Why Choose the TE Connectivity AL3 Test Socket?
The TE Connectivity AL3, manufacturer part number 1SNA163261R0000, is a compact 3 mm terminal block test socket designed for use with compatible ENTRELEC SNA terminal blocks. This conducting accessory provides a dedicated test point for electrical measurement, commissioning and maintenance without requiring the main field wiring to be disconnected.
The AL3 provides a 3 mm diameter test socket and is designed to integrate directly with compatible terminal blocks in the ENTRELEC SNA system. It enables technicians to establish an accessible measurement point within a terminal assembly, helping simplify voltage checks, diagnostics and fault finding in industrial control and distribution equipment.
With an individual weight of approximately 1.2 g, the AL3 is a small and practical panel accessory that adds test functionality without significantly increasing the size of the terminal assembly. It is supplied in packs of 50 pieces, making it suitable for panel builders, machine manufacturers and maintenance departments installing multiple test points.
