1sna237049r0100 – rcal85 10x(81a90) vert,

Why Choose the TE Connectivity RCAL85 1SNA237049R0100 Terminal Block Marker Card?

The TE Connectivity RCAL85 1SNA237049R0100 is a pre-printed terminal block marker card designed for clear and consistent identification of electrical terminals in industrial control panels, switchgear and automation systems. Part of the established Entrelec RCAL85 marking system, this version provides the numbers 81 to 90 repeated ten times with a vertical marking orientation.

The RCAL85 series provides ready-to-use terminal identification that helps panel builders save installation time while maintaining organised and easily traceable wiring. Its pre-printed format eliminates the need to individually print each terminal number, supporting efficient installation, commissioning, troubleshooting and routine electrical maintenance.

With 81–90 numbering repeated ten times, a vertical orientation and 8 mm spacing, the 1SNA237049R0100 provides a practical identification solution for compatible SNA and Solution series terminal blocks. The white marker format provides clear character visibility and is designed for professional industrial electrical installations.

Reliable Terminal Identification for Industrial Control Panels

Terminal block markers provide an essential method of identifying electrical connection points inside control panels and switchgear. Clear sequential numbering helps installers, commissioning engineers and maintenance personnel trace circuits efficiently, reducing wiring errors and simplifying fault finding and future servicing.

The RCAL85 series provides a broad range of pre-printed cards for compatible spring-clamp terminal blocks and ADO System Miniblocks within the SNA and Solution families. The 1SNA237049R0100 supplies the 81–90 sequence ten times in a vertical format, making it particularly useful where repeated groups of terminals require consistent numerical identification.

Typical Applications

• Industrial control panels and electrical cabinets.
• Terminal block and wiring identification.
• Machine-building and OEM automation systems.
• Switchgear and electrical distribution assemblies.
• PLC and industrial automation panels.
• Sequential circuit and terminal numbering.
