The TE Connectivity AL2-H8.5-M2.6 1SNA167319R0600 is a compact 2 mm test socket designed for compatible Entrelec SNA screw-clamp terminal blocks. It provides a dedicated electrical test point that allows engineers and maintenance personnel to connect compatible test equipment directly to a terminal block without disturbing the permanent field wiring.
The AL2 test socket is installed by screwing into the tapped hole in the connector bar of a compatible terminal block. Its M2.6 mounting thread and approximately 8.5 mm height identify this specific AL2 configuration, helping ensure correct selection when replacing or adding test accessories to existing Entrelec SNA terminal assemblies.
Designed for use with 2 mm diameter test plugs such as the Entrelec FC2, the 1SNA167319R0600 provides a practical interface for voltage measurement, diagnostics, commissioning and maintenance. Its compact construction and approximately 1 g net weight make it an unobtrusive accessory for industrial control panels, switchgear and automation systems.
Dedicated test sockets provide engineers with an accessible point for measurement and diagnostics without requiring permanent conductors to be removed from a terminal block. This helps simplify commissioning, fault finding and routine maintenance while preserving the integrity and organisation of the installed panel wiring.
The AL2-H8.5-M2.6 is designed specifically for compatible Entrelec SNA terminal blocks and screws directly into the tapped connector-bar hole. When paired with a compatible 2 mm test plug, it creates a compact and reusable test interface suitable for multimeter leads and other appropriately configured electrical test equipment.
