1sna230064r0500 – rc55 (401 a 500) vert,

Why Choose the TE Connectivity 1SNA230064R0500 RC55 Marker Card?

The TE Connectivity 1SNA230064R0500 is an ENTRELEC RC55 pre-printed terminal block marker card designed for clear and systematic terminal identification in industrial electrical panels, control cabinets and automation systems. This version provides an ascending sequence from 401 to 500, giving 100 consecutive pre-printed identifiers on a single marker card.

Designed specifically for vertical terminal identification, the RC55 marker card enables panel builders and electrical engineers to apply organised sequential numbering without producing each terminal identifier individually. Its white marker format provides clear visual contrast for the printed numbers, supporting efficient wiring, commissioning, circuit tracing, inspection and maintenance.

The 1SNA230064R0500 forms part of the established ENTRELEC RC55 terminal marking system and carries a UL 94V-2 flammability rating. With 100 ascending markers from 401 through 500 and a card weight of 2.70 g, it provides a compact, ready-to-use identification solution for compatible industrial terminal block assemblies.

Key Advantages

• Provides 100 ascending numbers from 401 to 500 on one marker card.
• Designed specifically for vertical terminal block identification.
• Factory pre-printed numbering eliminates the need to produce identifiers 401–500 individually.
• White marker format provides clear visual contrast for easy number recognition.
• UL 94V-2 flammability rating for professional electrical marking applications.
• Ideal for structured sequential numbering across larger industrial terminal assemblies.

Reliable Sequential Terminal Identification

Sequential terminal numbering is an important part of creating organised electrical panels and easily traceable wiring systems. TE Connectivity ENTRELEC RC55 pre-printed marker cards provide factory-applied identification, allowing engineers to maintain consistent terminal references while reducing the time required to prepare individual markers.

The 1SNA230064R0500 supplies the complete ascending sequence from 401 through 500 in a vertical format. With 100 consecutive identifiers available on one card, it is particularly useful for larger terminal assemblies where structured numbering supports installation, commissioning, 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.
