TE Connectivity 1SNA237004R2500 is a white polyamide RCAL85 pre-printed terminal block marker card containing 100 horizontally oriented markers with the 21–30 numbering sequence repeated ten times, 8 mm spacing and a UL 94V-2 flammability rating for compatible SNA and Solution series terminal blocks.
Why Choose the TE Connectivity RCAL85 1SNA237004R2500 Marker Card?
The TE Connectivity RCAL85 1SNA237004R2500 is a pre-printed terminal block marker card designed for clear and consistent identification of terminals in industrial electrical panels, control cabinets and automation systems. Part of the ENTRELEC RCAL85 marking range, this white marker card is horizontally pre-printed with the numbers 21 to 30, with the complete sequence repeated ten times.
RCAL85 pre-printed markers are designed for compatible SNA and Solution series spring-clamp terminal blocks and ADO System Miniblocks. Factory-applied numbering saves printing and manual marking time while helping panel builders, electrical engineers and maintenance technicians maintain consistent terminal references during installation, commissioning and servicing.
The 1SNA237004R2500 provides a card with 100 markers, comprising ten repetitions of the 21–30 sequence in a horizontal orientation. Its 8 mm spacing, white polyamide construction and UL 94V-2 flammability rating make it a practical identification accessory for professional industrial terminal assemblies.

Clear Identification for 8 mm Terminal Blocks
Accurate terminal identification helps simplify electrical installation, testing, troubleshooting and maintenance. Pre-printed RCAL85 marker cards provide consistent numerical references that allow engineers and technicians to locate wiring termination points quickly while maintaining an organised and professional control panel layout.
The 1SNA237004R2500 is designed for compatible 8 mm spacing SNA and Solution series spring-clamp terminal blocks and ADO System Miniblocks. Its repeated 21–30 format is particularly useful where the same numerical sequence is required across several terminal groups, providing a convenient factory-printed alternative to producing individual terminal markings.
Typical Applications
Industrial control panel terminal identification.
SNA and Solution series spring-clamp terminal blocks.
ADO System Miniblock identification.
Electrical distribution cabinets.
Automation and PLC control systems.
Machine-building electrical panels.
Terminal strip numbering and organisation.
