1sna231700r1100 – rc510tt-yl

Why Choose the TE Connectivity RC510TT-YL Blank Yellow Marker Card?

The TE Connectivity 1SNA231700R1100, also identified as RC510TT-YL, is a blank ENTRELEC HTP600 terminal block marker card designed for customised identification of terminal blocks and terminal strips in electrical control panels, automation systems and industrial installations. Its blank marking surface allows panel builders and engineers to create application-specific terminal references using compatible marking equipment.

As part of the ENTRELEC HTP600 marking system, the RC510TT-YL provides a coordinated solution for professional electrical identification. Unlike pre-printed marker cards with fixed letters or numbers, its blank format gives users the flexibility to create project-specific identifiers that correspond directly with wiring diagrams, circuit references and equipment documentation.

The 1SNA231700R1100 is supplied in a highly visible yellow colour and features a 5 × 10 mm marker format. Designed for demanding industrial environments, it offers an operating temperature range of -30 to 120 °C and a UL 94V-0 flammability rating.

Custom Identification for Industrial Terminal Blocks

Clear terminal identification helps simplify electrical installation, commissioning, troubleshooting and maintenance. Blank marker cards allow individual identifiers to be created to correspond with project wiring diagrams and circuit numbering systems, helping engineers locate connections and trace circuits efficiently.

The yellow RC510TT-YL provides an additional visual distinction compared with standard white marking products, making it useful where particular terminal groups or circuits need to stand out. Its HTP600 compatibility allows customised marking to be incorporated into a coordinated professional identification system.

Typical Applications

• Electrical control panels and switchboards.
• Industrial automation cabinets.
• Terminal block and terminal strip identification.
• Custom circuit and connection-point marking.
• PLC and instrumentation panels.
• OEM machinery and electrical panel building.
