1sna230012r2100 – rc55 10x(101 a 110) horiz,

Why Choose the TE Connectivity RC55 1SNA230012R2100 Marker Card?

The TE Connectivity 1SNA230012R2100 is an ENTRELEC RC55 pre-printed terminal block marker card designed for clear and consistent identification of terminals in industrial electrical panels and automation systems. This version is pre-printed with the numbers 101 to 110, repeated 10 times, providing a total of 100 sequentially organised markers for horizontal terminal identification.

The RC55 marking system provides panel builders and electrical engineers with a convenient alternative to manually producing individual terminal labels. Repeating the 101 to 110 sequence ten times makes the 1SNA230012R2100 particularly useful for installations containing multiple terminal groups that follow the same numbering arrangement.

Designed with a 5 mm pitch, the RC55 marker card is intended for horizontal coding of compatible terminal block assemblies. The markers are supplied in white and carry a UL 94V-2 flammability rating, making them suitable for organised terminal identification in professional industrial control and electrical distribution installations.

Key Advantages

• Pre-printed RC55 terminal block marker card for efficient identification.
• Number sequence 101 to 110 repeated 10 times.
• Provides 100 pre-printed markers across ten repeated sequences.
• Horizontal coding orientation for compatible terminal block assemblies.
• 5 mm pitch suited to compatible terminal configurations.
• Pre-printed format helps reduce terminal marking and panel assembly time.

Key Features

• TE Connectivity ENTRELEC RC55 series.
• 101 to 110 numbering sequence.
• Sequence repeated 10 times.
• 100 individual markers per card.
• Horizontal orientation.
• 5 mm marker pitch.
• White marker colour.
• UL 94V-2 flammability rating.

Sequential Identification for Industrial Control Panels

Accurate terminal numbering helps simplify electrical panel assembly, commissioning, inspection, maintenance and fault finding. The RC55 1SNA230012R2100 provides a ready-made 101 to 110 numbering sequence, eliminating the need to individually produce these commonly required terminal identifiers.

Because the complete 101 to 110 sequence is repeated ten times, a single card can be used across multiple terminal groups with matching numbering arrangements. The 5 mm pitch and horizontal coding format make the RC55 suitable for structured identification in industrial control panels, machinery, switchgear and automation equipment.

Typical Applications

• Industrial electrical control panels.
• Terminal block and terminal strip assemblies.
• Automation and machinery control cabinets.
• Power distribution and switchgear panels.
• PLC and instrumentation wiring systems.
• Repeated terminal groups numbered from 101 to 110.
• OEM machinery and electrical panel manufacturing.
