The GP1S525V is a slot-type photointerrupter with a transistor output, typically used in applications such as automation sensors, conveyor belt turbines, printing machines, key switches, computer peripherals, communication equipment, office apparatus, consumer products, and various detection and sensing applications. The GP1S525V features an optically isolating slot-type exhibiting excellent on-off characteristics in combination with a transistor output. This photointerrupter includes an emitter, detector, and collector integrated in a single package. The emitter type is an infrared light emitting diode used to detect an opaque, reflective, or transparent object. The detector type is an NPN silicon photo transistor coupled to the emitter. The collector/output pin is low impedance and is triggered when the object passes between the emitter and detector.

The working principle of the GP1S525V is simple. When the emitter LED of the GP1S525V is coupled with the detector transistor, their optical axis is aligned to the interrupter slot, creating an infrared beam which passes through the slot. When the slot is interrupted by an opaque, reflective, or transparent object, the infrared beam is blocked, causing the detector transistor to switch to a conductive on-state. This provides a low impedance collector (output) from which one can extract a signal indicating the presence of an object. When the object is removed, the transistor remains active and the output is kept at a low level.

The GP1S525V\'s excellent characteristics and excellent interchangeability make it ideal for a variety of applications. The photointerrupter can detect objects with a width as small as 0.6mm, and an operating distance up to 4mm is possible depending on the object\'s width and reflective properties. The GP1S525V also operates over a wide temperature range of -40°C to +85°C and offers a number of safety features including reverse polarity protection and over-current protection. Furthermore, the GP1S525V has a low total emission of only 0.2 nW.

The GP1S525V is designed to offer superior performance and reliability in challenging applications. Its potential and demonstrated value have made it a popular choice among engineers and designers. The GP1S525V has been successfully used in automated processing lines, industrial machinery, home appliances, and a host of other applications. Additionally, the GP1S525V\'s low cost and wide availability have made it a cost-effective alternative for a variety of applications.
