Optical Sensors encompass a wide variety of devices. One subclass of optical sensors is the photointerrupter. Within this subclass, one type of photointerrupter is the Slot Type, and this type has transistor output. One example of a Slot Type Transistor Output photointerrupter is EE-SX1320, manufactured by Omron Corporation. This article will discuss the application field and working principle of EE-SX1320.

EE-SX1320 is mainly used for counting or position sensing applications. It is widely used in the industrial automation, home appliance, and office equipment industries. A few examples of its usage include electronic equipment power control, control panel selection, document sorting, and shelf-life monitoring. Specifically, it is used in applications requiring switching based on the presence or absence of an object, such as part selection, height detection, thickness measurement, or material density detection.

The working principle of EE-SX1320 is based on the photoelectric area scanning technology. It consists of an infrared light emitting diode (LED) on the transmitter side and a light-sensitive element on the receiver side. The transmitter shines infrared light on the receiver and the receiver converts the light into an electrical signal. If there is an object in between the transmitter and receiver, the light is blocked and the signal is changed. This signal can be detected and used to trigger an action. The EE-SX1320 is designed for mounting on a printed circuit board (PCB), and it has a standard mounting hole size.

The EE-SX1320 has a sensing distance of 1 to 3 mm, a response time of 3.2 μs, a voltage rating of 5 to 24 VDC, and a current rating of 20 mA. The LED has a turn-on voltage of 2.5 V and a turn-off voltage of 1.2 V. It is also designed with a built-in fast response circuit with oscillating frequency of 20 kHz. It has a high voltage protection of ±14 V and the output is switch NF2. The EE-SX1320 is also highly reliable, with a mechanical life of 100 million operations and electrical life of 50 billion operations.

The EE-SX1320 is designed for mounting on a printed circuit board (PCB).The mounting hole size is standard and easy to install, for trouble-free wiring and secure connection. The integrated design of the EE-SX1320 also eliminates the need for wiring or soldering, allowing for easy installation and maintenance. In addition, the EE-SX1320 is sealed in a dust-proof case, making it suitable for a wide range of harsh environments.

The EE-SX1320 is a highly reliable and versatile Slot Type Transistor Output photointerrupter. Its working principle is based on the photoelectric area scanning technology, making it an ideal choice for counting and position sensing applications. Moreover, its integrated design and high reliability make it suitable for a wide range of applications in the industrial automation, home appliance, and office equipment industries.
