SH Series, Photointerrupters - Slot Type - Logic Output

The logic output, slot type photointerrupter family consists of devices that utilize a light source and a corresponding photodetector in an opposed-facing alignment. These devices are designed to detect the presence or absence of an opaque object or material positioned between the emitter and receiver. In contrast to transistor output devices of the same name, these photointerrupters incorporate additional receive-side processing that enables them to make binary (two-state) determinations of whether an object is present or not. This added processing simplifies the application of these devices but reduces their flexibility compared to the transistor output counterparts. The photointerrupters are typically used in applications where it is necessary to detect the presence or absence of an object or material that passes through a specific point in a production line. They can be found in various industrial settings, such as conveyor systems, automated assembly lines, and printing presses. The devices are available in a slot-type form factor, with the emitter and receiver components housed in a single unit. The slots are generally narrow, allowing for precise detection of small objects. The photointerrupters come with different specifications, including sensing range, operating voltage, and output type. Overall, the logic output, slot type photointerrupter family provides a simple and cost-effective solution for detecting the presence or absence of opaque materials or objects in industrial applications. Their design allows for easy integration into automated systems, providing reliable and consistent operation.
