The TE Connectivity 1SNK146151R0000, also known as MC512PA O (x100) Horizontal, is a pre-printed terminal block marker card designed for clear and consistent identification of terminals in industrial electrical panels and automation systems. Part of the TE Connectivity ENTRELEC terminal block marking range, it provides a practical identification solution for panel builders, machine manufacturers and electrical engineers.
This marker card is factory printed with the letter O repeated 100 times, eliminating the need to print or hand-write individual terminal identifiers. Its horizontal orientation provides clear, consistent marking when fitted to compatible terminal assemblies, helping simplify panel construction, circuit 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 and weighs approximately 10 g. It is specified for an operating temperature range of -55 to 110 °C and uses UL 94V-2 rated material, making it suitable for demanding industrial electrical environments.
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 circuits 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 the letter O repeated 100 times and a horizontal orientation, this version is particularly useful for terminal assemblies requiring repeated letter identification across machinery, switchgear and industrial automation installations.
