Optical sensors can be categorized into various types depending on factors such as photo source, detector type, receiving signal type, and area of sensitivity. Photointerrupters are among the most widely used types of optical sensors, which send and receive infrared signals between light-emitting and light-receiving elements. They can be further classified into various types based on the shape of the beam emitted, such as slot type, reflective type, fork type, and through-beam type. Depending on the signal output, photointerrupters can be divided into switches that provide true/false outputs and logic output type that provide digital signal outputs.

The GP-XC12ML-P is a logic output photointerrupter belonging to the slot type family. It features a compact, leadless shape comprising of an infrared LED and a phototransistor, coupled by a compact slot. This slot has a 12 millimeter pitch distance and is able to provide a resolution ranging from 0.5mm to 0.4mm. Due to their compact size, the GP-XC12ML-P optical sensors are suitable for use in limited-space settings. As a logic output type, the photointerrupter produces a digital signal output of either low (0V) or high (5V) when an object passes through the slot.

The GP-XC12ML-P optical sensor is well-suited for use in various applications, such as position and speed detection gauges, paper and ticket transport mechanisms, warning mechanisms, and various other automation equipment. It is able to sense a range of objects from round to flat and shiny to non-shiny. The analog variations of the signal received are also converted into digital signals which provide more accurate data that are not affected by the temperatures or external noise.

The GP-XC12ML-P optical sensor works on the basis of amount of light received by the phototransistor and the reference voltage set on the LED. When an object passes through the slot, the sensing procedure begins. The LED emits infrared radiation which gets intercepted by passing objects. The amount of light received by the phototransistor is then measured and the signal is converted into a digital output that is low (0V) or high (5V). Furthermore, a variation setting is provided on the LED, which helps to attenuate the signal response time of the phototransistor when the object speed changes.

Overall, the GP-XC12ML-P logical output photointerrupter is an effective and reliable solution for automating various processes such as position and speed detection, paper transport, and ticket transport. Through its compact design, it can be installed in limited-space settings to provide accurate digital output signals. To prevent noise interference, the signals can be outputted in a logic type, which removes any analog variations. The LED is also fitted with a variation setting, which helps to adjust the signal response time when the object speed changes.
