Photointerrupters are optoelectronic devices that use optical sensors to detect the presence of a target object in their view. The EE-SA104 is a slot type photointerrupter with transistor output, specifically designed for applications such as detecting the position and speed of rotating objects. It works by interrupting an infrared emitting diode (IED) when the target reaches between the emitter and receiver of the photointerrupter, triggering a switch which then delivers a signal.

The EE-SA104 has a built-in photoelectric converter integrated into the optoelectronic device. Its infrared LED emits a light beam through its slot, when an object passes through the slot the light beam is blocked and then detected. The transistor receives the switch-on signal directly, allowing easier wiring and also improving the response time of the device.

These devices have numerous applications in prototyping and automation, such as counting objects that pass by, detecting the stopping of movement, determining the speed of objects in motion, as well as detecting any changes in the light or infrared transmission. All this is possible thanks to the 3.5 mA current that passes through the EE-SA104 when it detects the presence of an object.

The EE-SA 104 type of photointerrupter has a case made of nickel-plated copper and black resin, and uses a connecting pin arrangement which makes it suitable to use for a wide range of applciations. Thanks to its external design and good sealing, it also operates well under dusty, humid, and oily conditions if the proper precautions are taken.

When using the device, it is important to set up the working voltage according to the ambient environment in order to minimize errors. The device should also be connected in a way so that the slot is facing the transmitter and receiver as this will ensure the correct operation of the EE-SA104.

The working frequency of the EE-SA 104 is 3 kHz and its minimum resolution is 8 mm, 100 ms is its response time and 4 mm is its detection range. The operating temperature range of the device is between -20 to +70°C and a voltage between 6 and 24 VDC. Additionally, the device is RoHS compliant and has a dielectric strength of 5 kV/mm.

In conclusion, the EE-SA104 is a slot-type photointerrupter designed for use in automation applications. It uses a transistor output for detecting the presence of a target object within its view. The design of the EE-SA104 is highly reliable and cost-effective, making it a great option for applications such as counting objects passing by, detecting speed of objects and changes in the light or infrared transmission.
