Photoelectric retro-reflective sensor | 5000mm | 88x65x25mm | 24-240VAC/12-240VDC | ABS | infrared LED beam | IP67
Code: PTL-DM5SKT3-DPhotoelectric sensor operating on the retro-reflective principle, where infrared light is reflected from a reflector and returns to the sensor. Ensures easy installation, accurate object detection, and high resistance to external interference.
Thanks to IP67 protection, a wide voltage range, and a durable PC/ABS housing, the sensor is ideal for both industrial equipment and home automation systems.
