OPB668N

Optical Sensors - Photointerrupters - Slot Type - Logic Output

OPB668N optical sensors are photointerrupters of a slot type with a logic output, ideally suited for applications that require low current consumption while sensing motion. The OPB668N has a small PCB footprint (20mm x 5mm) making it applicable to many applications in a variety of different mechanical spaces. Its fast response time (3ms on-time) and high noise suppression (ENO 4000mVMin) make it a popular choice for automated production line equipment, medical equipment, office automation, safety and security devices and industrial applications.

The OPB668N works by using an optical source and an optical detector to detect the interruption of the optical path. The optical source is typically an infrared LED and the detector can either be a phototransistor or photo diode. When any object or material interrupts the optical path, it is detected by the detector, causing the LED to turn off. The logic output will then change state from high (LED on) to low (LED off). This logic output can then be used to trigger an event, control a relay or initiate communication over an industrial data bus.

OPB668N optical sensors are engineered to ensure reliable operation even in harsh industrial and environmental conditions. The robust dust-proof construction and shielded housing improve the performance of the photointerrupter, blocking out dirt and dust that may disrupt its operation. The built-in LED indicator assists in checking the status of the photointerrupter, aiding troubleshooting and helping to identify any potential problems. Since the OPB668N is highly immune to noise (ENO 4000mVMin), it supports easy wiring and reliable operation even in areas with a high level of electromagnetic interference.

The OPB668N is a versatile sensor with a wide range of applications. It can be used to accurately detect the motion of objects, detect the passage of materials, count parts or detect jamming on production lines. Its small size and low current consumption (15mA max) make the OPB668N an ideal choice for applications where space and power consumption are a priority, such as medical equipment and small automation systems. The OPB668N is also suited for applications that require a degree of environmental robustness, such as industrial robots and automated production lines.

In summary, the OPB668N is an opto-electrical photointerrupter with a logic output that is well-suited for use in harsh and compact environments. Its fast response time and high noise suppression make it a popular choice for a wide range of applications, and its robust dust and interference-resistant construction make it reliable and easy to use in high-EMI areas.
