1sna206723r0300 – al4-m4 test socket [pk=50]

Why Choose the TE Connectivity 1SNA206723R0300 AL4-M4 Test Socket?

The TE Connectivity 1SNA206723R0300, designated AL4-M4, is a 4 mm test socket from the ENTRELEC SNA terminal-block accessory range. It provides a dedicated electrical test point on compatible terminal blocks, enabling technicians to connect suitable test equipment for commissioning, measurement, diagnostics and maintenance without disturbing the main conductor connections.

The AL4-M4 is designed to screw directly into the tapped hole of the terminal block connector bar and accepts compatible FC-series test plugs. It features a 4 mm internal socket diameter, an M4 screw mounting arrangement and a nominal height of 13.5 mm, providing a secure and readily accessible test interface within the terminal assembly.

With compact nominal body dimensions of approximately 5 × 5 × 12.5 mm and a net weight of approximately 1.3 g, the 1SNA206723R0300 adds convenient test access with minimal impact on panel space. It is specified for compatible ENTRELEC terminals including M10/10.RS and M35/16 and is supplied in packs of 50 pieces.
