Optical Sensors are photoelectric switch sensors used to detect the presence of an object. They typically consist of an emitting diode and a light detecting element, such as a photodiode or phototransistor. When the object passes between the diode and the detector, or interrupts the light beam, a signal is generated to indicate the presence of the object.

Photointerrupters are a type of optical sensor that uses light interruption technology to detect the presence of an object. Slot type optical sensors use a beam of light emitted from one side of a slot or gap in a device and an optical detector on the other side. As the object passes between the opening, the beam of light is interrupted and a signal is generated.

The GP-A8S is a space saving slot type, logic output photointerrupter designed for use in safety circuits. The lightweight unit is rated to IP67 protection class and features an operating distance of up to 10mm. The unit is highly durable and is resistant to water, chemicals, dust and other environmental hazards.

The GP-A8S is suitable for a variety of applications in consumer, automotive and industrial applications. It provides precise sensing performance in applications such as safety wiring, printing equipment, motor sensors, gaming machines and conveyor belts. The unit is also capable of detecting objects such as metal rods, sheets, tapes and wires.

The working principle of GP-A8S is based on the interruption of light from the emitting diode to the optical detector. The emitting diode is an IR LED and the optical detector is a PIN photodiode. Light from the IR LED is shot at the photodiode, and when an object passes between the two, the light is intercepted and a signal is generated. When the light from the diode is uninterrupted, the signal is LOW and when the light is interrupted, the signal is HIGH.

The GP-A8S features a fast response time of 2ms and a wide operating voltage of 5-24V. It is also extremely reliable, with a mechanical life of over 2 million cycles and an electrical life of over 500K cycles. The unit is also equipped with short circuit protection and anti-noise functions to ensure reliable operation in harsh conditions.

The GP-A8S is a reliable and cost-effective solution for safety and sensing applications in a variety of industries. With its compact size and durable construction, it is suitable for use in a wide range of applications where precise sensing performance is required.
