Optical Sensors - Photointerrupters - Slot Type - Transistor Output

Optical sensors, or photointerrupters, are components that detect presence or absence of objects by sensing a change in ambient light levels when an object passes between the sensor\'s light source and detector. The H22B3 is a slot type photointerrupter with a transistor output. It is commonly used in a wide range of applications.

Features

The H22B3 is a small device with dimensions of just 2.3mm (W) x 5.2mm (L) x 1.5mm (H). The device is housed in a robust black mold package and features a built-in infrared transmitter and receiver. The device has a wide operating voltage range of 4.5V to 24V and a switching frequency of up to 600Hz. It has a long service life of up to 100,000 cycles. It is also moisture and dustproof.

Application fields

The H22B3 is ideal for a variety of applications, including motion detection, door and window sensing, security systems, automatic packaging machines, health care equipment, automotive, industrial automation, robotic arms and agricultural machinery. It is widely used in current sensing, security systems, position sensing, and many other applications. The device can be used in a variety of industrial, automotive, and medical applications.

Working principle

The H22B3 consists of a transmitter and receiver in the same package. When the object block the light between the transmitter and receiver, the signal of transmitter is received by the receiver and the collector of the receiver output transistor provides an “on” signal. When the object no longer blocks the light, the signal of the receiver is no longer received and the “off” signal is provided.The H22B3 is a versatile device with a simple setup and operation. It has a short response time of just 3 to 5 milliseconds and has a high reliability and long service life. The device is also dust and moisture-proof and is easy to install.

Conclusion

The H22B3 is an extremely reliable and versatile slot type photointerrupter with a transistor output. It is widely used in a variety of applications, including motion detection, door and window sensing, security systems, automatic packaging machines, health care equipment, automotive, industrial automation, robotic arms and agricultural machinery. The device features a built-in infrared transmitter and receiver, wide operating voltage range, high switching frequency, long service life and moisture and dust-proof design. The H22B3 has a short response time and provides high reliability and long service life.
