Why Choose the TE Connectivity 1SNA230033R2600 RC55 Marker Card?

The TE Connectivity 1SNA230033R2600 is an ENTRELEC RC55 pre-printed terminal block marker card designed for clear and systematic identification of terminals in industrial electrical panels, control cabinets and automation systems. This version provides an ascending sequence from 301 to 400, giving 100 consecutive pre-printed identifiers on a single marker card.

Designed with a horizontal coding direction, the RC55 marker card allows panel builders and electrical engineers to identify terminal positions efficiently without individually producing each number. Its white marker surface provides clear visual contrast for the sequential numbering, supporting easier wiring, commissioning, circuit tracing, fault finding and maintenance.

The 1SNA230033R2600 uses 5 mm spacing and forms part of the established RC55 terminal identification system. With a card weight of 2.70 g, it provides a compact, ready-to-use solution for compatible terminal assemblies requiring consecutive numbering from 301 through 400.

Key Advantages

• Provides 100 ascending numbers from 301 to 400 on one marker card.
• Designed specifically for horizontal terminal block identification.
• 5 mm spacing for compatible terminal marking applications.
• White marker background provides clear contrast for easy number recognition.
• Pre-printed sequential format eliminates the need to produce numbers 301–400 individually.
• Ideal for organised terminal numbering in larger industrial electrical assemblies.

Key Features

• TE Connectivity ENTRELEC RC55 series.
• 301 → 400 ascending pre-printed sequence.
• 100 sequential markers per card.
• Horizontal coding direction.
• 5 mm spacing.
• White marker colour.
• Factory pre-printed for immediate terminal identification.
• Compact marker-card format for professional panel building.
• Designed for industrial terminal block marking applications.

Reliable Sequential Terminal Identification

Sequential terminal numbering is an important part of creating organised electrical panels and easily traceable wiring systems. The TE Connectivity ENTRELEC RC55 system provides factory pre-printed markers that allow engineers to apply consistent identification without having to create each terminal number separately.

The 1SNA230033R2600 supplies the complete ascending sequence from 301 through 400 in a horizontal format. With 100 consecutive identifiers and 5 mm spacing, it is particularly useful for larger terminal assemblies where structured numbering supports installation, circuit tracing, inspection and future maintenance.

Typical Applications

• Sequential industrial terminal block numbering.
• Electrical control panels and cabinets.
• PLC and industrial automation systems.
• Machine-building electrical assemblies.
• Switchgear and power distribution panels.
• Process control and instrumentation cabinets.
