TE Connectivity 1SNA237020R2000 RCAL85 white polyamide terminal block marker card with 100 horizontal 8 mm pitch markers numbered 181–190 and repeated 10 times for compatible industrial terminal blocks.
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.
