Optical sensors are ubiquitous in all sorts of applications. They’ve been utilized in industrial, automotive, consumer and other settings to detect objects and enable efficient control of a system. One particular type of optical sensor that is often used is the photointerrupter; this is a a device which uses a light-activated switch to detect the presence of an object. In particular, SL-A13 photointerrupters consist of a light-emitting diode, an LED, and a phototransistor that are enclosed in a small plastic package.

SL-A13 photointerrupters are slot type photointerrupters with logic output that are typically used in applications that require high accuracy and quick response times. Some of the most common applications for this type of photointerrupter include motion sensing, solid-state relays, electronic garage door openers, and robotics. The SL-A13 photointerrupter is also ideal for applications where precise speed measurements are necessary.

The SL-A13 photointerrupter uses a light-emitting diode and phototransistor to detect objects. The light-emitting diode emits a beam of light, which is then detected by the phototransistor. When the phototransistor receives the light, it creates an electrical signal. This signal is then sent to a logic circuit to generate either a "high" or "low" level output signal, depending on whether the phototransistor is triggered or not.

The SL-A13 photointerrupter has several features that make it an ideal choice for many applications. It has a double integral structure and provides an extremely small response time of only 0.8ms. In addition, it has an operating voltage of 5V, a current rating of 50mA, and a wide operating temperature range from -40°C to +85°C. The SL-A13 also has excellent optical modulation characteristics with a wide “ON”, “OFF”, and “SAT” time window.

In addition, the SL-A13 photointerrupter has a high impedance input to the phototransistor to reduce power consumption. The “ON” and “OFF” output levels also remain independent of ambient light intensity, and the device is relatively immune to light contamination. Finally, it has a minimum isolation voltage of 2450Vrms, providing protection against electrical noise.

The SL-A13 is an ideal solution for applications where fast, accurate, high-precision detection is required. Its fast response time and high immunity to light contamination make it suitable for a wide range of applications, including motion sensing, electronic garage door openers, and robotics. It is also compatible with various logic circuits, making it a useful addition to any automation system.
