The AKB161-M100 is a specialized long-distance communication cable designed for Yokogawa industrial automation networks. Engineered for RS-422 and RS-485 serial communications, it provides a robust and reliable link between Alarm (ALM) side units and peripheral devices. The cable features a hybrid terminal design with M4 screws at the source end and M3 screws at the destination end, ensuring secure connections to industrial barrier strips. With a maximum factory length of 100 meters, the AKB161-M100 is ideal for extensive plant layouts requiring long serial bus runs.

Technical Specifications

Industrial Application Scenarios

The AKB161-M100 is widely used in CENTUM VP and STARDOM systems for:

• Connecting field control units to remote alarm panels

• Linking third-party PLCs or power monitors

• Bridging long distances between marshaling cabinets or from central control rooms to field equipment

• Preventing wiring errors with M4-to-M3 terminal differentiation

Its 100-meter reach makes it suitable for large-scale plant layouts while maintaining signal integrity over long runs.

Technical FAQs

1. Can this cable be cut into shorter lengths?
The cable can physically be cut, but factory-prepared M4/M3 terminal lugs would need to be re-crimped to maintain proper connectivity.

2. Is this cable suitable for Vnet/IP communication?
No. AKB161-M100 is for RS-422/RS-485 serial links only. Vnet/IP requires Cat5e or Cat6 Ethernet cabling.

3. What does "M100" signify?
It refers to the 100-meter cable length. It is not an environmental or G3 rating. For corrosive or harsh conditions, conduit or G3-rated alternatives should be used.
