Yokogawa KS1*A Signal Cables
Configured for signal transmission and data communication in distributed control systems, the Yokogawa KS1*A-01 (KS1*A Signal Cable) provides direct physical and electrical execution.
Suffix Breakdown & Model Matrix
The KS1A series utilizes specific length suffix configurations to define overall physical reach. The base model KS1A integrates a 40-pin to 40-pin interface structure. Available length options span standard deployment metrics from 1 meter up to 20 meters (-01, -02, -03, -04, -08, and -20).

Channel-to-Channel Isolation and Loop Performance
The 20-pair shielded cable design maintains signal integrity across interconnected DCS nodes by minimizing electromagnetic coupling and common-mode noise across low-level analog and digital signal channels. The internal conductor layout paired with an effective overall outer shield suppresses crosstalk and external interference in high-density industrial spaces, ensuring steady voltage and current loop transmission without distortion.
Frequently Asked Questions
Q: Can the KS1*A cable assembly be field-terminated or shortened manually? A: Field-termination of the factory-molded 40-pin connectors is not recommended due to the high density of the 20-pair conductors and specialized crimping tooling required to preserve shielding integrity.
Q: How should the cable shield be grounded to prevent ground loops? A: Terminate the shield drain wire to the designated functional earth ground terminal at the control cabinet side only, avoiding dual-end grounding to prevent circulating ground currents.
Field Installation Guidelines
Ensure system power is fully isolated before plugging or unplugging the 40-pin connectors to prevent arc faults or logic errors. Route the 20-pair shielded cable away from high-voltage AC power lines and variable frequency drive outputs. Observe proper mechanical strain relief near the connector backshells, ensuring bending radii do not exceed standard multi-conductor cabling thresholds during installation.
