Optical sensors are an important class of sensing devices used in a wide variety of applications. One specific type of optical sensor is a photointerrupter, which contains an emitter and an internal receiver that are separated by an opaque slot. When an object passes through the slot, the emitter’s light is interrupted and the receiver is blocked thus producing an output signal. GPIO1A91LCJ00F is an example of a slot-type photointerrupter with logic output.

GP1A91LCJ00F application field and working principle

The GP1A91LCJ00F photointerrupter consists of an emitter and receiver in a glossy black plastic package. It utilizes near-infrared radiation which is less likely to be affected by visible light, making it suitable for use in high-precision detection of objects with various colors. Additionally, the GP1A91LCJ00F has a 20V rating with 111.7mA maximum operation current, making it suitable for applications requiring high-voltage operation. The GP1A91LCJ00F detects objects in various materials such as paper, plastic, and wood. It is also capable of detecting objects with complex shapes.

The GP1A91LCJ00F features a slot-type structure with logic output, where the emitter and the receiver are separated by an opaque slot. The emitter consists of a near-infrared light-emitting diode, and the receiver consists of a phototransistor. When an object passes through the slot, the emitter’s light is interrupted and the receiver is blocked. This causes the output signal to go low. The GP1A91LCJ00F then swaps the emitter and receiver into the same output, so that the emitter is blocked and the receiver is unblocked. This causes the output signal to go high.

In terms of applications, the GP1A91LCJ00F is suitable for use in automated production lines. It is also applicable for counting objects, measuring length, detecting paper and cardboard, controlling an assembly line system, and other applications that require the precise detection of an object in a given area.

The GP1A91LCJ00F is a small, reliable, and cost-effective device suitable for many different high-precision detection applications. Its slot-type structure and logic output make it an ideal choice for applications requiring a fast and accurate response time. Additionally, the GP1A91LCJ00F can detect objects with varying colors and complex shapes, and is suitable for high-precision detection in production systems.
