Emerson KJ4010X1-BL3 1.5m Coax Extender Cable for DeltaV SIS
Product Summary
The KJ4010X1-BL3 is a factory-tested 1.5-meter black coaxial extender cable. Engineers use this cable to connect DeltaV SIS field junction boxes to marshalling panels. This specific model ensures high-integrity signal transfer for critical safety applications. It provides a robust and shielded connection that reduces electrical noise interference. This cable is a genuine Emerson replacement part for seamless system integration.
Product Procurement & Buyer Guide
Procurement managers must match the exact part number for DeltaV SIS installations. The KJ4010X1-BL3 is a dedicated 1.5-meter black Coax Extender Cable. Using a non-specified cable can introduce signal degradation or system faults. This cable supports the high-reliability requirements of a Safety Instrumented System. It guarantees a secure fit with standard DeltaV SIS termination blocks.

Application engineers value the precise 1.5-meter length for cabinet organization. This fixed length prevents excess cable looping and reduces signal loss. The black jacket provides basic protection against industrial dust and abrasion. You must verify your system requires the `KJ4010X1-BL3` and not a longer variant. Always procure this cable directly from authorized Emerson distributors for authenticity.
The cable’s construction ensures impedance matching for coaxial data lines. This matching is critical for maintaining the integrity of safety logic solvers. A mismatched cable can cause signal reflections and false trips. The KJ4010X1-BL3 mitigates these risks with its precision manufacturing. This makes it a reliable component for your safety lifecycle management.
Installation & Deployment Guide
Begin installation by verifying the cable part number against your project bill of materials. The KJ4010X1-BL3 requires careful routing away from high-voltage power lines. This practice prevents electromagnetic interference from corrupting safety signals. Secure the cable using appropriate tie-wraps to avoid mechanical stress on connectors.

Connect the coaxial BNC-type connectors firmly until you feel a positive click. Do not use excessive force that could damage the connector barrel. Ensure the cable bend radius does not exceed the manufacturer’s specification. A tight bend can break the internal shielding and cause intermittent faults. Always label both ends of the cable for future troubleshooting clarity.
After physical connection, perform a continuity test on the center conductor. Check the shield for a solid ground connection at both endpoints. The KJ4010X1-BL3 should show zero resistance for a proper circuit. Any deviation indicates a damaged cable or a poor termination. Follow these steps to achieve a reliable and safe system startup.
