Cutler‑Hammer® 55 Series photoelectric sensors are identical to Eaton's 50 Series except without the interchangeable outputs or logic functions. They offer durability and high optical performance in a cost‑effective, self‑contained package. The 55 Series features sensors with AC and DC operation in a single unit. A relay option is available on these models that provides a 3 amp SPDT relay output for high current switching. Sensors are available in thru‑beam, reflex, polarized reflex, diffuse reflective and fiber optic sensing modes. Each sensor features a built‑in swivel bracket for easy mounting and to allow precise adjustment of the sensor alignment.
