1snk140131r0000 – mc512pa 10x[121->130] h marker card

Why Choose the TE Connectivity MC512PA 121–130 Horizontal Marker Card?

The TE Connectivity MC512PA, part number 1SNK140131R0000, is a pre-printed horizontal terminal block marker card designed for clear and consistent identification of compatible ENTRELEC terminal blocks and terminal strips. This specific marker card is factory printed with the numbers 121 through 130 repeated ten times, providing 100 individual terminal markers for repetitive circuit identification.

Designed around a 5.2 mm spacing, the MC512PA provides a compact marking solution for compatible terminal assemblies. The horizontal print orientation supports easy reading across terminal strips, while the pre-printed numbering removes the need to produce the 121–130 sequence separately during panel assembly.

The markers are manufactured from durable white polyamide and carry a UL 94 V-2 flammability classification. With an operating temperature range of -55 to +110 °C, the 1SNK140131R0000 is suitable for terminal identification across a wide variety of industrial control, automation and electrical distribution applications.

Fast and Consistent Pre-Printed Terminal Identification

Accurate terminal identification helps engineers match physical connections with wiring diagrams and circuit documentation during installation, commissioning and maintenance. The MC512PA 1SNK140131R0000 supplies ten complete sets of numbers 121–130, making it particularly useful where the same terminal sequence is repeated across several circuits or assemblies.

Its horizontal marking orientation and 5.2 mm spacing provide a neat identification solution for compatible terminal blocks. Factory-applied numbering also ensures consistent presentation throughout an electrical panel while reducing the preparation required during panel building.

Typical Applications

• Identification of compatible ENTRELEC terminal blocks and terminal strips.
• SNK series terminal assemblies.
• Industrial control and automation panels.
• Electrical distribution cabinets.
• Machine-building electrical systems.
• Factory and process automation equipment.
• Instrumentation and control wiring.
• Panel building, commissioning and maintenance.
