Belden Alpha Essentials Communication & Control Series Control Cable, 305m Cable Length, 300V Voltage - 2421C SL001


This control cable provides screened, two-core connectivity for control and communication tasks in industrial installations. It combines tinned copper conductors with a flame-retardant outer sheath to perform in systems requiring moderate voltage handling and environmental resilience. The product is supplied on reels and intended for use where a Compact screened cable with reliable electrical characteristics is required.

Features & Benefits


• 16-strand tinned conductor gives flexible current-carrying capacity
• Screened construction reduces electrical interference for clearer signals
• Flame-retardant polyethylene jacket limits flame propagation during faults
• 300V rating supports standard control circuits and panel wiring
• Temperature range from -20°C to 75°C permits indoor and sheltered outdoor use

**Applications**


• Suitable for motor control wiring in automation cabinets
• Ideal for signal runs between sensors and controllers
• Used for interconnects in machine tool control systems
• Can be used for wiring in building management systems
• Suitable for factory-floor instrumentation and control panels

How is the cable shield implemented and terminated?


An aluminium/Mylar foil with a tinned copper drain wire provides shielding

the foil faces outward and the drain wire facilitates straightforward termination to earth.

What electrical performance can installers expect for impedance and capacitance?


Characteristic impedance is nominally 54 Ω with conductor-to-conductor capacitance around 31 pF/ft and ground capacitance about 56 pF/ft at 1 kHz for signal-integrity planning.

What mechanical limits apply during installation pulls and bending?


Maximum pull tension is 33 lb and the recommended bend radius is ten times the cable diameter to avoid conductor or jacket damage.

In what colours and packaging lengths is the cable available?


The outer jacket is supplied in slate and brown and can be provided on reels or boxed lengths including continuous 305 m, 152m and shorter spool options (equivalent to 1000 ft, 500 ft and shorter lengths).

Which approvals cover suitability for use in regulatory environments?


The cable carries CE marking and meets recognised North American standards with CSA and UL listings as applicable.
