Optical Sensors play an integral role in the electronics industry. Among the many types of optical sensors is the Photointerrupters classification, of which the Slot Type optical sensor falls. The OPB841L51 Photointerrupters is a specifically designed Slot Type optical device which features Transistor Output capabilities. By opting for the OPB841L51, users have access to all the cutting edge features such as optimal on-sensor design, wide operation gap and low-cost construction. The OPB841L51 is best suited for applications such as consumer electronics, industrial safety, industrial automation, medical, data communications, motion/position sensing, and home security.

The OPB841L51 features a substrate construction which is optimized for minimal self-blockage. This ensures that the optical signals are allowed to pass through the substrate between the tip and base of the sensor. The design also lends to high signal integrity and excellent noise immunity that is otherwise not achievable with traditional Photosensor construction. To further optimize the sensitivity of the device, an integrated biasing technique is used, with active filters that help minimize external noise.

The OPB841L51 is powered by a 5V DC input, and features a 2.5mm gap that ensures effective transmission of light. The device has a typical CXT of 10ns and maximum frequency response of up to 2MHz which makes it ideally suited for high speed applications. The device also comes with a variety of outputs which include open collector TTL, NPN-type, and non-inverting / inversion outputs. With the non-inverting output, the user can easily detect the end position of moving objects for position sensing and data collection.

The OPB841L51 Photointerrupters Slot Type optical sensor’s working principle is based on the interruption of the light signal by external objects. The device has an integrated source and detector embedded in the main module. When a light signal is projected through the gap, it is detected by the detector and redirected to the output. When an external object interrupts the light signal, the detector senses and the output is triggered while the LED remains powered on. This ensures that the device has maximum sensitivity even in environments with high background noise or dust absorption.

The OPB841L51 is manufactured with superior quality materials and components and is provided with IPX7 ingress protection. This makes it highly reliable for industrial and hazardous applications. The device is supplied with a 2-wire integrated power-and-output cable for additional convenience and wiring ease. Thus, with its advanced design capabilities and reliability, the OPB841L51 is an ideal choice for many applications.
