Retro-reflective mode typically allows longer sensing ranges than diffused mode due to the increased efficiency of the reflector compared with the reflectivity of most targets. All types of sensors can be basically classified into analog sensors and digital sensors. The advantage is that a secondary device, such as a reflector or a separate receiver, is not required. A transducer that works on the principle similar to the sonar or radar and estimate attributes of the target by interpreting is called as ultras… Objects in front of or behind this sensing window are ignored. Mouser offers inventory, pricing, & datasheets for NPN Photoelectric Sensors. This mode is the most efficient of the three, and allows the longest possible sensing ranges for photoelectric sensors. A typical application for passive infrared sensors is controlling automatic doors or lights. Zone scanners – Much like passive infrared sensors, area scanners are used to detect the presence or movement of an object within a defined sensing area or zone. Typical applications for luminescence sensors are detecting the clear tamper-proof seals on medicine bottles or detecting a defective product that has been marked with chalk (i.e. This article is focused on photoelectric sensors and defines what they are, their advantages and some basic modes of operation. This mode also minimizes sensitivity to a target’s color among the diffused mode variations. These sensors are designed for Class I, II, and III; Division 1 and 2, Groups A, B, C, D, E, F, and G hazardous locations. light emitting element) and receiver (e.g. Fiber sensors guide the light from the transmitter through either plastic or glass cables called fiber optic cables. This mode is suited for detecting shrink-wrapped pallets, as a standard retro-reflective mode sensor can mistake the glossy covering for a reflector and not change state. For mechanical background suppression, there are two receiving elements in the photoelectric sensor, one of which receives light from the target and the other receives light from the background. Plastic fiber optic cables are typically more flexible and cost-effective than glass versions, can be cut to length, and work only with visible light.

Color – Color sensors are available in a wide variety of styles and options. This makes the arrays ideal for detecting oddly shaped parts, products with gaps or spaces, or inconsistently positioned targets, at a fraction of the cost of using multiple sensor pairs. Our Bulletin 45LUM Luminescence Sensors detect the presence of luminescent/fluorescent particles and materials which are invisible to the human eye. This is a simple photo switch suitable for home and industrial purposes.The circuit switches on a relay when the light intensity falling on the sensor crosses the set limit. From true RGB color recognition sensors designed for industrial use to sensors to detect registration marks and a wide range of background colors, including difficult pastels, we make color/contrast sensors to meet your applications needs.
