Integrated overall shielding suppresses electromagnetic interference (EMI), preserving signal fidelity for 4-20 mA HART loop protocol communications passing between I\/O modules and terminal interface units. High-spec insulation materials ensure stable conductor impedance and CJC signal accuracy across extended operating environments from -20 to 70 deg C.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What precautions should be taken regarding the bend radius when installing the KS1-20*B cable assembly?\u003c\/p\u003e\n\u003cp\u003eA: Maintain a minimum cable bend radius of 10 times the outer cable diameter during installation to prevent internal conductor stress and connector strain.\u003c\/p\u003e\n\u003cp\u003eQ: Is the KS1-20*B 40-pin cable suitable for outdoor direct burial applications?\u003c\/p\u003e\n\u003cp\u003eA: No, the cable assembly is specified for indoor, tray, or conduit mounting within control cabinets and must be protected from direct moisture and chemical exposure.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eConnect the 40-pin connectors at each end of the KS1-20*B cable directly to the designated I\/O module and terminal block interfaces, ensuring side locking clips engage fully to prevent accidental loosening under vibration. Route the 20 m cable length through dedicated low-voltage wiring ducts, maintaining a minimum 150 mm distance from high-power AC conductors. Ground the cable braid shield clamp firmly to the protective earth (PE) bus bar at the cabinet entry point using short ground straps. Ensure ambient operating conditions stay strictly within -20 to 70 deg C.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":48759121084606,"sku":"KS1-20*B","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-08-19_15-36-05_1200x1200_596cc499-2c01-4e00-942c-bd74a5b3c717.jpg?v=1787125665","url":"https:\/\/www.autooiltech.com\/products\/yokogawa-ks1-20-b-signal-cables","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
