Belden 9538 is a premium, high-performance 24 AWG, 8-conductor shielded multi-conductor cable engineered specifically for computer interconnections, data transmission, EIA RS-232 serial configurations, and low-voltage control circuits. Utilizing Beldens proprietary Beldfoil aluminum-polyester shield, this cable delivers 100% shielding coverage to safeguard critical data pathways from electromagnetic interference (EMI) and radio frequency interference (RFI) in electronically noisy industrial or office environments.
Key Features of Belden 9538
-
100% Beldfoil Shielding: Features a patented aluminum foil-polyester tape shield applied with the foil side facing out. This provides complete structural isolation against high-frequency electrostatic noise, ensuring data integrity over extended runs.
-
Integrated Drain Wire: Equipped with a 24 AWG stranded tinned copper drain wire. This configuration allows installers to easily terminate and ground the shield at terminal blocks without needing to manually untwist or comb out a braided layer.
-
Premium Conductor Construction: Consists of 8 conductors made from high-conductivity, stranded (7 x 32) tinned copper. The tinned coating provides excellent corrosion resistance and enhances solderability at connection points.
-
Semi-Rigid PVC Insulation: The conductors are wrapped in a robust, semi-rigid PVC (SR-PVC) layer, balancing precise electrical insulation properties with high physical resistance to crushing and mechanical wear.
-
Flexible Chrome PVC Jacket: Enclosed in a sleek, industrial-grade chrome PVC outer jacket that is highly flame-retardant and offers smooth pulling characteristics through conduit, drop ceilings, or dense equipment racks.
Common Applications
-
EIA RS-232 Serial Data: The industry standard wire profile for establishing reliable multi-line serial communication links between computers, PLCs, and peripheral devices.
-
Computer Interconnects: Interfaced routing for instrumentation networks, legacy mainframe terminals, and control room data consoles.
-
Instrumentation & Control: Transmitting low-voltage analog signals or digital discrete I/O pulses from sensors, control panels, and automation arrays.
-
Low-Voltage Security Systems: Multi-zone alarm links, keypad interconnections, and access control panel wiring.

Technical Note: When routing Belden 9538 for RS-232 serial communications, please note that this is a non-twisted pair cable (conductors are layered in a concentric cabled formation). For standard low-speed serial data or shorter runs, this configuration works perfectly. However, for high-speed differential communication protocols requiring balanced linessuch as RS-422 or RS-485a twisted-pair cable structure (like Belden 9504) should be selected instead to mitigate cross-talk between adjacent signal legs.
CABLE TYPE: 24 AWG / 8-Conductor Shielded Computer Cable
