Photo interrupter, photogate, photodiode, phototransistor, whatever you want to call it, this sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications including optical limit switches, pellet dispensing, general object detection, etc. Gap width = 10mm
Photo Reflectors are designed on dust-proof, light modulation, UV light source. Unique Sensors also have special wavelength light source and lens technology such as spot and bar light.
Interrupter-separate type can encompass 100-2000mm detecting distance and can be mounted by various ways.As the measurement of ambient light, light modulation sensors are available.
This sensor is categorized in Photo Reflector but this unique sensor combined with prism can sense the object stably. Wiring is not necessary on prism side.We detect objects by combining the prism with the photo sensor , because the light guide path is set, it enables stable light sensing.
This photo sensor combined Photo Interrupter with actuator which can make it possible to sense stably by changing lever length and shape regardless of detecting object.
Light emitting diodes (LEDs) :LEDs are semiconductor light sources. The light emitted from LEDs varies from visible to infrared and ultraviolet regions. They operate on low voltage and power. LEDs are one of the most common electronic components and are mostly used as indicators in circuits. They are also used for luminance and optoelectronic applications.
Photo Transistor: A phototransistor is a light-sensitive transistor. A common type of phototransistor, called a photobipolar transistor, is in essence a bipolar transistor encased in a transparent case so that light can reach the base–collector junction.
Photodiode: A Photodiode is a semiconductor device that converts light into an electrical current. The current is generated when photons are absorbed in the photodiode. Photodiodes may contain optical filters, built-in lenses, and may have large or small surface areas.
A photoelectric sensor, or photo eye, is equipment used to discover the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver.
