Why Choose the TE Connectivity D1.5/6.SNT2.ADO Disconnect Terminal Block?
The TE Connectivity D1.5/6.SNT2.ADO (1SNA199144R2000) is a compact ADO knife-disconnect terminal block with two integrated test sockets, designed for control, measurement and automation circuits where convenient isolation and testing are required. Part of the established TE Connectivity ENTRELEC SNA ADO range, it combines circuit-disconnect functionality with ADO insulation-displacement connections on both sides.
A manually operated disconnect knife blade allows the electrical path to be opened directly at the terminal without removing conductors. Two integrated 2 mm test sockets provide convenient measurement access during commissioning, diagnostics and maintenance, making the D1.5/6.SNT2.ADO particularly useful in circuits that need to be tested or isolated individually.
The terminal has a rated cross-section of 1.5 mm², accepts fine-stranded conductors from 0.34–1.5 mm², and is rated at 10 A and 500 V. Its narrow 6 mm width, grey polyamide housing, IP20 main-terminal protection and TH35 DIN rail compatibility make it a space-efficient solution for professional industrial terminal assemblies.

Reliable Circuit Isolation and Testing with ADO Connections
Disconnect terminals allow individual electrical circuits to be opened without removing their conductors from the terminal strip. The D1.5/6.SNT2.ADO incorporates a hand-operated knife blade that provides a straightforward mechanical disconnect point, supporting commissioning, fault-finding and maintenance procedures where controlled circuit isolation is required.
The terminal also incorporates two 2 mm test sockets for convenient measurement access. Combined with ADO insulation-displacement termination on both sides, a compact 6 mm footprint and TH35 DIN rail mounting, this makes the 1SNA199144R2000 particularly suitable for densely populated control and instrumentation terminal assemblies.
Typical Applications
- Industrial electrical control panels.
- PLC and automation cabinets.
- Measurement and instrumentation circuits.
- Process control systems.
- Machine control and auxiliary circuits.
- Circuits requiring individual isolation and testing.
- Commissioning and diagnostic terminal assemblies.
- OEM machinery and industrial panel building.
