Industrial 256-455 Photoelectric Sensor Switch

RS 256-455 Photoelectric Sensor Switch with reflector is an industrial, non-contact sensing device that uses a light beam to detect the presence of objects and outputs a PNP signal. It operates on a 10–30 V DC supply and is cataloged with the identifiers 156170 and 0041. The unit includes a reflector to establish the sensing path, enabling straightforward setup in compact installations and diverse layouts. The RS 256-455 designation identifies this sensor within its series, making it easy to source compatible components and replacements. With its PNP output, the sensor is designed for direct interfacing with control inputs and PLCs that expect a positive-true switching signal, aligning with common industrial wiring practices for sensing applications. This configuration supports integration into automation tasks where contact with the target is undesirable, enabling fast response in line with typical factory or process-control environments. The combination of a wide 10–30 V DC range, reflector-enabled sensing, and compact form factor makes the RS 256-455 a suitable option for applications requiring reliable, non-contact object detection alongside a minimal component count.
