The TE Connectivity 1SNK149012R0000 is an MC512PA pre-printed three-phase marker card designed for clear and consistent identification of SNK series terminal blocks in industrial electrical installations. This version features U1-U2-U3-V1-V2-V3-W1-W2-W3 (x10) plus U1 (x10) pre-printed markings in a vertical orientation, providing 100 markers for structured three-phase terminal identification.
Manufactured from durable white polyamide, the MC512PA marker card is designed around a 5.2 mm spacing for compatible SNK series terminal blocks. Its factory-applied alphanumeric markings reduce the need for individually produced labels, helping panel builders, machine manufacturers and electrical installers achieve uniform and easy-to-read identification throughout terminal assemblies.
The 1SNK149012R0000 measures 12 mm high, 5.2 mm wide, 5 mm long and 4.8 mm deep, with a product weight of 10 g. It is specified for operating and storage temperatures from -55 to +110 °C, making it suitable for demanding industrial panel, automation and electrical distribution environments.
Accurate terminal identification is essential in three-phase electrical systems, where U, V and W designations allow engineers and technicians to distinguish connection points quickly during assembly, commissioning and maintenance. The MC512PA 1SNK149012R0000 provides these alphanumeric designations in a factory-printed format, helping create orderly and easily traceable terminal assemblies.
The card contains 100 markers, with the U1-U2-U3-V1-V2-V3-W1-W2-W3 sequence repeated ten times together with ten additional U1 markers. Combined with its vertical mounting format and 5.2 mm spacing, this configuration provides a practical identification solution for compatible SNK series terminal block installations.
