1sna234052r2100 – rc810 10x(111 a 120) vert,

Why Choose the TE Connectivity 1SNA234052R2100 RC810 Marker Card?

The TE Connectivity 1SNA234052R2100 is a pre-printed RC810 terminal block marker card designed for clear and consistent identification of terminals in electrical control panels, switchboards and industrial automation systems. Part of the ENTRELEC terminal marking range, this version carries the numbers 111–120 repeated 10 times in a vertical orientation.

Pre-printed terminal markers help panel builders and maintenance engineers identify individual connection points quickly and relate them to electrical drawings and circuit documentation. The RC810 system eliminates the need to print each identifier individually, providing a uniform and professional marking solution for compatible terminal assemblies.

The 1SNA234052R2100 is supplied as a white polyamide marker card for 8 mm spacing terminal block applications. Its vertical mounting format is suitable for vertically arranged terminal identification, while the UL 94V-2 flammability classification supports use in professional industrial electrical installations.

Clear Terminal Identification for Electrical Assemblies

Terminal marking provides a clear visual link between physical connection points and electrical schematics. Consistently identified terminals make wiring easier to inspect and help engineers work efficiently during panel assembly, commissioning, testing, troubleshooting and routine maintenance.

RC810 pre-printed markers are designed for compatible SNA and Solution series screw clamp, spring loaded screw clamp, spring clamp, distribution, power and ADO System terminal blocks, as well as screw clamp Miniblocks. The repeated 111–120 sequence is particularly useful where the same terminal numbering needs to be applied across multiple groups or assemblies.

Typical Applications

• Industrial electrical control panels.
• Terminal block and terminal strip assemblies.
• PLC and automation cabinets.
• Machine control systems.
• Switchboards and electrical distribution equipment.
• OEM machinery and panel-building applications.
