Optical Sensors - Photointerrupters - Slot Type - Transistor Output are widely used in various applications and have a variety of working principles. The EE-SJ3-G is a type of photointerrupter that has an output transistor with a slot to sense objects passing through. The EE-SJ3-G is a high-speed, small-sized switch that can detect positions and measure movement in processes that involve speed and rotation. It is also able to cancel noise outside of its sensing field to enable reliable operation.

The EE-SJ3-G functions by using an LED emitter and an integrated phototransistor. Light from the LED emitter passes through a slot and is then detected by the phototransistor. When an object passes directly through the slot, the phototransistor detects the change in light intensity and the output transistor is activated, producing an output signal. The output is designed for a wide range of voltage levels, including TTL and CMOS digital circuits.

The EE-SJ3-G has a variety of features that make it a popular choice for many applications. It is a surface-mount device with a narrow body size to save space and a low profile that is less vulnerable to mechanical interference. The EE-SJ3-G has a long sensing distance of up to 20 mm, a fast response speed of 1.2 ms, and a high level of temperature stability and resistance to noise. It is also highly durable, with a mechanical life of up to 200 million switchings.

Due to its robust features, the EE-SJ3-G has many potential applications. It is often used in industrial automation applications such as motor position detection, gate monitoring, counting systems, and rotary sensor systems. It is also well suited for use in medical equipment, household appliances, vending machines, electronic toys, and other consumer products.

The EE-SJ3-G is a powerful and versatile solution for many applications. Its small size, long sensing distance, high response speed, and low profile make it ideal for tight spaces and challenging environments. Its robust construction and reliable operation ensure that it can provide accurate and reliable results for many years. With a wide range of applications and a durable design, the EE-SJ3-G is a reliable choice for many users.
