Why Choose the TE Connectivity 1SNA230166R0000 RC55 Marker Card?

The TE Connectivity 1SNA230166R0000 is a pre-printed RC55 terminal block marker card designed for clear and consistent identification of electrical connections in industrial control panels, switchboards and automation equipment. Part of the established ENTRELEC RC55 marking range, this version is supplied with the letter Q repeated 100 times for convenient identification of multiple terminal positions.

Designed for professional terminal marking applications, the 1SNA230166R0000 features horizontal coding on a white polyamide marker card. Its ready-to-use pre-printed format eliminates the need to individually print or hand-write repetitive terminal identifiers, helping panel builders create neat and consistent electrical assemblies.

The RC55 marker card has a 5 mm marking pitch and compact dimensions of approximately 60 × 61 × 2 mm. With a product weight of approximately 2.7 g and a UL 94 V-2 flammability classification, it provides a lightweight and practical marking solution for compatible terminal block installations.

Reliable Terminal Identification for Industrial Electrical Systems

Accurate terminal identification helps simplify installation, commissioning, fault finding and ongoing maintenance of electrical systems. The TE Connectivity RC55 marking range provides ready-to-use identification accessories for creating clearly organised terminal assemblies within industrial control and distribution equipment.

With the letter Q repeated across 100 marking positions, the 1SNA230166R0000 is particularly useful where the same alphabetic identifier must be applied consistently across multiple terminals. Its horizontal orientation and 5 mm pitch provide an efficient solution for compatible terminal arrangements while helping maintain a professional and easily readable panel layout.

Typical Applications

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