For years, the Cutler‑Hammer® 20 Series has set industry standards for rugged construction and long range optical performance. These Heavy‑duty sensors from Eaton's electrical business are designed for use in harsh environments with constant exposure to weather and physical abuse. Large optics provide exceptional sensing ranges including 700 feet (213 meters) for thru‑beam, 75 feet (23 meters) for reflex, and 8 feet (2.4 meters) for diffuse reflective. Optional logic modules provide integral control functions like time delay, one‑shot output, and stopped motion detection. A totalizer module and LED display cover are available to count passing targets. Choose from a variety of output devices including a 10 amp DPDT relay. All modules are completely enclosed within the rugged aluminum enclosure for protection.
