Efficient ADO and Screw-Clamp Connection Technology
ADO technology uses an insulation displacement connection method designed to simplify conductor termination while maintaining a secure electrical connection. Combining an ADO connection with a conventional screw clamp gives panel builders flexibility when different conductor termination methods are required within the same terminal row.
The D4/6.ADO.1 combines this hybrid connection arrangement with a compact 6 mm profile, 17.5 A IEC current rating and 1000 V IEC voltage rating. Its single-level feed-through configuration makes it suitable for organised signal, control and automation wiring where DIN rail space and reliable connectivity are important.
Typical Applications
- Industrial electrical control panels.
- Machine control and automation systems.
- Signal and control wiring circuits.
- PLC and instrumentation installations.
- OEM machinery and production equipment.
- High-density DIN rail terminal assemblies.
