1snk148102r0000 – mc512pa (100xu1) v marker card

Why Choose the TE Connectivity MC512PA 1SNK148102R0000 Marker Card?

The TE Connectivity 1SNK148102R0000, also known as MC512PA U1 (x100) Vertical, is a pre-printed terminal block marker card designed for clear and consistent identification of electrical terminals in industrial control panels, machinery and automation systems. Part of the TE Connectivity ENTRELEC SNK terminal marking range, it provides a professional identification solution for panel builders, machine manufacturers and electrical engineers.

This marker card contains 100 markers pre-printed with U1, eliminating the need to print or hand-write individual terminal identifiers. Its vertical coding direction and 5.2 mm spacing are designed for compatible SNK series terminal blocks, helping simplify panel construction, conductor identification, inspection, fault finding and maintenance.

Manufactured from durable white polyamide, the MC512PA measures 12 mm high × 5.2 mm wide × 4.8 mm deep with a length of 5 mm and a net weight of approximately 10 g. It is specified for operation from -55 to 110 °C and uses material rated UL 94 V-2, making it suitable for demanding industrial electrical environments.

Key Advantages

• Pre-printed with U1 repeated 100 times for consistent terminal identification.
• Vertical marking orientation for compatible terminal assemblies.

Clear Terminal Identification for Electrical Panels

Terminal marking accessories such as the TE Connectivity MC512PA provide an efficient method of identifying electrical connection points within control panels and terminal assemblies. Clearly marked terminals make electrical documentation easier to follow and allow engineers to locate connections more quickly during installation, testing, inspection, fault finding and maintenance.

The MC512PA pre-printed marker format provides consistent identification without the need for handwritten labels or on-site marker printing. With U1 repeated across 100 markers, a vertical coding direction and 5.2 mm spacing, this version is particularly useful for compatible SNK terminal assemblies requiring repeated U1 conductor, phase or circuit identification.

Typical Applications

• Industrial electrical control panels.
• SNK series terminal block identification.
• U1 conductor and terminal identification.
• Motor control and electrical distribution panels.
• PLC and industrial automation cabinets.
• Machine building and OEM electrical systems.
• Switchgear and process control installations.
