The TE Connectivity MC512PA B (x100) Vertical, part number 1SNK146022R0000, is a white pre-printed terminal marker card from the ENTRELEC marking accessory range. It is factory printed with the letter B repeated 100 times, providing a convenient ready-to-use solution for repetitive identification of compatible terminal blocks and terminal strips in industrial electrical installations.
The MC512PA format combines compact dimensions with a vertical marking orientation. The marker format measures 12 mm high, 5 mm long, 5.2 mm wide and 4.8 mm deep, with a 5.2 mm spacing suited to compatible terminal assemblies. Factory-applied B markings remove the need to individually print repetitive identifiers during panel assembly, helping maintain consistent labelling across an installation.
Manufactured from durable white polyamide, the 1SNK146022R0000 weighs approximately 10 g, operates across a temperature range of -55 to +110 °C and carries a UL 94V-2 flammability rating. These characteristics make it a practical identification accessory for control panels, automation systems, machinery and electrical distribution equipment.
Consistent terminal identification helps panel builders, commissioning engineers and maintenance personnel trace circuits and components efficiently. The TE Connectivity MC512PA 1SNK146022R0000 provides 100 pre-printed B markings in a vertical orientation, making it particularly useful where the same alphabetical reference is required repeatedly throughout a terminal assembly.
The compact 5.2 mm-wide marker format integrates neatly with compatible terminal blocks, while the white background and factory-applied B character provide clear visual identification. Its polyamide construction, UL 94V-2 classification and broad operating temperature range support use in demanding industrial electrical environments.
