The TE Connectivity D2.5/5.C4.L, part number 1SNA290354R1100, is a compact spring-clamp sensor/actuator terminal block designed for high-density industrial control and automation wiring. Part of the Entrelec SNA spring terminal block range, it combines multiple connection levels within a narrow 5 mm pitch, helping reduce valuable DIN rail space inside electrical control panels.
Designed specifically for sensor and actuator connections, the D2.5/5.C4.L uses reliable spring-clamp technology with front wiring access. Spring clamping provides consistent contact pressure independently of the installer and automatically compensates for conductor creep, supporting dependable electrical connections in demanding industrial environments.
With an IEC rated current of 17.5 A, rated voltage of 300 V and conductor capacity from 0.14–1.5 mm² under the manufacturer's IEC spring-clamp data, this grey terminal block provides a space-efficient connection solution for automation equipment. It mounts on TH 35-7.5 or TH 35-15 DIN rail and has an IP20 protection rating.
Sensor and actuator terminal blocks simplify the connection of field devices to control systems by organising multiple conductors within a compact DIN rail assembly. The multi-level construction of the D2.5/5.C4.L enables several circuit connections to be accommodated within only 5 mm of rail width, making it particularly useful where panel space is limited.
Its spring-clamp connection system maintains consistent conductor contact pressure while front-entry wiring improves accessibility during installation. These characteristics make the D2.5/5.C4.L well suited to PLC interfaces, machine controls and distributed sensor and actuator wiring in industrial automation systems.
