PM U-Shaped Micro Photoelectric Sensors Panasonic Industrial Automation PM U-Shaped Micro Photoelectric Sensors feature a compact body equipped with three protection circuits to minimize the possibility of sensor malfunctions caused by erroneous wiring. The protection circuits include reverse supply polarity, reverse output polarity, and output short-circuit. The PM sensors offer ample beam emitting with a receiving distance of 6mm, beam marks for easy adjustments, and a built-in amplifier. The large operation indicator is easy to view from multiple angles and lights up orange when the beam enters. Panasonic Industrial Automation PM U-Shaped Micro Photoelectric Sensors are easy to mount with M2/M3 screws, resist vibrations and impacts, and are available in an IP64 option. Applications include pallet positioning, sensing the starting point and overrun of a moving body, and sensing the starting point on a rotating body.
