1sna399689r1300 – d1/5,c3,ado

Why Choose the TE Connectivity D1/5.C3.ADO 1SNA399689R1300 Sensor Terminal Block?

The TE Connectivity D1/5.C3.ADO 1SNA399689R1300 is a compact three-level sensor terminal block with ADO insulation-displacement connections, designed for efficient connection of three-wire sensors in industrial automation and control systems. Part of the established Entrelec ADO terminal block range, it combines high wiring density with fast, reliable conductor termination.

Designed specifically for three-wire sensor applications, the D1/5.C3.ADO provides three connection levels within a narrow 5 mm spacing. Its ADO System connection technology accepts rigid conductors from 0.2–1 mm² and flexible conductors from 0.22–1 mm², while the upper deck can accommodate up to two wires for additional wiring flexibility.

The terminal is rated at 13.5 A and 250 V under IEC specifications, with an 8 kV impulse withstand voltage and 120 A short-time withstand current for 1 s. Its compact grey polyamide housing mounts on standard TH 35 DIN rails and is designed for demanding control environments where vibration, shock and corrosion resistance are important.
