The KJ4002X1-BF3 bottom extender cable assembly extends backplane connections below a DeltaV carrier. Emerson builds this assembly for cabinets that need extra vertical wiring space. It carries power and communication signals between carrier sections without adding new modules.
Cable Length and Connector Interface
The assembly measures 600 mm from end to end, which gives crews room to route cables around cabinet hardware. Two 40-pin connectors terminate each end and mate with the carrier backplane ports. The shielded cable jacket blocks electromagnetic interference from adjacent power lines. Moreover, molded strain reliefs protect the conductors at both connector joints.
Physical Dimensions and Construction Details
The assembly weighs approximately 0.5 kg, so it hangs without extra support brackets. The cable jacket uses flame-retardant PVC and tolerates temperatures from -20 °C to 80 °C. Each connector housing carries keying slots that prevent reversed mating. A braided shield ties to the connector shell and drains noise to chassis ground.

Installation and Routing Notes
Technicians connect the KJ4002X1-BF3 between the lower carrier port and the extender frame. The keyed connectors seat fully with light hand pressure, so no tools are needed. Crews should route the cable away from drive wiring and transformers. Therefore, signal integrity stays high even in densely packed cabinets.
Why This Assembly Fits DeltaV Cabinet Layouts
Integrators choose the KJ4002X1-BF3 for its 600 mm reach and shielded construction. The extra length simplifies backplane routing when carriers stack in tall cabinets. Braided shielding keeps communication lines clean in electrically noisy plant rooms. This assembly serves marshalling builds in refineries, chemical plants, and power stations.
