A GP1S562 photointerrupter is part of the optical sensors made by Canon, consisting of an infrared light emitting element (emitter) and a light receiving element (receiver) housed in a compact cylindrical package. It is a slot type photointerrupter that detects the presence or absence of objects by interrupting the infrared light emitted from the emitter, and provides a transistor output to specify the conditions.

The GP1S562 photointerrupter features a shielded design and can detect objects through plastic or painted materials. It is suitable for applications where the ambient light is strong, and for applications where high-speed response is needed. It is also compatible with lead-free soldering and can be used in a wide range of applications with its wide range of cathode-side pin packages.

The GP1S562 has a wide operating voltage range of 3 to 24 V, a response time of 2 μs typ., and a supply current of 10mA max. The recommended ambient operating temperature range is 0 to 40°C. It is also insensitive to dust and moisture, making it suitable for use in a variety of environments. The reverse voltage protection feature also ensures correct operation in the event of reversed polarity power supply connections.

The working principle of the GP1S562 is centered around a modulated infrared light emitting diode (LED) and a phototransistor. The LED is driven by a high frequency oscillator and emits a continuous stream of modulated infrared light directed towards the phototransistor. The phototransistor then converts the light signal into an electrical signal, and a comparator then outputs a high or low signal based on the intensity of the light.

The application fields for the GP1S562 include flow meters, sensing paper and board edges, keeping track of objects in a conveyor system, detecting the mark for optical character recognition, sensing windows and slots in equipment, controlling automation machines, and various other industrial applications. It is especially useful for applications where high-speed response and high levels of accuracy are required.

In conclusion, the GP1S562 photointerrupter is an essential component of Canon’s optical sensors. It is versatile, and can be used for applications where fast response and accuracy are needed. It features a shielded design, reverse voltage protection, a wide operating voltage range and a response time of 2 μs typ. The application fields are varied and it is suitable for use in a variety of environments.
