1sna230200r2700 – rc55 (100 x u) vert,

Why Choose the TE Connectivity 1SNA230200R2700 RC55 Marker Card?

The TE Connectivity 1SNA230200R2700 is a pre-printed RC55 terminal block marker card designed for clear and consistent identification of electrical terminals in industrial control panels, switchboards and automation equipment. Part of the established TE Connectivity ENTRELEC RC55 marking range, this version is pre-printed with the letter U repeated 100 times, providing convenient identification where the same alphabetic designation is required across multiple terminal positions.

Designed for professional terminal block identification, the 1SNA230200R2700 features a vertical coding direction and a white marker surface for clear visual recognition within terminal assemblies. The factory pre-printed format helps reduce manual labelling work during panel construction, commissioning and maintenance while supporting neat and standardised electrical installations.

The RC55 marker card uses 5 mm spacing and is manufactured from durable polyamide. With dimensions of approximately 60 × 2 × 61 mm, a net weight of approximately 2.7 g and a UL 94 V-2 flammability classification, it provides a compact and practical identification solution for compatible terminal block assemblies.

Reliable Terminal Identification for Industrial Electrical Systems

Clear terminal identification is essential for efficient electrical panel assembly, commissioning, troubleshooting and ongoing maintenance. TE Connectivity ENTRELEC RC55 pre-printed markers provide a practical way to create organised terminal assemblies, helping engineers and technicians identify connection points quickly while maintaining a professional panel layout.

With the letter U repeated across 100 marking positions, the 1SNA230200R2700 is particularly useful where a common alphabetic identifier needs to be applied consistently to multiple terminals. Its vertical format and 5 mm spacing make it a convenient identification accessory for compatible terminal block arrangements in industrial electrical and automation systems.

Typical Applications

• Industrial control panel terminal identification.
• Electrical switchboards and distribution panels.
• Machine control and factory automation systems.
• Terminal block and terminal strip marking.
• OEM electrical panel manufacturing.
• Process control and instrumentation cabinets.
• Maintenance and replacement terminal identification.
