The TE Connectivity MC812PA 1SNK166041R0000 is a pre-printed horizontal terminal block marker card designed for clear and consistent identification in industrial electrical panels and automation systems. Part of the TE Connectivity ENTRELEC SNK marking range, this exact MC812PA variant is pre-printed with the letter D repeated 100 times, making it ideal for installations where multiple terminals or connection points require the same letter designation.
Designed for 8 mm spacing, the MC812PA marker card provides a convenient ready-printed alternative to producing individual terminal labels. Its horizontal orientation presents the letter D clearly across compatible terminal assemblies, helping panel builders create organised wiring systems and improve identification during assembly, commissioning, troubleshooting and maintenance.
The 1SNK166041R0000 is manufactured from durable white polyamide and carries a UL 94V-2 flammability rating. It measures 12 mm high, 8 mm wide, 7.6 mm long and 7.6 mm deep, weighs 14 g and is specified for operation from -55 to +110 °C.
Consistent terminal identification makes electrical panels easier to assemble, inspect, commission and maintain. The TE Connectivity MC812PA range provides commonly required letters, numbers and symbols already printed onto terminal markers, helping panel builders reduce preparation time while maintaining clear and uniform identification throughout an electrical assembly.
With 100 individual D markings, the 1SNK166041R0000 is particularly useful where the same letter designation is required repeatedly across circuits, connection points or equipment groups. Its 8 mm spacing, horizontal format and durable polyamide construction make it a practical identification accessory for compatible ENTRELEC SNK terminal block installations.
