TERMINAL MARKER 5×12 PRINTED 301-400

Why Choose the TE Connectivity MC512PA 301→400 Horizontal Terminal Marker Card?

The TE Connectivity MC512PA 301→400 Horizontal, part number 1SNK145041R0000, is a pre-printed terminal block marker card designed for clear and consistent identification of compatible ENTRELEC terminal blocks and terminal strips. Factory printed with the sequential numbers 301 through 400, it provides a convenient ready-to-use marking solution for industrial electrical panels, automation cabinets and control systems.

The MC512PA marker format combines a compact 5.2 mm width with a 12 mm height, allowing individual markers to integrate neatly with compatible terminal assemblies. The 301–400 sequence is printed in a horizontal orientation, with the format accommodating up to three digits horizontally, making it ideally suited to this three-digit terminal numbering range.

Manufactured from durable white polyamide, the 1SNK145041R0000 is rated for operation from -55 to +110 °C and has a UL 94V-2 flammability rating. Its factory-applied numbering eliminates the need to print individual references during panel construction, helping improve consistency and efficiency in professional terminal identification applications.

Clear Sequential Terminal Identification

Accurate terminal marking makes electrical installations easier to assemble, commission, inspect and maintain. The TE Connectivity MC512PA 1SNK145041R0000 provides the complete sequential numbering range from 301 through 400, allowing installers to identify terminal positions consistently without producing individual labels during panel construction.

The compact 5.2 × 12 mm marker format integrates neatly with compatible terminal assemblies, while the white background and horizontally printed three-digit references provide clear visual identification. Durable polyamide construction and the broad -55 to +110 °C operating range support use in demanding industrial automation, machine control and electrical distribution environments.
