The combination of an aluminum foil wrap and a high-density braided copper shield minimizes high-frequency electromagnetic interference (EMI) and radio frequency interference (RFI) across extended 100 m paths. This physical shielding structure prevents electrical cross-talk between adjacent communication lines and mitigates ground potential differentials, which ensures stable data rates when deployed alongside 4-20 mA HART loop protocols and FOUNDATION Fieldbus segments. The asymmetric M4-to-M3 physical termination ensures correct directional installation between host I\/O nests and peripheral terminal boards.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the AKB161-M100 assembly support online hot-swapping or physical extraction while the ALM module communication loop is active?\u003c\/p\u003e\n\u003cp\u003eA: Yes, because the hardware is a passive electrical component with no integrated active semiconductors, it can be physically unbolted and removed from the terminal blocks without causing electrical damage to the host system. However, disconnecting the cable will instantly interrupt the Modbus or subsystem serial loop, resulting in a communication failure alarm at the DCS or SIS engineering station.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum physical tensile load capacity and minimum bend radius allowed for this 100 m shielded cable assembly during installation?\u003c\/p\u003e\n\u003cp\u003eA: The passive cable structure must not be subjected to sharp bends. During installation, engineers must adhere to standard industrial cabling practices by maintaining a minimum bend radius of at least 10 times the outer cable diameter. Avoid mechanical strain or high vertical pulling forces during deployment through cable trays to prevent degradation of the twisted-pair geometric integrity and shielding layer continuity.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical Separation:\u003c\/strong\u003e Route the communication assembly through dedicated low-voltage instrument trays. Maintain a minimum physical clearance of 300 mm from high-power AC conductors, variable frequency drive output lines, and inductive motor control circuits to prevent electromagnetic noise coupling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Grounding Protocol:\u003c\/strong\u003e Terminate the cable shield braid at a single reference point only. Connect the shield to the dedicated functional instrument ground terminal on the ALM host side. Do not connect the shield at the subsystem terminal end to prevent the formation of ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Torque Values:\u003c\/strong\u003e Secure the asymmetric connectors using calibrated tools. Tighten the M4 screw terminals on the ALM interface to a target torque rating of 1.2 N m. Tighten the M3 screw terminals on the subsystem side to a maximum torque rating of 0.6 N m to avoid stripping the terminal threads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwisted-Pair Integrity:\u003c\/strong\u003e When stripping the outer jacket for terminal connection, minimize the untwisting of the internal pairs. Keep the untwisted segment below 15 mm from the screw termination point to maintain the common-mode rejection characteristics of the RS-422\/RS-485 physical layer.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43683818897498,"sku":"AKB161-M100","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/631..jpg?v=1784599205","url":"https:\/\/www.spareoil.com\/products\/signal-cable-assembly-yokogawa-akb161-m100-centum-vp","provider":"SpareOil Automation","version":"1.0","type":"link"}
