Shielding minimizes electromagnetic interference (EMI) in industrial environments. The M4-to-M3 asymmetric terminal configuration guarantees correct physical alignment with Yokogawa modules and peripheral devices. This cable can operate in conjunction with 4-20 mA HART loops or FOUNDATION Fieldbus\/ProfibusPA-connected networks when integrated into Yokogawa DCS and SIS architectures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eQ: Can the AKB161-M100 be used beyond 100 m?\u003cbr\u003eA: Cable length is limited to 100 m per Yokogawa specification.
