1sna230194r2500 – rc55 (100 x o) vert,

Why Choose the TE Connectivity 1SNA230194R2500 RC55 Terminal Block Markers?

The TE Connectivity 1SNA230194R2500 is an RC55 pre-printed terminal block marker card designed for clear and consistent identification of terminal connections in industrial electrical panels, control cabinets and automation systems. Part of the established Entrelec RC55 marking range, this version contains the letter O repeated 100 times in a vertical marking orientation.

Clear terminal identification helps panel builders, electrical installers and maintenance engineers trace wiring efficiently during assembly, commissioning and servicing. The pre-printed RC55 format provides ready-to-use identification without the need to print individual labels, helping maintain consistent and easily readable marking throughout compatible terminal block assemblies.

The 1SNA230194R2500 provides 100 identical “O” markers on a white polyamide marker card with 5 mm spacing. The card measures approximately 60 × 2 × 61 mm, has a net weight of approximately 2.7 g and uses material with a UL 94 V-2 flammability classification.

Clear Identification for Industrial Terminal Blocks

Terminal marking is an important part of professionally assembled electrical control systems. Clearly identified terminals allow engineers to match installed wiring with electrical schematics, simplify circuit tracing and reduce the time required for inspection, troubleshooting and maintenance.

The RC55 range provides convenient pre-printed identification for compatible terminal block installations. With 100 identical “O” markings arranged vertically at 5 mm spacing, the 1SNA230194R2500 provides a practical solution wherever repeated letter identification is required across industrial terminal assemblies.

Typical Applications

• Industrial electrical control panels.
• Terminal block assemblies.
• Machine control cabinets.
• PLC and automation panels.
• Switchgear and electrical distribution equipment.
• Process control installations.
• Industrial wiring identification and maintenance.
