1snk140051r0000 – mc512pa 10x[41->50] h marker card

Why Choose the TE Connectivity MC512PA 41–50 Horizontal Marker Card?

The TE Connectivity MC512PA, part number 1SNK140051R0000, is a pre-printed horizontal terminal block marker card designed for clear identification of compatible ENTRELEC terminal blocks. The card is pre-marked with the numbers 41 through 50 repeated ten times, providing a convenient ready-to-use identification solution for repetitive terminal numbering in industrial electrical panels.

The MC512PA marker format has a 5.2 mm width and is associated with 5.2 mm terminal spacing, making it suitable for compatible SNK series terminal arrangements. With 100 individual markers per card, the 41–50 sequence is repeated ten times, allowing multiple groups of terminals to be identified consistently from a single marker card.

Manufactured from durable white polyamide, the MC512PA is rated UL 94 V-2 for flammability and operates across a broad temperature range of -55 to +110 °C. Its horizontal orientation and factory-applied numbering help reduce marking time while maintaining consistent, professional terminal identification.

Key Advantages

• Pre-printed 41–50 numbering repeated ten times for immediate installation.
• 100 individual markers per card support repetitive terminal identification.
• Horizontal orientation provides easy-to-read terminal references.
• Designed around 5.2 mm terminal spacing for compatible terminal blocks.
• White polyamide construction provides a durable identification surface.
• Wide -55 to +110 °C operating temperature range.
• Pre-printing eliminates the need to produce common 41–50 number sequences manually.

Fast and Consistent Pre-Printed Terminal Identification

Clear terminal identification is essential for efficient installation, commissioning and maintenance of industrial electrical equipment. The MC512PA 1SNK140051R0000 provides the numbers 41–50 repeated ten times, allowing technicians to identify multiple groups of terminals without individually printing each marker.

Its horizontal orientation and compact 5.2 mm width provide a neat identification solution for compatible terminal assemblies. Consistent factory-applied markings also help engineers correlate physical terminal positions with wiring diagrams, circuit schedules and maintenance documentation.

Typical Applications

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