The EE-SK3W-B photointerrupter is an optical sensor with a transistor output intended for slot-type applications. This device measures the light transmission across an object, like a paper or card, with an electric output. It is widely used in various industries as a way to detect the presence of an object, as well as in automated manufacturing systems.

The EE-SK3W-B consists of an LED and phototransistor, arranged in such a way that the phototransistor is sensitive to changes in ambient light and the LED is able to emit light that passes through an object. The device is mounted in an orientation so that any interruption of the light between the LED and phototransistor will result in a change in the electrical output of the device. The output of the device is a TTL compatible digital signal, which can be read by the controlling system.

The EE-SK3W-B is used in a variety of applications, such as paper detection, card sorting, and fabric inspection. In paper detection applications, the EE-SK3W-B is used to detect the presence of a paper object such as a paper ticket or form. The device is mounted so that the LED\'s output beam passes through the ticket or form and is detected by the phototransistor. When the ticket or form passes through the beam, the phototransistor will produce an electrical output, which can be read by the controlling system.

In card sorting applications, the EE-SK3W-B is used to detect the presence of a card and sort it into different compartments. The device is mounted so that the LED emits a beam that passes through a card as it is placed into the sorting machine. When a card passes through the beam, the phototransistor produces an electrical output which the controlling system can read to determine which compartment the card needs to be placed in.

In fabric inspection applications, the EE-SK3W-B is used to detect the presence of flaws in fabric. The LED is used to emit a beam which passes through the fabric and is detected by the phototransistor. If a flaw is present in the fabric, the beam will be blocked and the output of the device will indicate the presence of the flaw.

The EE-SK3W-B is an excellent choice for a variety of applications, as it is easy to mount, and requires minimal power to operate. It is reliable and accurate, making it a popular choice for many industries and applications. The EE-SK3W-B is a cost effective solution for detecting and sorting objects and materials, and for detecting flaws in fabric.
