1snk146181r0000 – mc512pa (100xr) h marker card

Why Choose the TE Connectivity / Entrelec 1SNK146181R0000 MC512PA Marker Card?

The TE Connectivity / Entrelec 1SNK146181R0000 is an MC512PA pre-printed terminal block marker card designed for clear and consistent identification of terminal connections in industrial control panels, machinery and automation systems. Pre-printed with the letter R repeated 100 times in a horizontal orientation, it provides a convenient ready-to-use marking solution for electrical panel and terminal strip applications.

The MC512PA uses factory-applied markings to provide uniform terminal identification without requiring individual labels to be manually written or printed. The repeated R marking is particularly useful where multiple terminals, circuits or connection points need to carry the same reference, helping panel builders create organised and easy-to-trace electrical installations.

Manufactured from white polyamide, the 1SNK146181R0000 features compact dimensions of 12 × 5.2 × 4.8 mm and a broad operating temperature range of -55 to +110 °C. Its material carries a UL 94V-2 flammability rating, providing a durable professional identification solution for demanding industrial electrical environments.

Consistent Letter Identification for Industrial Terminal Blocks

Clear terminal identification helps engineers match physical connection points with electrical drawings and simplifies circuit tracing during installation, commissioning, troubleshooting and maintenance. Pre-printed marker cards provide a consistent professional appearance throughout an electrical panel while removing the need to prepare each terminal marker individually.

The MC512PA 1SNK146181R0000 provides 100 pre-printed R markings in a horizontal format, making it particularly useful where the same letter reference is required across multiple terminals or connection points. Its compact dimensions, durable polyamide construction and wide operating temperature range make it a practical identification accessory for panel builders, machine builders and industrial automation engineers.

Typical Applications

• Terminal block identification in industrial control panels.
• Repeated R-reference terminal identification.
• PLC and automation cabinet wiring.
• Machine building and OEM electrical systems.
• Factory automation and production equipment.
• Electrical distribution and control cabinets.
