Allen-Bradley 855T-B10TL6 Blue LED Stack Light 70mm

The Allen-Bradley 855T-B10TL6 Blue LED Stack Light is a 70 mm Control Tower stack-light module with a blue lens and black housing, designed to operate from 120 V AC (±10%) at 60 Hz for continuous status indication in industrial automation. This steady LED module provides constant blue illumination and is intended to be used with 70 mm stack-light bases to form a signaling tower for machines, conveyors, and robotics in harsh environments, with IP65 protection (NEMA 4X) and a polycarbonate construction. Key specifications include outer diameter 70 mm; recommended wire size 0.5 mm²; recommended terminal torque 0.8 Nm; rated operating voltage 120 V AC; leakage current tolerance up to 3 mA from solid-state outputs without module activation; operating temperature −25 °C and storage temperature −40 °C; lens color Blue; housing color Black; and a Steady LED module type for continuous light. The 855T family supports 5-module stacks with shock up to 35 G on surface-mount bases or 10 cm aluminum pole bases, and vibration around 0.75 G, making it suitable for industrial signaling on equipment where a bright, unambiguous blue indication is required.
