Carlo Gavazzi's PMT series are through beam photoelectric sensors with an effective range up to 65.62 feet. The modulated infrared beam makes them immune to ambient light and provides precise detection. Other features include LED indication, selectable output function, and an IP 67 protection factor. Models feature Screw terminals, and a choice of two different cable gland connections. Timer options include delay on operate, delay on release, and one shot (triggered on leading or trailing edge).
