1sna116629r2200 – end sect for 115-479.23

Why Choose the TE Connectivity 1SNA116629R2200 FEM4A End Section?

The TE Connectivity 1SNA116629R2200, also identified as FEM4A, is a dedicated grey end section for Entrelec SNA DIN-rail terminal blocks. Designed specifically for compatible M4/6.4A-family terminals, it closes the open side of a terminal block to provide an insulated, neat and professionally finished terminal row.

The FEM4A is compatible with M4/6.4A, M4/6.4A.P, M4/6.SBT.4A and M4/6.SNBT.4A terminal blocks, including the associated 1SNA115479R2300 M4/6.4A. Its purpose-designed profile allows it to snap onto the terminal assembly while following the contours of the compatible SNA blocks.

Manufactured from grey polyamide insulating material with a UL94 V-0 flammability rating, the 1SNA116629R2200 is designed for industrial electrical environments. At approximately 3 mm thick and 3.8 g in weight, it adds minimal space to the completed terminal row while providing the required end-section function.

Completing and Insulating SNA Terminal Rows

Many modular terminal blocks have an open side when installed individually or at the end of a terminal row. A correctly matched end section closes this exposed profile and provides the insulating separation required to complete the assembly. The FEM4A is shaped specifically for compatible M4/6.4A-family terminals, providing a clean fit without relying on a generic barrier or cover.

The polyamide UL94 V-0 construction provides a durable insulating barrier while the compact 3 mm profile minimises additional DIN-rail space. This makes the 1SNA116629R2200 a practical accessory for new terminal installations as well as maintenance, modification and expansion of existing Entrelec SNA terminal rows.

Typical Applications

• End insulation for M4/6.4A terminal blocks.
• Industrial electrical control panels.
• PLC and automation cabinets.
• Machine-control terminal rows.
• Switchgear and distribution assemblies.
• Instrumentation and signal wiring panels.
• OEM electrical-panel construction and maintenance.
