Featuring a built-in amplifier, it simplifies integration into various automation systems without the need for an external controller. This sensor operates on a versatile 5 to 24 VDC power supply and provides a fast NPN open-collector output, with a selectable Light-ON or Dark-ON operation mode to fit specific application needs. Its infrared light source ensures stable detection of small opaque objects. The pre-wired cable with a connector allows for quick and secure installation, while the integrated light indicator provides clear visual feedback of the operational status. Made in Japan, the EE-SPW321 is an ideal solution for precise positioning, presence sensing, and counting applications.
