1sna237020r2000 – rcal85 10x(181a190) horiz,

Why Choose the TE Connectivity RCAL85 1SNA237020R2000 Marker Card?

The TE Connectivity RCAL85 1SNA237020R2000 is a pre-marked terminal block marker card designed for clear and consistent identification of compatible Entrelec terminal blocks in industrial control panels and electrical installations. Part of the RCAL85 marking system, this horizontal version provides the numbers 181–190 repeated 10 times across a card containing 100 individual markers.

RCAL85 markers provide a convenient way to identify terminal positions during panel building, commissioning and maintenance. The factory-applied numbering eliminates the need to mark individual labels manually, helping installers create neat, consistent and easily traceable terminal assemblies.

The 1SNA237020R2000 is manufactured from white polyamide and has an 8 mm marker pitch. It is designed for compatible spring-clamp terminal blocks and ADO System miniature terminal blocks within the SNA and Solution ranges, making it a practical identification accessory for professional automation and control-panel applications.

Clear Identification for Terminal Block Assemblies

Accurate terminal identification helps engineers trace circuits efficiently during installation, testing, fault finding and maintenance. RCAL85 pre-marked cards provide ready-to-use identification for compatible terminal assemblies, reducing manual marking work while supporting a professional and organised panel layout.

The RCAL85 system is intended for marking compatible spring-clamp terminals and ADO System miniature terminal blocks. With its 8 mm pitch and pre-printed sequential numbering, the 1SNA237020R2000 is particularly useful where terminal positions 181 through 190 need to be repeated across multiple circuits or terminal groups.

Typical Applications

• Industrial electrical control panels.
• Automation and machine control cabinets.
• Terminal block identification.
• PLC and instrumentation panels.
• Power distribution and control assemblies.
• Machine building and OEM electrical systems.
