Why Choose the TE Connectivity D2.5/7.ADO-CPE.NF1 Pluggable Railway Terminal Block?

The TE Connectivity 1SNA400156R0200, identified as D2.5/7.ADO-CPE.NF1, is a beige pluggable feed-through terminal block designed for railway and rolling-stock electrical applications. Combining TE Connectivity's ADO System insulation displacement technology with a pluggable connection, it supports efficient pre-wiring and plug-and-play assembly in control and distribution systems.

The terminal is designed for rolling-stock installations exposed to demanding conditions including vibration and mechanical shock. Its ADO connection supports compatible flexible railway conductors without ferrules, while the pluggable architecture enables harnesses to be prepared separately before final installation, helping reduce assembly time during vehicle production and maintenance.

With a 7.62 mm spacing, 2.5 mm² wire-size rating, IEC current rating of 24 A and operating voltage of 500 V AC, the D2.5/7.ADO-CPE.NF1 provides a compact and dependable interface for railway electrical systems. Its polyamide housing, IP20 protection and compatibility with standard 35 mm DIN rails support professional integration into rolling-stock equipment.

Reliable Pluggable Connections for Railway Wiring

The D2.5/7.ADO-CPE.NF1 is designed to increase wiring productivity by combining the TE Connectivity ADO System with a pluggable terminal architecture. Wiring harnesses can be prepared separately and connected during final assembly, reducing the amount of conductor termination required directly inside rolling-stock cabinets and helping streamline vehicle production.

Its design is intended for railway installations exposed to vibration, shock and demanding service conditions. With a 24 A IEC current rating, 500 V rated voltage, 180 A for 1 s short-time withstand capability and an operating temperature range from -55 to +110 °C, it provides a robust connection solution for professional rolling-stock electrical systems.

Typical Applications

• Railway rolling-stock electrical systems.
• Pre-wired train electrical harnesses.
• Rail vehicle control and auxiliary panels.
• On-board automation and signalling equipment.
• Pluggable control and distribution circuits.
• Railway equipment cabinets exposed to vibration and mechanical shock.
