OPB471L11

The OPB471L11 Optical Sensor is a Slot Type Photointerrupter with a Logic Output. This type of sensor is used in industrial applications to detect a presence or absence of an object passing through a slot. It is primarily used for position and speed sensing, as well as for sensing interruptions in a light source.

The OPB471L11 consists of an infra-red light emitting diode (LED) and a slotted photodetector, mounted inside an insulating package. The sensor has two components, the emitter and the detector, which are optically coupled and arranged in such a way that the path of the light is interrupted when an object moves past it. The interruption of light is detected by the photodetector, which converts the change in light into an electrical signal.

The OPB471L11 works on the principle of detection using an infra-red light source. The light beam is directed to the slotted photodetector, where it is interrupted when an object moves through the slot, generating a change in the electrical signal resulting in either a high (H) or low (L) output. This type of output is known as a logic level output.

The OPB471L11 is typically used in robotic arm applications, as well as conveyor systems and factory automation devices. The sensor is designed to detect objects passing through a slot and provide a signal that can be used to control the movement of the object, as well as the speed and direction of the machine. It can also be used to monitor objects’ position and count objects that pass through the slot. Furthermore, the OPB471L11 can be used to detect interruptions in the light beam, which can indicate the presence of an object in the beam.

The OPB471L11 is a reliable and cost-effective sensing solution that offers fast response times and a low power consumption. The sensor is also designed to withstand high temperatures (up to 105°C) and wide operating voltage range (4.5 – 24V). The OPB471L11 is available in a small, compact package and can be easily integrated into existing applications, making it an ideal choice for industrial use.
