Why Choose the TE Connectivity 1SNA199276R0400 DR4/6.ADO Orange Miniblock Terminal?
The TE Connectivity 1SNA199276R0400, type DR4/6.ADO, is a compact feed-through miniblock terminal from the Entrelec SNA ADO range. This specific variant is identified as orange and combines a conventional screw-clamp connection with the Entrelec ADO System, providing a practical interface for industrial control, automation and equipment wiring.
Designed around a 1.5 mm² rated cross-section, the DR4/6.ADO uses a compact 6 mm spacing and single-level construction. Its reduced dimensions of approximately 31 mm high × 18.5 mm deep make it particularly useful where terminal space is restricted and a smaller rail format is preferred.
Unlike standard 35 mm DIN rail terminals, the 1SNA199276R0400 is designed for installation on a TH15-5.5 15 × 5.5 mm mounting rail in accordance with IEC 60715. With an 8 kV rated impulse withstand voltage, UL 94 V-0 flammability classification and hybrid screw/ADO connectivity, it provides a space-efficient connection solution for compact industrial electrical assemblies.

Compact ADO Connectivity for Miniature Rail Systems
The DR4/6.ADO is designed specifically for compact terminal installations where conventional full-size DIN rail terminals may occupy unnecessary space. Its 31 mm height, 18.5 mm depth and TH15-5.5 mounting format allow designers to create smaller connection assemblies while retaining the modularity of a rail-mounted terminal system.
Hybrid screw-clamp and ADO connectivity allows conventional screw-terminated wiring to interface with the Entrelec ADO System within a single feed-through terminal. The 9.5 mm stripping length, specified tightening torque and 1.5 mm² rated cross-section provide defined installation parameters, while the orange housing helps distinguish the terminal from other DR4/6.ADO variants within colour-coded wiring schemes.
Typical Applications
- Compact industrial control panels.
- Miniature terminal rail assemblies.
- PLC and automation equipment.
- Machine control wiring.
- Signal and auxiliary circuits.
- ADO-to-screw wiring interfaces.
- OEM electrical and electronic equipment.
- Colour-coded control wiring systems.
