1sna146202r0500 – dr4/6,ado,ex

Why Choose the TE Connectivity DR4/6.ADO.EX 1SNA146202R0500 Miniblock Terminal Block?

The TE Connectivity DR4/6.ADO.EX 1SNA146202R0500 is a light-grey ADO insulation-displacement miniblock terminal block designed for compact industrial wiring and control-panel applications. Part of the established Entrelec ADO terminal range, it combines a particularly small footprint with direct insulation-displacement connection technology for efficient conductor termination.

The DR4/6.ADO.EX has a compact 6 mm spacing and measures approximately 31 × 6 × 18.5 mm. Its miniblock format makes it especially useful where installation space is restricted and conventional full-size DIN rail terminal blocks would occupy unnecessary panel area.

Manufactured with a durable polyamide insulating body, the terminal is designed for mounting on a TH15-5.5 miniature DIN rail in accordance with IEC 60715. It is specified for operation from -55 to +110 °C and belongs to the manufacturer's ADO.Ex range for appropriately engineered industrial and hazardous-area equipment assemblies.

Reliable ADO Connections in a Compact Miniblock Format

The Entrelec ADO connection system uses insulation-displacement technology to provide efficient conductor termination without relying on a conventional screw-clamp connection. This connection principle is well suited to repetitive industrial wiring where compact construction, consistent termination and efficient assembly are important.

At only 31 mm high, 6 mm wide and 18.5 mm deep, the DR4/6.ADO.EX provides a highly compact connection solution for miniature terminal assemblies. Its TH15 rail compatibility, polyamide construction and broad temperature capability make it suitable for professional industrial equipment where both installation density and dependable connectivity are priorities.

Typical Applications

• Compact industrial electrical control panels.
• Machine building and OEM equipment.
• Factory automation systems.
• Signal and control circuit termination.
• Miniature DIN rail terminal assemblies.
• Industrial equipment using compatible ADO.Ex terminal components.
