PC20-BY Partex PC20 Clip-on, chevron cable marker, 3.0–4.0mm cable, Black on Yellow, Loose multipack, 5 × 200

Why Choose the Partex PC20-BY Clip-On Chevron Cable Markers?

The Partex PC20-BY is a practical and reliable black-on-yellow clip-on chevron cable marker designed for clear identification of electrical wires and cables in industrial control panels, automation systems and electrical installations. Part of the established Partex PC clip-on cable marking range, these markers are designed for insulated cables with outside diameters of 3.0–4.0 mm, providing a convenient solution for identifying individual conductors without requiring cable disconnection.

The PC20-BY features a clip-on chevron marker design that allows identification characters to be fitted directly onto compatible insulated conductors. Its black characters on a yellow background provide high-contrast identification, helping electricians, panel builders and maintenance engineers recognise wiring references quickly and accurately.

Supplied as a loose multipack containing 5 × 200 markers, giving a total of 1,000 markers, the Partex PC20-BY is particularly suitable for electrical assembly workshops, industrial maintenance departments and control panel manufacturers requiring convenient access to cable identification characters. The clip-on installation method makes these markers useful for both new electrical installations and identification work on existing wiring.

Key Advantages

• High-contrast black-on-yellow identification improves conductor visibility and readability.

Reliable Clip-On Cable Identification for Industrial Electrical Systems

Clear and consistent conductor identification is essential for maintaining organised, serviceable electrical installations. The Partex PC20-BY black-on-yellow cable markers provide a practical method of identifying electrical wires, helping installation engineers and maintenance technicians follow wiring diagrams, locate connections and distinguish conductors during inspection and fault finding.

Unlike slide-on cable markers, which generally require access to a free cable end, the Partex PC20 clip-on marking system allows individual markers to be attached directly to suitable insulated conductors. This makes the PC20-BY particularly useful when adding identification to existing electrical wiring or updating cable references during maintenance and modification work.

The 3.0–4.0 mm cable diameter range supports secure selection for compatible cable insulation sizes, while the black-on-yellow marking format provides easily recognisable conductor references. Supplied in a convenient 5 × 200 loose multipack, these markers are well suited to panel-building workshops and maintenance teams carrying out repeated cable identification tasks. Marker selection should be based on the overall outside diameter of the insulated cable rather than conductor cross-sectional area alone.

Typical Applications

• Industrial electrical control panel wiring and identification.
• PLC cabinets and industrial automation systems.
• Switchgear and electrical distribution equipment.
• Machine building and OEM electrical assemblies.
• Motor control centres and control circuit wiring.
• Terminal block and conductor reference identification.
• Retrofitting cable identification onto existing wiring.
• Electrical maintenance, cable tracing and fault finding.
