Optical Sensors, also known as optical encoding sensors or detectors, are devices that detect the existence of an object by means of its reflection or scanning of visible, near-infrared or infrared light in the form of a narrow beam. Among optical sensors are Photointerrupters, Slot Type and Transistor Output. The OPS665 is an optical sensor specifically designed for reading small or low contrast bar codes or labels. It is commonly used in medical, auto-ID and industrial automation applications.

OPS665 Photointerrupters are sensors that have a slot type configuration with transistor outputs. It utilizes two phototransistors in close proximity within the housing designed to differentiate the presence or absence of an object as it passes across the sensing zone of the sensor. When an object is present in the sensing zone, the light emitted by the LED source is blocked from reaching the phototransistor, resulting in the output signal becoming inactive. When the object no longer obstructs the light, the output signal becomes active.

By utilizing a slit configuration and two phototransistors, the OPS665 can provide superior accuracy and performance compared to other optical sensors. The light output of the LED is arranged so that it offers excellent light concentration within the sensing zone. This ensures that any external light interference is eliminated for reliable operation. The large gap between phototransistors allows for higher light transmission levels for improved scanning performance.

The OPS665 Photointerrupters are designed for durability and can withstand intense applications. The housing is constructed of high-quality polycarbonate, offering excellent insulation from dust, dirt, oil and other environmental contaminants and providing excellent resistance to shock and vibration. It also features an IP67 protection rating for use in wet or oily conditions. The OPS665 Photointerrupters are designed to operate in temperatures of -20°C to +85°C and are capable of detecting objects moving at speeds up to 25 m/s.

These Photointerrupters are an ideal choice for applications requiring accurate and reliable detection of metallic or non-metallic objects. They are ideally suited for fast and accurate detection of small labels or objects, making them an excellent choice for applications such as shipping and inventory management, product code verification, and barcode scanning. With their ability to accurately detect different objects, these Photointerrupters are becoming increasingly popular in medical, auto-ID and industrial automation applications.
