TE Connectivity DR1/5.ADO 1SNA399491R2500 is a compact 5 mm ADO feed-through miniblock terminal block rated at 13.5 A and 1000 V IEC for conductors up to 1 mm² in industrial control and automation applications.
Why Choose the TE Connectivity DR1/5.ADO 1SNA399491R2500 Feed-Through Terminal Block?
The TE Connectivity DR1/5.ADO 1SNA399491R2500 is a compact ADO insulation displacement feed-through terminal block designed for space-restricted industrial control and automation applications. Part of the established TE Connectivity Entrelec ADO System, this miniblock provides fast conductor termination without conventional screw-clamp wiring while maintaining a reliable electrical connection.
With a rated cross-section of 1 mm², an IEC rated current of 13.5 A and an IEC rated voltage of 1000 V, the DR1/5.ADO delivers useful electrical performance from a terminal only 5 mm wide. The ADO connection system accepts both rigid and flexible conductors and supports up to two wires per connection.
The 1SNA399491R2500 is specifically intended for applications where installation space is limited and dependable connections are required under demanding industrial conditions. Its compact polyamide housing, IP20 main-terminal protection and TH15 DIN rail mounting make it particularly suitable for control panels, machine wiring and automation equipment.
Key Advantages
Compact 5 mm wide miniblock for space-restricted control panels.
13.5 A IEC rated current with a 1 mm² rated cross-section.
Compact ADO Connections for Space-Restricted Control Panels
Miniblock terminal blocks are particularly useful where conventional terminal dimensions would consume excessive DIN rail space. At only 5 mm wide, the DR1/5.ADO allows high-density feed-through wiring while providing a rated current of 13.5 A and accommodating conductors up to 1 mm².
The Entrelec ADO System uses insulation displacement connection technology to simplify conductor termination while providing connections suited to demanding control environments. With support for up to two wires per connection and resistance to the challenging conditions encountered in industrial equipment, the DR1/5.ADO is well suited to compact automation, machine-building and control-panel applications.
Typical Applications
Compact industrial control panels.
PLC and automation systems.
Machine building and OEM equipment.
Instrumentation and control wiring.
Process control installations.
High-density electrical panel wiring.
