1sna206722r0200 – al4-m3-r1 test socket

Why Choose the TE Connectivity 1SNA206722R0200 AL4-M3-R1 Test Socket?

The TE Connectivity 1SNA206722R0200, designated AL4-M3-R1, is a 4 mm test socket from the ENTRELEC SNA terminal-block accessory range. It provides a dedicated test connection point for compatible terminal blocks, allowing technicians to connect suitable test equipment without disturbing the main field wiring.

The AL4-M3-R1 is screwed into the tapped test hole of the terminal block connector bar, providing a secure and accessible interface for electrical measurement, commissioning and fault-finding. Its 4 mm socket diameter makes it suitable for compatible test-plug connections used in professional industrial electrical installations.

With compact nominal dimensions of 5 × 5 × 12.5 mm and a net weight of approximately 1.62 g, the 1SNA206722R0200 adds test access with minimal impact on terminal assembly size. It is specified for compatible ENTRELEC terminals including 131ETTM4TM4, 165ETTM5TM5, 165LTTM5TM5 and M6/8.RS.
