Optical sensors use light to measure physical properties such as position, angle and distance. When light is blocked or interrupted, an electrical signal is generated to indicate a change in the sensor’s environment. Photointerrupters are one type of optical sensor and use an infrared light source, such as an LED, and a phototransistor detector to detect objects and measure changes in the light’s intensity. Photointerrupters can be classified into two categories: slot type and reflective type. OPB390P55 is a photointerrupter of the slot type.

OPB390P55 is an Infrared Coupling Photo Slot Interrupter which consists of an infrared LED and a photo transistor enclosed in a plastic package. The device is designed to be mounted in a slot in a panel, with one side facing inwards. When an object passes through the slot, the detection light will be blocked, the signal will be changed and the output transistor will switch from “off” to “on”. The response time of the OPB390P55 is 2ms maximum, making it ideal for applications that require fast response such as presence detection, material or object classification, security systems and machine safety.

OPB390P55 has a wide range of application fields. It is commonly used in many industrial applications such as paper processing, traffic and access control, material handling, robotics, and medical equipment. In addition, it is also very useful for laboratory and hobby applications such as critical thickness measurement or counting. The sensing range of this photointerrupter is 8 mm, and the slot width is 1 mm, making it suitable for applications where a small object needs to be detected.

In terms of its working principle, OPB390P55 has two main components, an infrared LED and a photo transistor. The LED emits infrared light which exits through the center slot in the package. When an object passes through the slot, the light is blocked and the photo transistor goes from a “cutoff” to an “on” state. When the object moves away from the device, the LED’s light is no longer blocked and the photo transistor returns to the “cutoff” state. The device also contains a built-in hysteresis circuit to ensure a clean on/off signal.

In summary, OPB390P55 is a slot-type photointerrupter which consists of an infrared LED and a photo transistor and uses an object passing through a slot to detect changes in the light’s intensity. It has a wide range of application fields due to its versatility and fast response time. It is mostly used in industrial, hobby and laboratory applications. Its working principle involves the infrared LED emitting light and a photo transistor detecting changes in the light’s intensity once an object passes through the slot. Thanks to its hysteresis circuit, the device is able to generate a clean on/off signal.
