The TE Connectivity MC512-YL, part number 1SNK140004R0000, is a yellow blank marker card designed for clear and durable identification of compatible ENTRELEC terminal blocks and terminal strips. Part of the ENTRELEC HTP600 marking range, it provides a professional solution for organising terminal assemblies in industrial control panels, switchboards and automation systems.
Manufactured from durable polycarbonate, the MC512-YL combines excellent marking durability with a UL 94V-0 flammability rating. The markers are supplied blank for customised identification and accommodate up to 3 printed digits horizontally or 8 digits vertically, allowing terminal references and circuit identifiers to be applied according to panel requirements.
Each marker measures approximately 12 × 5.2 × 4.8 mm, with the MC512 format designed around 5.2 mm terminal-block spacing. The marker card operates across a wide temperature range of -55 to +110 °C, making it suitable for demanding industrial environments where durable and easily readable terminal identification is required.
Terminal marking is essential for creating organised electrical panels that can be installed, inspected and maintained efficiently. The TE Connectivity MC512-YL provides a durable blank marking surface that allows individual terminals and circuits to be identified according to project-specific wiring diagrams and panel documentation.
The yellow polycarbonate construction provides both visual differentiation and durability in demanding industrial environments. With space for up to three characters horizontally or eight characters vertically, MC512 markers support concise terminal references while their 12 mm marking height provides a generous surface for clear identification.
