					Proximity Sensors,  are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects.
				 
					  |  | 
					Photomicro Sensors These Optical Sensors provide a compact, low-cost method to detect workpieces.

					Rotary Encoders  measure the number of rotations, the rotational angle, and the rotational position.
				 
					  |  | 
					Ultrasonic Sensors  Ultrasonic waves are used to enable stable detection of transparent objects, such as transparent films, glass bottles, plastic bottles, and plate glass, using Through-beam or Reflective Sensors.
