The TE Connectivity D2.5/5.C4.L.L, part number 1SNA290356R1300, is a compact four-level spring-clamp sensor/actuator terminal block designed for high-density industrial automation wiring. Part of the Entrelec SNA spring terminal block range, it provides connections for four-wire sensors within a narrow 5 mm pitch, helping maximise available DIN rail space in control panels and machine cabinets.
This version incorporates a bidirectional green LED for 24 V DC circuits, allowing circuit status to be identified quickly during operation, commissioning and maintenance. Front-entry spring-clamp connections provide convenient conductor access while maintaining consistent contact pressure independently of operator tightening torque.
The D2.5/5.C4.L.L has an IEC rated current of 17.5 A, a rated voltage of 300 V and a rated cross-section of 1.5 mm². Its compact 5 × 95 × 41 mm construction and compatibility with TH 35-7.5 and TH 35-15 DIN rails make it particularly suitable for PLC interfaces, sensor connections and high-density industrial control systems.
Four-level sensor terminal blocks allow power, signal and associated sensor conductors to be organised within a very narrow DIN rail footprint. The D2.5/5.C4.L.L accommodates a four-wire sensor arrangement within only 5 mm of terminal width, making it particularly useful in control panels containing large numbers of field sensors and PLC input circuits.
Its integrated 24 V DC bidirectional green LED provides immediate visual circuit status indication, while the spring-clamp connections compensate automatically for conductor creep and maintain dependable contact pressure. Together, these features simplify installation, troubleshooting and maintenance in industrial automation systems.
