Why Choose the TE Connectivity MC512PA B (x100) Horizontal Marker Card?
The TE Connectivity MC512PA B (x100) Horizontal, part number 1SNK146021R0000, is a white pre-printed terminal marker card designed for clear identification of compatible ENTRELEC terminal blocks and terminal strips. Factory printed with the letter B repeated 100 times, it provides a convenient ready-to-use marking solution for industrial electrical panels, automation cabinets and control systems.
The MC512PA marker format has a compact 5.2 mm width and measures approximately 12 mm high, 5 mm long and 4.8 mm deep. The letter B is printed in a horizontal orientation, providing consistent component and circuit identification while eliminating the need to individually print repetitive B markers during panel construction.
Manufactured from durable polyamide, the 1SNK146021R0000 is rated for operation from -55 to +110 °C and carries a UL 94V-2 flammability rating. Its combination of pre-printed identification, compact dimensions and industrial-grade construction makes it a practical marking accessory for organised terminal assemblies in demanding electrical installations.

Clear Pre-Printed Terminal Identification
Consistent terminal identification helps installers, commissioning engineers and maintenance personnel understand and trace electrical circuits efficiently. The TE Connectivity MC512PA 1SNK146021R0000 provides 100 pre-printed B markings, allowing repeated terminal or circuit references to be applied without producing individual labels during panel assembly.
The compact 5.2 mm-wide marker format integrates neatly with compatible terminal assemblies, while the white background and horizontally printed B character provide clear visual identification. Durable polyamide construction and the broad -55 to +110 °C operating range support reliable use in industrial automation, machine control, instrumentation and electrical distribution environments.
Typical Applications
- ENTRELEC terminal block and terminal strip identification.
- Industrial electrical control panels.
- PLC and automation cabinets.
- Switchboards and distribution panels.
- Machine control wiring identification.
- Process control and instrumentation panels.
- Repeated letter B terminal or circuit identification.
