Aotoro EK51-D50M4 Photoelectric Sensor 50cm Diffuse Reflective AC/DC 24V IP66 Rated

Light ON mode means the sensor's output is active (ON) when it detects the reflected light beam from a target within range. Dark ON mode means the output is active when the beam is absent or blocked. The mode is selected via an internal DIP switch, allowing you to match the sensor's logic to your control system's requirements, such as providing a normally-open or normally-closed signal.

Yes. The EK51-D50M4 is designed for direct compatibility with standard industrial 24V DC power supplies commonly used for PLCs and controllers. Its wide input range (24-240V AC/DC) also allows it to be connected to higher AC voltages without an external power converter, simplifying wiring in panels with mixed voltage sources.

An IP66 rating indicates the sensor is completely dust-tight (6) and protected against powerful water jets (6). This allows for installation in harsh industrial environments subject to dust, debris, and high-pressure washdowns. It is suitable for outdoor use and wet areas, but it is not submersible for prolonged periods.

This sensor can detect a wide variety of surfaces, but detection range can be affected by color, texture, and reflectivity. Light-colored, matte surfaces provide the most consistent 50cm range. For dark, absorbent, or glossy surfaces, the effective sensing distance may be reduced. For optimal performance, refer to the datasheet for specific material response curves and consider testing in the actual application.
