported from abroad, and has a high-quality built-in connector for easy wiring. It has a protection grade of IP65 and supports power supply functions, making it easy to set up large-scale field systems. It has anti-jamming capability and can be used for four-core shielded bus. It is made of high-quality engineering plastic, which is durable. It can be used with a power indicator as a product overview. CM01 is a practical application of engineering, responding to the needs of actual project development for connecting field bus cables and power modules for site acquisition and communication media services. Depending on the different needs of field installation, the T-extension-side bus connector has extension exports ranging from 0-4. The specific choice of the scene needs to be connected according to the temperature and the number of acquisition modules. When connected with the export extension 0, it is used as a junction box termination resistor. T-Bus connector can be used for bus connection of RS485 bus, CAN (CanOpen) bus, HART bus, Foundation Fieldbus bus, Profibus bus, LonWorks bus and other bus systems. The standard T-connector has w
The Sonbest CM01 protective T‑bus connector is a waterproof, dust‑proof field bus interface designed for outdoor use. It supports RS485, CAN (CanOpen), HART, Foundation Fieldbus, Profibus, LonWorks and other bus systems, and provides IP65 protection.
