Optical sensors are devices that detect and measure light intensity, most commonly used to measure the visible light emitted from a source such as a lamp, LED, or laser diode. Photointerrupters are a type of optical sensor that uses a slit, or slot, to detect objects passing through it. The OPB462P11 is a photointerrupter featuring a logic output, designed for applications such as presence sensing, thickness measurement, and alignment.

The OPB462P11 consists of a pair of gallium arsenide infrared LED and a Positive-Intrinsic-Negative (PIN) Photodiode. The infrared LED is mounted on the PCB, using Leg-Type housing, and emits light into the slot of the photointerrupter. The PIN photodiode is mounted on the same PCB, facing the same slot, and is sensitive to the infrared light. When an object passes through the slot, the light from LED is interrupted, and the voltage generated by the PIN photo diode changes, which is then amplified by an output circuit. This change in voltage is then detected by the output circuit, and a logic output signal is generated with a high or a low level.

The OPB462P11 has a 8mm wide slot with two sensing edges. The slot width is designed to detect objects with a minimum height of 2.5mm, up to a maximum of 10mm. The device includes an on-board emitter, and the built-in amplifier has a response time of less than 1.0 us. The output circuit of the device features a Push-Pull type logic output, allowing the voltage generated by the PIN photo diode to be detected more easily. The logic output can be set to either Active High or Active Low, depending on the application.

The OPB462P11 is suitable for a wide range of applications, such as presence sensing, thickness measurement, and alignment. It can be used in automation equipment, factory production lines, and packaging lines. The OPB462P11 features a wide operating temperature range from -40°C up to +85°C, making it suitable for use in a variety of environments.

In summary, the OPB462P11 is a photointerrupter featuring a logic output that can be used in a wide variety of applications. The built-in amplifier provides a fast response time, and the wide operating temperature range ensures reliable operation in any environment. The device is suitable for presence sensing, thickness measurement, and alignment applications, and is an ideal solution for automation equipment, factory production lines, and packaging lines.
