Why Choose the TE Connectivity D2.5/5.C3.L.L 1SNA290352R1700 Sensor/Actuator Terminal Block?

The TE Connectivity 1SNA290352R1700, manufacturer designation D2.5/5.C3.L.L, is a compact three-level spring-clamp sensor/actuator terminal block with an integrated 24 V DC green bidirectional LED. Part of the established TE Connectivity ENTRELEC SNA spring terminal block range, it is specifically designed for efficient connection and status indication of three-wire sensors and actuators in industrial automation systems.

The D2.5/5.C3.L.L combines three connection levels within a space-saving 5 mm pitch, helping maximise wiring density in PLC cabinets, machinery and process-control panels. Its integrated green bidirectional LED provides convenient visual circuit-status indication, while front wiring entry makes conductor installation, inspection and maintenance readily accessible.

With a rated cross-section of 1.5 mm², rated current of 17.5 A and rated voltage of 300 V, the 1SNA290352R1700 provides dependable connectivity for sensor and actuator circuits. Spring-clamp technology maintains consistent contact pressure and automatically compensates for conductor creep, while compatibility with TH35-7.5 and TH35-15 DIN rails enables straightforward integration into standard industrial control cabinets.

Sensor and Actuator Connections with Integrated Status Indication

Three-wire industrial sensors and actuators require multiple connections for signal and power distribution, which can consume considerable DIN rail space when conventional single-level terminals are used. The D2.5/5.C3.L.L addresses this requirement with a three-deck architecture in only 5 mm of panel width, allowing field-device wiring to be organised efficiently within high-density automation cabinets.

The integrated green bidirectional 24 V DC LED provides immediate visual indication of circuit status, making commissioning and troubleshooting easier. Combined with front-entry spring-clamp connections and automatic compensation for conductor creep, the 1SNA290352R1700 provides a practical solution for reliable sensor and actuator connectivity in modern industrial automation systems.

Typical Applications

• Three-wire industrial sensor connections.
• Actuator wiring in 24 V DC automation systems.
• PLC input and output control cabinets.
• Industrial machinery and machine-building applications.
• Process control and instrumentation systems.
• High-density DIN rail wiring with visual circuit-status indication.
