Multi Connection Terminal Block, 4mm², 4 Wire, Yellow – CMC2-2Y

Product Description

CMC2-2Y is a high-visibility terminal marker card designed for accurate terminal numbering, circuit identification, and organized wiring management in industrial electrical panels and control systems. In electrical installations, clear identification of terminal points is one of the most important requirements for safe operation, efficient maintenance, and professional panel organization. This marker card is specially developed to provide a compact and reliable marking solution for terminal blocks used in control panels, switchboards, PLC systems, automation cabinets, machine wiring systems, relay panels, instrumentation circuits, and industrial electrical distribution boards.

In modern electrical panels, hundreds of terminals may be installed in a compact area, each carrying different control signals, neutral circuits, relay outputs, power distribution points, or field wiring connections. Without proper terminal identification, troubleshooting becomes difficult, maintenance takes longer, and the risk of wiring errors increases significantly. CMC2-2Y is used to eliminate this problem by providing a dedicated terminal marking solution that allows electricians and engineers to assign visible identification to each terminal point in a neat and structured way.

The main reason this product is used is to create organized terminal numbering and circuit identification systems inside electrical panels. When each terminal has a clear number or circuit code, engineers can easily match physical wiring with electrical schematics, maintenance teams can identify circuits quickly, and troubleshooting becomes safer and more efficient. This reduces downtime and improves electrical servicing productivity.

The functional working design of CMC2-2Y is based on a snap-fit terminal marker system. The marker card is designed to fit into compatible marker slots provided on terminal blocks. Once installed, it provides a flat visible marking surface where numerical, alphabetical, or coded identification can be printed or marked. This visible identification helps in circuit tracing, terminal verification, and electrical documentation matching.

One of the key functional features of CMC2-2Y is its 2 mm compact marker width, which allows efficient identification in densely packed terminal assemblies. In high-density control panels, terminal accessories must be compact while maintaining visibility and readability. This marker card is engineered to meet this requirement, making it ideal for organized panel layouts.

The yellow marker color provides an important identification advantage. Color-coded marker systems improve visual recognition inside electrical panels and make specific circuit groups easier to identify. Yellow color provides high visibility and supports better differentiation during panel inspection, maintenance, and troubleshooting.

Another major safety advantage of CMC2-2Y is that it reduces terminal identification mistakes. In industrial electrical systems, incorrect terminal identification can lead to wrong wire disconnection, maintenance delays, circuit faults, and operational risk. A properly marked terminal system improves maintenance safety and reduces servicing errors by helping technicians locate the correct connection point quickly.

The marker card is manufactured using high-grade engineering thermoplastic material, which offers strong mechanical stability, excellent insulation properties, and long service life. The material is non-conductive, making it safe for use inside electrical panels where identification accessories must remain electrically insulated.

Its flat and smooth printable marking surface supports numerical, alphanumeric, and coded identification systems based on panel design requirements. This flexibility makes it suitable for use in control panels, industrial automation systems, OEM electrical assemblies, machine control circuits, and electrical wiring systems requiring organized labeling.
