Optical Sensors are electronic components which detect light emitted by an object and convert it into electrical signals. Photointerrupters, among optical sensors, are devices used to interrupt light beams, which in turn, detect the passage of an object within its optical path. Slot type photointerrupters, like the SFH 9500, use a slot-type photointerrupter which has an open slit-type emitter and receiver side-by-side.

The SFH 9500 is a slot type photointerrupter with a transistor output. It has a low off-state output current and a quick turn-on time. As an environmental friendly optical switch, the SFH 9500 uses an internal infrared LED as its emitter and a phototransistor as its receiver. The device is housed in a miniature package with a low profile.

The SFH 9500 process as follows. When the infrared LED is activated, its light beam passes through the open slit and reaches the phototransistor. This phototransistor is electrically isolated from the LED and can generate an electrical output signal when illuminated by the LED. When the object interrupts the light beam, the phototransistor stops generating the electrical output signal.

The SFH 9500 offers a high on/off ratio, wide operating current, long lifetime, and low power consumption. It is suitable for a range of applications, such as motion detection, proximity detection, light barcode detection, and photocopier. The device can also be used in vending machines, office automation equipment, and consumer electronics.

The SFH 9500 offers a high degree of reliability and is highly resistant to environmental conditions. It has a superior ESD protection of ±2kV and a high insulation resistance of 100MΩ. The device is also RoHS compliant and halogen-free, making it suitable for a number of industrial applications.

The SFH 9500 is designed for reliable detection of objects, such as a light beam or opening slot, for a wide range of applications. The device utilizes a highly sensitive phototransistor, which can detect the smallest objects passing through the optical path. The SFH 9500 is a reliable, low-power, and environmentally friendly optical switch, making it an ideal solution for a variety of applications.
