Why Choose the TE Connectivity RC55 901–1000 Vertical Marker Card?
The TE Connectivity 1SNA230069R1200 is a pre-marked RC55 terminal block marker card designed for clear and permanent identification of terminal blocks in industrial electrical panels and control systems. Part of the established TE Connectivity ENTRELEC RC55 marking system, this marker card provides sequential numbering from 901 to 1000 in a vertical orientation for fast identification during installation, commissioning and maintenance.
RC55 markers are designed for use with compatible ENTRELEC SNA and Solution series terminal blocks, providing a neat and consistent method of identifying individual connection points. The pre-printed format eliminates the need to manually produce individual labels, helping reduce installation time while improving the organisation and readability of terminal assemblies.
The 1SNA230069R1200 marker card is supplied in white with clearly printed 901–1000 sequential markings. Its vertical coding direction is particularly useful where the terminal block layout requires vertically oriented identification, providing clear visibility within densely populated control cabinets and distribution panels.

Clear Identification for Industrial Terminal Assemblies
Reliable terminal identification is essential in electrical control panels, helping installers and maintenance engineers trace circuits quickly and accurately. Pre-marked RC55 cards provide consistent identification without requiring each terminal marker to be individually printed or handwritten.
The vertical 901–1000 numbering sequence makes the 1SNA230069R1200 particularly suitable for larger terminal assemblies where high terminal numbers are required. Its compatibility with established ENTRELEC terminal block systems makes it a practical accessory for new panel construction, equipment upgrades and maintenance work.
Typical Applications
- Industrial electrical control panels.
- Automation and PLC control cabinets.
- Terminal block assemblies and terminal strips.
- Power distribution panels.
- Machine building and OEM electrical systems.
- Industrial maintenance and panel refurbishment.
