OPB390N51

Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The OPB303N51 is an optical sensor developed specifically to detect the presence of objects or reflectors. It is an ideal choice for applications in automation control or industrial equipment requiring precision movements. It is also a preferred option when considering applications requiring higher speed than mechanical devices can provide.

The OPB303N51 is a slot-type optical interrupter with a bipolar transistor output. It consists of an LED and a photo detector, which are connected by a slot. When an object or reflector passes through the slot, light from the LED is blocked, causing a state change in the output.

The sensor has a high sensitivity, meaning that objects or reflectors are recognized quickly. The response speed of the OPB303N51 is up to 1kHz, allowing it to detect even fast-moving objects or reflectors. Also, since the sensor has excellent noise rejection ability, it can be used in environments where there is high levels of electronic noise.

The OPB303N51 has a variety of applications, such as detecting the position of machine parts, paper passing in a printer or copier, and measuring the speed of objects. It is also frequently used in banking and retail applications, as well as for motor defect monitoring in various industrial machines.

The OPB303N51 is a versatile optical sensor that is designed to make monitoring and control processes faster and more accurate. It is simple to integrate into existing equipment, and it can be used in a variety of applications where accuracy and speed are required.
