1snk146102r0000 – mc512pa (100xj) v marker card

Why Choose the TE Connectivity / Entrelec 1SNK146102R0000 MC512PA Marker Card?

The TE Connectivity / Entrelec 1SNK146102R0000 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 J repeated 100 times in a vertical orientation, it provides a ready-to-use identification solution for compatible Entrelec SNK terminal block assemblies.

Designed for the Entrelec SNK series, the MC512PA uses factory-applied markings to provide uniform identification without requiring individual labels to be manually written or printed. The repeated J marking is particularly useful where multiple terminals or connection points need to carry the same reference, helping panel builders maintain clear and consistent identification throughout an electrical installation.

Manufactured from white polyamide, the 1SNK146102R0000 features a 5.2 mm pitch, compact 12 × 5.2 × 4.8 mm dimensions and a broad operating temperature range of -55 to +110 °C. Its material carries a UL 94V-2 flammability rating, providing a durable professional marking solution for industrial electrical and automation environments.
